I know, it’s quite annoying when your ipod battery is flat only a handful of hrs into a prolonged journey. No audio, no audio publications, gee you’ll have to imagine of one thing else to do. Or possibly it’s your cell cell phone that is very low on charge and you require to speak to somebody. You hear people dreaded beeps and then the cellular phone goes dead. You’ll have to get a cell phone box someplace – a person that works that is. I guess I’m as guilty as the subsequent person when I want my entertainment or organization all set at the touch of a button. That’s likely why I have a lot more gadgets and hand held devices than I treatment to think about. However they all want energy and quite frequently I overlook to cost them totally leaving me stranded. The resolution to this challenge is to use a portable photo voltaic energy generator.

There are rather a few transportable solar energy generators around at the second. They all have the exact same essential set up. A quantity of solar panels will soak up photons from sunlight to generate electrical power. This is stored in a battery such as Asus A42-A3 Battery, Asus A8F Battery, Asus F3T Battery, Asus F3Sc Battery, Asus F3Sv Battery, Asus 90-NI11B1000 Battery, Asus 90-NIA1B1000 Battery, Asus 90-NF51B1000 Battery, Asus 70-NF51B1000 Battery, Asus A32-A8 Battery, Asus Z99J Battery, Asus Z99H Battery, like a lithium ion battery that you may well uncover in laptops. The generator has an electrical power level where various units can be plugged in to use the latest of the battery as if they exactly where plugged into a wall socket. The advantage of the photo voltaic generator is that if it is working minimal on charge then sunlight will assist to leading it up. Supplied there is some sun out the battery will often be charging. This should imply that what ever hand held unit you may be using will constantly have a possible energy source and you will under no circumstances have that flat battery expertise yet again.

Photo voltaic Energy For My House – Is it Probable?

Several individuals are annoyed by the escalating electricity bill in their houses. The fact is that the price of gasoline and electrical power is high and it is not probable to reduce the charges. As a common individual, you would like to preserve your electrical energy bill and use that cash on some thing that is genuinely beneficial for you.

The fantastic news for all of us is that you can use the non-polluting, photo voltaic vitality to provide power for your residence. Solar electric power for my household – if this is what you are thinking about, examine on.

The Benefits of Setting up Photo voltaic Energy Devices

If we overlook the monetary benefits, these devices also have a wonderful fantastic affect on the setting. This is since solar power is a renewable resource of power. Solar electrical energy tools do not output hazardous gases or other chemical compounds. Considering that they do not lead for the demand of gasoline, it helps to continue to keep a country’s transportation expenditures at a lowered stage.

Along with the previously mentioned positive aspects, photo voltaic programs also have number of adverse points. The higher first cost can be 1 of the key restrictions for a person to not go for a photo voltaic method. These gear can be a bit overpriced to setup mainly because of the charge of materials and the talent amounts of personnel involved. Mainly because a large open region is needed for installation, solar panels is not an possibility for people living in rural apartments. Yet another drawback could be the volume of sun light it gets in the course of a variety of seasons. If the amount of sunshine revived in a certain country varies during seasons, it can get a noticeably lengthier time to see an effective return on investment.

How A great deal Strength Does Photo voltaic Strength Create?

Older engineering lost as substantially electric power in the transmission as it delivered. The more recent crystalline silicon cells and this photo voltaic film engineering is significantly more successful. A procedure which utilized to shell out for alone in eight years at ideal can now oftentimes indicate a good return in significantly less than a yr and a fifty percent.

Satellite photo voltaic electrical power is most successful, while there are sizeable construction and running prices. The sun’s strength is not dissipated by atmospheric intervention in outer space. On earth, the systems that stick to the sun’s progress across the sky like sunflowers provide a lot more energy. The typical and most cost-effective roof-major systems ought to be sited to get as a lot sun as achievable from a stationary placement.

What Should You Look For, When Buying Battery

Welcome to a laptop battery specialist

When buying a battery for your notebook , firstly should look for is the respectability of the item at mind. If the product is made by the manufacturer of your laptop (i.e. Sony, Compaq, Dell, etc),you can be sure about quality. However, alll brands doesnt produce their battery by themselves. For example, when you open Sony laptop battery, you might find that the power cells inside are actually made by Toshiba, Panasonic, or a similar brand company. Here, u can understand Sony produce only plactic box of this battery Many third party brands use the exact same power cells as original manufacturers.

Using a third party manufacturer is often a good way to go when buying a battery such as Asus A42-A3 Battery, Asus A8F Battery, Asus F3T Battery, Asus F3Sc Battery, Asus F3Sv Battery, Asus 90-NI11B1000 Battery, Asus 90-NIA1B1000 Battery, Asus 90-NF51B1000 Battery, Asus 70-NF51B1000 Battery, Asus A32-A8 Battery, Asus Z99J Battery, Asus Z99H Battery, as there are usually many extra benefits. For instance, most third party batteries are much lower in price than original manufacturers batteries. Secondly, they usually grant a superior warranty, as they realize that in order to win the consumer’s respect; they must stand behind their product. A 1-Year Waranty is a must. Dont buy any battery with a warranty less than one year. Batteries have been known to end its life early, and 3-Month Waranty could leave you high and dry.

the next important thing you should look for is the type of battery. Batteries can be made using several chemicals. For laptops, there are four main types. They are Ni-Cad, Ni-MH, Li-Ion, and Li-Poly. There is no major manufacturer that still makes Ni-Cad laptop batteries, as they are a very old and simple type of power. Ni-MH is newest and more advanced, but is not as good as its Li-Ion and Li-Poly counterparts.

If we compare the last three types (Ni-MH, Li-Ion, Li-Poly), we find that Ni-MH batteries weigh more than the other two battery types, but produce less current than the other two. Li-Ion and Li-Poly are the most advanced types of batteries on the market, and you should try to get one of these two types if its possible. Most laptops that come with one type of battery can not use any other type of battery, if u use ni-cad battery , you should replace it with a ni-cad battery. please be carefull about it, this does not apply. Some laptops that come with a Ni-MH battery can be replaced with a stronger Li-Ion one.

Lastly you must be aware of the power rating of the item you are buying. As technology advances, so do power ratings. The battery you bought last year may be twice as strong this year, and might even be the same size. Batteries have two main ratings on them: Volts and Amperes. ,most companies indicate their ratings with Volts and Milliamperes. 1000 Milliamperes = 1 Ampere.

When buying a battery, always look for the battery with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together.

One or two weeks before I make a journey overseas, I make a packing list and check items off as they go in my luggage. In addition to the packing list, I also have my electronic devices list.

With all of the gadgets and gizmos, wires and cables, I need a list to make sure that I have everything. It is no fun to arrive in a foreign country and not be able to use your notebook computer or photographic equipment.

First and foremost, I check my portable computer. I want to make sure that I have everything. So, I check to make sure that I have my power supply and spare battery such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery. I also have an USB device that converts one port into four. I prefer to use a mouse, so I pack that too. I bring a LAN cable in case there is no wireless available in the hotel.

I already have a power strip that will accept 3-prong electrical plugs. This is an absolute must as a 3-prong plug will not work in most Thailand electrical outlets.

Next thing I do is charge up my camcorder batteries. I like to take pictures of my entire holiday to include the departing airport, layover and arrival. I also ensure that I have my memory card and my spares. I also have an USB device for my memory card so that I can transfer pictures to my laptop computer. I check the memory card and delete or transfer any pictures on the card. I like to start my vacation with empty memory cards.

I have a tri-band, GSM cell phone that works in Thailand with a local SIM card. So, I make sure that the battery and back-up are both charged so that I can use my Thai cell phone as soon as I hit the ground in Bangkok.

Next, I check my portable DVD player. I make sure that I have my power cord and also my DIN jacks for the TV to DVD connection. I charge the battery and make sure that I have the small remote control and that the battery is operational.

Packing up all the charger cables and wires on the very top of my luggage makes for easy finding when I arrive.

I also have some minor electronics. I have sound reducing headphones that I pack in my carry-on. No real electronics, but I do make sure that I have 4 AAA batteries. That way I have 2 to use and 2 spares. My portable MP3 player gets charged via USB on my laptop and will last the entire 15 hours I am in the air.

Checking your electronic devices before you go, charging all of your batteries, and packing all the cables and wires, will make your vacation go electronically smooth.

The Fuel Cell Battery Knowledge ( Figure 2 )

Welcome to a laptop battery specialist
of the Acer Laptop Battery   First post by: www.itsbattery.com

A fuel cell is an electrochemical device that combines hydrogen fuel with oxygen to produce electricity, heat and water. The fuel cell is similar to a battery in that an electrochemical reaction takes place as long as fuel is available. The hydrogen fuel is stored in a pressurized container and oxygen is taken from the air. Because of the absence of a burning process, there are no harmful emissions, and the only by-product is fresh water. The water emitted from the proton exchange membrane fuel cell (PEMFC) is so pure that visitors to Vancouver’s Ballard Power Systems were served hot tea made from this clean water.

Fundamentally, a fuel cell is electrolysis in reverse, using two electrodes separated by an electrolyte. The anode (negative electrode) receives the hydrogen and the cathode (positive electrode) collects the oxygen. A catalyst at the anode separates hydrogen into positively charged hydrogen ions and electrons; the oxygen is ionized and migrates across the electrolyte to the anodic compartment, where it combines with hydrogen. A single fuel cell produces 0.6–0.8V under load. To obtain higher voltages, several cells are connected in series. Figure 1 illustrates the concept of a fuel cell.

The fuel cell converts hydrogen and oxygen to electricity and clean water is the only by-product. Fuel cells can be used indoors as an electricity generator.Courtesy of SFC Smart Fuel Cell AG

(2010)

Alkaline Fuel Cell (AFC)

The alkaline fuel cell has become the preferred technology for aerospace, including the space shuttle. Manufacturing and operating costs are low, especially for the stack. While the separator for the PEM costs between $800 and $1,100 per square meter, the same material for the alkaline system is almost negligible. (The separator for a lead acid battery such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery costs $5 per square meter.) Water management is simple and does not need compressors and other peripherals. A negative is that AFC is larger in physical size than the PEM and needs pure oxygen and hydrogen as fuels. Carbon dioxide in a polluted city can poison the stack.

Solid Oxide Fuel Cell (SOFC)

Electric utilities use three types of fuel cells, which are molten carbonate, phosphoric acidand solid oxide fuel cells. Among these choices, the solid oxide (SOFC) is the least developed but has received renewed attention because of breakthroughs in cell material and stack design. Rather than operating at the very high operating temperature of 800–1,000°C (1,472–1,832°F), a new generation of ceramic material has brought the core down to a more manageable 500–600°C (932–1,112°F). This allows the use of conventional stainless steel rather than expensive ceramics for auxiliary parts.

High temperature allows direct extraction of hydrogen from natural gas through a catalytic reforming process. Carbon monoxide, a contaminant for the PEM, is a fuel for the SOFC. Being able to accept carbon-based fuels without a designated reformer and delivering high efficiency pose significant advantages for this type of fuel cell. Cogeneration by running steam generators from the heat by-product raises the SOFC to 60 percent efficiency, one of the highest among fuel cells. As a negative, high stack temperatures require exotic materials for the core that add to manufacturing costs, lower longevity and decrease reliability. With the newer SOFC systems operating at lower temperatures, however, this drawback has been reduced.

Battery Technology Charging lithium-ion batteries

Welcome to a laptop battery specialist
of the Acer Laptop Battery   First post by: www.itsbattery.com

There is only one way to charge lithium-based batteries. The so-called ‘miracle chargers’, which claim to restore and prolong batteries, do not exist for lithium chemistries. Neither does super-fast charging apply.

Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers “typical” charge technique.

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

Most cells are charged to 4.20 volts with a tolerance of +/?0.05V/cell. Charging only to 4.10V reduced the capacity by 10% but provides a longer service life. Newer cell are capable of delivering a good cycle count with a charge to 4.20 volts per cell. Figure 1 shows the voltage and current signature as the lithium-ion cell passes through the charge stages.

Figure 1: Charge stages of a lithium-ion battery such as Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery, Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery. Increasing the charge current on a lithium-ion charger does not shorten the charge time by much.

Although the voltage peak is reached quicker with higher current, the topping charge will take longer.The charge time of most chargers is about 3 hours. Smaller batteries used for cell phones can be charged at 1C; the larger 18650 cell used for laptops should be charged at 0.8C or less. The charge efficiency is 99.9% and the battery remains cool during charge. Full charge is attained after the voltage threshold has been reached and the current has dropped to 3% of the rated current or has leveled off.

Increasing the charge current does not shorten the charge time by much. Although the voltage peak is reached quicker with higher charge current, the topping charge will take longer.

Some chargers claim to fast-charge a lithium-ion battery in one hour or less. Such a charger eliminates stage 2 and goes directly to ‘ready’ once the voltage threshold is reached at the end of stage 1. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.

No trickle charge is applied because lithium-ion is unable to absorb overcharge. A continuous trickle charge above 4.05V/cell would causes plating of metallic lithium that could lead to instabilities and compromise safety. Instead, a brief topping charge is provided to compensate for the small self-discharge the battery and its protective circuit consume. Depending on the battery, a topping charge may be repeated once every 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05V/cell and turns off at a high 4.20V/cell.

What happens if a battery is inadvertently overcharged? lithium-ion is designed to operate safely within their normal operating voltage but become unstable if charged to higher voltages. When charging above 4.30V, the cell causes plating of metallic lithium on the anode; the cathode material becomes an oxidizing agent, loses stability and releases oxygen. Overcharging causes the cell to heat up. If left unattended, the cell could vent with flame.

Much attention is focused to avoid over-charging and over-discharging. Commercial lithium ion packs contain a protection circuits that limit the charge voltage to 4.30V/cell, 0.10 volts higher than the voltage threshold of the charger. Temperature sensing disconnects the charge if the cell temperature approaches 90°C (194°F), and a mechanical pressure switch on many cells permanently interrupt the current path if a safe pressure threshold is exceeded. Exceptions are made on some spinel (manganese) packs containing one or two small cells.

Extreme low voltage must also be prevented. The safety circuit is designed to cut off the current path if the battery is inadvertently discharged below 2.50V/cell. At this voltage, most circuits render the battery unserviceable and a recharge on a regular charger is not possible.

There are several safeguards to prevent excessive discharge. The equipment protects the battery by cutting off when the cell reaches 2.7 to 3.0V/cell. Battery manufacturers ship the batteries with a 40% charge to allow some self-discharge during storage. Advanced batteries contain a wake-up feature in which the protection circuit only starts to draw current after the battery has been activated with a brief charge. This allows prolonged storage.

In spite of these preventive measures, over-discharge does occur. Advanced battery analyzers (Cadex C7000 series) feature a ‘boost’ function that provides a gentle charge current to activate the safety circuit and re-energize the cells if discharged too deeply. A full charge and analysis follows.

If the cells have dwelled at 1.5V/cell and lower for a few days, however, a recharge should be avoided. Copper shunts may have formed inside the cells, leading a partial or total electrical short. The cell becomes unstable. Charging such a battery would cause excessive heat and safety could not be assured.

Battery experts agree that charging lithium-ion batteries is simpler and more straightforward than the nickel-based cousins. Besides meeting the tight voltage tolerances, the charge circuit can be designed with fewer variables to consider. Full-charge detection by applying voltage limits and observing the current saturations on full charge is simpler than analyzing many complex signatures, which nickel-metal-hydride produces. Charge currents are less critical and can vary. A low current still permits proper full charge detection. The battery simply takes longer to charge. The absence of topping and trickle charge also help in simplifying the charger. Best of all, there is no memory but aging issues are the drawback.

The charge process of a lithium-ion-polymer is similar to lithium-ion. These batteries use a gelled electrolyte to improve conductivity. In most cases, lithium-ion and lithium-ion-polymer share the same charger.

Figure:

Concept of a fuel cell

The anode (negative electrode) receives the hydrogen and the cathode (positive electrode) collects the oxygen.

Source: US Department of Energy, Office of Energy Efficiency and Renewable Energy Fuel cell technology is twice as efficient as combustion in turning carbon fuel to energy. Hydrogen, the simplest chemical element (one proton and one electron), is plentiful and exceptionally clean as a fuel. Hydrogen makes up 90 percent of the universe and is the third most abundant element on the earth’s surface. Such a wealth of fuel would provide an almost unlimited pool of clean energy at relatively low cost. But there is a hitch. Hydrogen is usually bound to other substances and “unleashing” the gas takes technology and a substantial amount of energy. In terms of net calorific value (NCV), hydrogen is more costly to produce than gasoline. Some say that hydrogen is nearly energy neutral, meaning that it takes as much energy to produce as it delivers at the end destination.

Storage of hydrogen poses a further disadvantage. Pressurized hydrogen requires heavy steel tanks, and the NCV by volume is about 24-times lower than a liquid petroleum product. In liquid form, which is much denser, hydrogen needs extensive insulation for cold storage.

Hydrogen can also be produced with a reformer by means of extraction from an existing fuel, such as methanol, propane, butane or natural gas. Converting these fossil fuels into pure hydrogen releases some leftover carbon, but this is 90 percent less harmful than what comes from the tailpipe of a car. Carrying a reformer would add weight to the vehicle and increase its cost. Reformers are also known to be sluggish.

The net benefit of hydrogen conversion is in question because it does not solve the energy problem. With the availability of hydrogen through extraction, the fuel cell core (stack) to convert hydrogen and oxygen to electricity is expensive and the stack has a limited life span. Burning fossil fuels in a combustion engine is the simplest and most effective means of harnessing energy, but this contributes to pollution.

Sir William Grove, a Welsh judge and gentleman scientist, developed the fuel cell concept in 1839, but the invention never took off. This was in part due to the rapidly advancing internal combustion engine, which promised better results. It was not until the 1960s that the fuel cell was put to practical use during the Gemini space program. NASA preferred this clean power source to nuclear or solar power. The alkaline fuel cell system generated electricity and produced the drinking water for the astronauts.

High material costs made the fuel cell prohibitive for commercial use at that time. This did not hinder Karl Kordesch, the co-inventor of the alkaline battery such as Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery, Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, from converting his car’s power source to an alkaline fuel cell in the early 1970s. Kordesch drove his car for many years in Ohio, USA. He placed the hydrogen tank on the roof and utilized the trunk to place the fuel cell as well as backup batteries. According to Kordesch, there was “enough room for four people and a dog.” The 1990s brought renewed interest in the fuel cell; however, this enthusiasm started to diminish again in the 21st century.

Just as there are different battery chemistries, so also are there several fuel cell systems to choose from. Let’s look at the most common types and examine the applications.

Proton Exchange Membrane Fuel Cell (PEMFC)

The proton exchange membrane, also known as PEM, uses a polymer electrolyte. PEM is one of the furthest developed and most commonly used fuel cell systems; it powers cars, serves as a portable power source and provides backup power in lieu of stationary batteries in offices. The PEM system allows compact design and achieves a high energy-to-weight ratio. Another advantage is a relatively quick start-up when applying hydrogen. The stack runs at a moderate temperature of 80°C (176°F) and has a 50 percent efficiency. (In comparison, the internal combustion engine is only about 25 percent efficient.)

The limitations of the PEM fuel cell are high manufacturing costs and complex water management systems. The stack contains hydrogen, oxygen and water. If dry, water must be added to get the system going; too much water causes flooding. The system requires pure hydrogen; lower fuel grades can cause decomposition and clogging of the membrane. Testing and repairing a stack is difficult, given that a 150V, 50kW stack to power a small car requires 250 cells.

Extreme operating temperatures are a further challenge. Freezing water can damage the stack, and the manufacturer recommends heating elements to prevent ice formation. When the fuel cell is cold, start-up is slow and the performance is poor at first. Excessive heat can also cause damage. Controlling the operating temperatures as well as supplying enough oxygen requires compressors, pumps and other accessories that consume about 30 percent of the energy generated.

If operated in a vehicle, the PEMFC stack has an estimated service life of 2,000-4,000 hours. Start-and-stop conditions induce drying and wetting that contribute to membrane stress. Running continuously, the stationary stack is good for about 40,000 hours. Stack replacement is a major expense. Figure 2 illustrates a portable fuel cell.

Electrode lets lithium batteries charge in just two minutes

Welcome to a laptop battery specialist
of the Acer Laptop Battery   First post by: www.itsbattery.com

Batteries are an essential part of most modern gadgets, and their role is expected to expand as they’re incorporated into vehicles and the electric grid itself. But batteries can’t move charge as quickly as some competing devices like supercapacitors, and their performance tends to degrade significantly with time. That has sent lots of materials science types into the lab, trying to find ways to push back these limits, sometimes with notable success. Over the weekend, there was another report on a technology that enables fast battery charging. The good news is that it uses a completely different approach and technology than the previous effort, and can work with both lithium- and nickel-based batteries such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery.

The previous work was lithium-specific, and focused on one limit to a battery’s recharge rate: how quickly the lithium ions could move within the battery material. By providing greater access to the electrodes, the authors allowed more ions to quickly exchange charge, resulting in a battery with a prodigious charging rate. The researchers increased lithium’s transport within the battery by changing the structure of the battery’s primary material, LiFePO4.

The new work also gets fast charges, but by a rather different route. The authors, from the University of Illinois, don’t focus on the speed of the lithium ions in the battery; instead, they attempt to reduce the distance the ions have to travel before reaching an electrode. As they point out, the time involved in lithium diffusion increases with the square of the distance travelled, so cutting that down can have a very dramatic effect. To reduce this distance, they focus on creating a carefully structured cathode.

The process by which they do this is fairly simple, and lends itself to mass production. They started with a collection of spherical polystyrene pellets. By adjusting the size of these pellets (they used 1.8µm and 466nm pellets), they could adjust the spacing of the electrode features. Once the spheres were packed in place, a layer of opal (a form of silica) was formed on top of them, locking the pattern in place with a more robust material. After that, a layer of nickel was electrodeposited on the opal, which was then etched away. The porosity of the nickel layer was then increased using electropolishing.

When the process was done, the porosity—a measure of the empty space in the structure—was about 94 percent, just below the theoretical limit of 96 percent. The authors were left with a nickel wire mesh that was mostly empty space.

Into these voids went the battery material, either nickel-metal hydride (NiMH) or a lithium-treated manganese dioxide. The arrangement provides three major advantages, according to the authors: an electrolyte pore network that enables rapid ion transport, a short diffusion distance for the ions to meet the electrodes, and an electrode with high electron conductivity. All of these make for a battery that acts a lot like a supercapacitor when it comes to charge/discharge rates.

With the NiMH battery material, the electrodes could deliver 75 percent of the normal capacity of the battery in 2.7 seconds; it only took 20 seconds to recharge it to 90 percent of its capacity, and these values were stable for 100 charge/discharge cycles. The lithium material didn’t work quite as well, but was still impressive. At high rates of discharge, it could handle 75 percent of its normal capacity, and still stored a third of its regular capacity when discharged at over a thousand times the normal rate.

A full-scale lithium battery made with the electrode could be charged to 75 percent within a minute, and hit 90 percent within two minutes.

There are a few nice features of this work. As the authors noted, the electrodes are created using techniques that can scale to mass production, and the electrodes themselves could work with a variety of battery materials, such as the lithium and nickel used here. It may also be possible to merge them with the LiFePO4 used in the earlier work. A fully integrated system, with materials designed to work specifically with these electrodes, could increase their performance even further.

Of course, that ultimately pushes us up against the issue of supplying sufficient current in the short time frames needed to charge the battery this fast. It might work great for a small battery, like a cell phone, but could create challenges if we’re looking to create a fast-charge laptop.

Battery Technology: A Battery That Charges in Seconds

Welcome to a laptop battery specialist
of the Acer Laptop Battery   First post by: www.itsbattery.com

Imagine being able to charge your cell phone in a matter of seconds or your laptop in a few minutes. That might soon be possible, thanks to a new kind of nanostructured battery electrode developed by scientists at the University of Illinois, Urbana-Champaign. The researchers found that their electrode can charge and discharge up to 100 times faster than existing devices while holding the same amount of energy.

High-storage batteries that could charge and discharge quickly might make a number of still-marginal technologies much more attractive. For example, if you could recharge an electric car in minutes rather than hours, filling up your battery at a charging station would take no longer than the amount of time it takes to buy a tank of gas. And batteries that gave up their stored energy quickly could mean uninterrupted solar power, pitching in when the sun goes behind a cloud and solar cells stop producing.

Electrical storage devices known as capacitors charge and discharge very quickly, but because they hold their charge on the surface of metal plates, their storage capacity is limited. Batteries, on the other hand, can store much more energy because they hold their charge inside the bulk of a material, usually an oxide or a phosphate compound located inside the cathode. Unfortunately, because these materials are not good conductors of electric charge, it takes a long time to get the charge in or out of a battery.

Scientists have tried to get around this problem in the past by adding electrical conductors to the energy-storage material, but this reduces the material’s volume, so it tends to lower the battery’s capacity. University of Illinois materials scientist Paul Braun and his colleagues came up with a novel solution, published online this month in Nature Nanotechnology. They built a tiny metal lattice with so many nooks and crannies that when it’s filled with a charge-storage material, the electrons in the material never have far to go before reaching the metal and being conducted away.

The Illinois researchers made their electrode by coating a surface with tiny polystyrene spheres just a few hundred nanometers across, packing the spheres together into a regular lattice structure. Then they filled the gaps between the spheres with nickel and dissolved the polystyrene. That left a three-dimensional metal scaffold, which they thinned down so that the metal made up just 6% of the total volume, and they then coated a thin film of the storage material onto the scaffold. The team used this technique to make cathodes for lithium-ion and nickel-metal hydride batteries such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery, with the former used in many consumer electronics devices such as laptops and cell phones whereas the latter are used in many electric vehicles.

Its storage capacity was actually slightly larger than normal (by about 10% to 20%). And because every step of their manufacturing process is used in industry today, the researchers say there should be no major problems with incorporating their cathodes into commercial batteries. They just need to show how to scale up their technology—so far they’ve tried it only on watch-size batteries. “I have every reason to believe we can scale up,” says Braun, “and we are looking to partner with the right people to do that.”

However, materials scientist Yury Gogotsi of Drexel University in Philadelphia, Pennsylvania, sounds a note of caution. Although he says the latest work shows the importance of a smart electrode design that uses common materials, he questions how long the batteries can withstand continued charging and recharging over such short intervals. He is also less sanguine about scaling up. “Braun’s group provides an advantage in rate performance,” he says. “The next step will be to find a simpler way of making three-dimensional electrodes.”

Brief about Connections of a characteristic laptop battery

A laptop battery pack includes a battery of cells, a casing or housing to protect and contain the cells, interconnect means for interconnecting the cells within the casing and conductors running from the interconnected cells to external terminations. The pack also includes a thermally sensitive circuit breaker which serves to disconnect the cells in the event of excessive cell temperatures. The battery pack may include a measuring-resistor strap having two projecting measuring contacts, which forms a portion of the conductors that couples the battery terminals and pack terminals.

A separate current-measuring circuit mounted in the housing provided in the battery pack is coupled to the projecting measuring contacts. A control module in the battery pack receives signals representative of cell voltage, temperature derived from a temperature sensor arranged in thermal contact with the cell and cell current derived by measuring the voltage across a sensing resistor with respect to the external negative voltage. A thermally sensitive circuit breaker provided in the battery pack is in thermal contact with the battery cells and is arranged to disconnect the cell current in case of excessive cell temperature. Usually the laptop battery consists of chemical cells and digital circuit. The success rate of the laptop battery depends on the battery type. Laptop batteries such as Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery, Acer BATCL50L Battery, Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery can be repaired but the work is often time consuming.

A characteristic laptop battery connection consists of positive and negative battery terminals, thermistor, clock and data. The positive and negative battery terminals are located at the outer edges of the connector. The positive and negative battery terminals have elasticity of demand to connect the battery outer shell. A thermistor wire is provided at the outside to allow for temperature protection. The most common thermistors are 10 Kilo Ohm NTC or 10kOhm at 20°C or 68°F. It is always better to use the thermistor during charge and discharge to protect the battery against overheating. The inner contacts accommodate the clock and data. Clock and data are usually combined on a one-wire system. The permanent data contained in the battery is programmed into the battery at time of manufacture. The permanent data includes battery type, battery ID number, serial number, battery manufacturer and date of manufacture. The temporary data contained in the battery is acquired during use and consists of cycle count, user pattern and maintenance requirements.

The fix terminal included in some laptop battery is made of flexible material and is adjustable for angle of demand. The fix terminal is selected from the group consisting of 30 degree, 45 degree, 60 degree, 90 degree and 180 degree. Some laptop batteries may have a solid-state switch that is normally in the OFF position. The battery will turn ON when the switch terminal is connected to the ground. Some laptop battery even includes an end-of-battery-life switch which is used to stop the functioning of the battery at a preset capacity level.

The laptop battery is mostly made of two-wire system architecture. The two-wire system is usually configured to the System Management Bus (SMBus). The SMBus is based on a two-wire system using a standardized communications protocol. The SMBus battery has five or more battery connections. The connections of SMBus battery are commonly safe but testing this type of battery appears complicated. In future, intelligent rechargeable battery packs may include some control or monitoring means to provide charge current control during recharge, charge monitoring during discharge and charge, display of battery condition, and transmission of battery condition or other parameters to external equipment.

New laptop battery tips: This document explains how we recommend you should fully condition your new laptop battery, using a simple battery charge. This will ensure a long battery life and greater durability. It is very common for customers to believe that there is a failure of the battery when in reality they have a battery in perfect condition, which simply requires proper conditioning.

When you receive your battery new laptop, it will be fully paid and unconditional. Please do not turn on your computer when the laptop battery does not work right away. Your battery will normally 8 to 10 cells and releases from reaching its full capacity. However, your battery will not reach their full potential until it has been conditioned for at least fifty times. Until then, you may experience lower performance.

Another common situation you may encounter is the LED indicator on your computer laptop does not give specific information that the Battery is fully air conditioned - it is very common for consumers to believe that their battery is defective. Please do not blame the battery such as Acer BTP-43D1 Battery, Acer TravelMate 220 Battery, Acer BTP-58A1 Battery, acer BTP-60A1 Battery, Acer TravelMate 240 Battery, Acer BTP-52EW Battery, Acer BTP-63D1 Battery, Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery! Just follow the instructions below cycle.

During the first charge, your computer may indicate that the mobile charge is complete after a short period (about 15 minutes). It must be expected and considered normal if this happens, remove the battery from your computer laptop and repeat the charging procedure. You must use your computer laptop as usual (without AC adapter plugged in), until the battery is completely down.

Repeat the above procedure for a minimum of eight times in the coming days. Always make sure you allow time for your battery is sufficient to obtain a full charge overnight.

What do these terms mean ?

Cycle - One full load during the night and a full discharge and without the adapter plugged in.

Charge - Night of charge with an AC adapter plugged into the mains.

Discharge - have exhausted the power of your battery (operating thecomputer with your battery is fully charged in thecomputer laptop and AC adapter unplugged).

Condition - This is the process of charge / discharge you must complete. This will increase both the performance and life of your battery.

Duration - The time the battery will last.

About 577 million household primary batteries (non rechargeable) batteries have been sold in the United Kingdom in 1998. They are used in a wide range of everyday devices like flashlights, radios and electric toys. Nickel Cadmium (NiCd) batteries are also common in households, in equipment such as power tools, camcorders, computers phones and mobile phones (there is a separate fact sheet on mobile phones). A dry battery requires fifty times more energy than it overlooks.

There have always been difficulties with recycling technology for general (non-rechargeable), as efficient separation and collection of many different types of batteries is difficult. The area of UK has now eliminated mercury from their own products, although a small number of batteries containing mercury are still imported from abroad. Check with the battery manufacturer to see if they are operating a system of recycling or recovery. This is particularly needed for battery NiCd s because they are the most dangerous type of battery in the house.

Laptop batteries: how it all began?

Welcome to a laptop battery specialist
of the Apple Laptop Battery   First post by: www.itsbattery.com

In the third millennium the laptop has become number one device extensively deployed by students, businessmen, tourists etc. Since it is portable, it can be taken on board an airplane to watch films or send/get messages from co-workers or business partners. However, the laptops cannot run day and night. Sometimes the laptop battery needs re-charging. Barely has any user thought about the first laptop batteries and their power.

In fact, the laptop battery has an exciting history. They have already come along way, but they still have a long way to go to perfection. When we think of laptop batteries such as apple PowerBook G3 Battery, Apple PowerBook G4 Battery, Apple PowerBook G4 15 inch Battery, Apple A1012 Battery, Apple M8511 Battery, Apple M8244 Battery, Apple A1079 Battery, Apple A1078 Battery, Apple A1148 Battery, Apple M6091 Battery, many of us think about the rechargeable ones that are deployed now. Yet, several decades ago AA batteries were extensively deployed in laptops. It took a great many AA batteries to run a laptop. Moreover, it could not run for long. Some people remember the heavy lead acid based batteries that did not only last long, but also made a laptop extremely heavy.

Since then the production of laptop batteries has been modified. Lighter nickel cadmium batteries (NiCd) superseded lead acid based ones. Yet, these batteries were not deployed much, since nickel metal hydride batteries (also known as NiMH) appeared. They lasted longer and were lighter. Their drawback was that they possessed the so-called memory defect. If the NiMH laptop battery had not discharged to the fullest, it remembered it and generated less power than it should do.

When lithium ion batteries (LiON) appeared on the IT market, customers saw a tremendous advancement in laptop batteries production. These batteries are much lighter if compared to other batteries and do not produce any memory defect. They are installed in laptops of the next generation.

Even though LiON batteries run non-stop for several hours, they require re-charging. Because more and more people buy laptops annually, the demand for longer lasting batteries is speedily increasing. Certainly, there will be improvements until batteries that never go dead are made. Regardless of the purpose you turn on your portable PC for, you know that you require a battery with a longer life. You need to know the battery will not go dead when you need your portable computer most of all.

Laptop battery is its flexibility

Welcome to a laptop battery specialist
of the Apple Laptop Battery   First post by: www.itsbattery.com

Laptop battery is its flexibility and stability of the fundamental, mainstream notebook standard rechargeable battery system. Rechargeable battery system includes rechargeable batteries and power management systems. The laptop battery is also embodied an important part of portability.

Batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel Cadmium Ni-Cd, Ni-MH Ni-MH, lithium Li.

Is the first laptop to use Ni-Cd nickel-cadmium batteries, as battery technology was not advanced enough, so a lot of nickel-cadmium batteries with the shortcomings of headache, such as: bulky, heavy weight, small capacity, short life, memory effects, etc.. So basically the current nickel-cadmium batteries have been eliminated, the following detailed description is not it.

Then began to use nickel-metal hydride notebook (NlMH) battery that has a good cost performance and higher power, while "nickel-hydrogen battery is one of the most environmentally friendly battery, pay attention to environmental protection are strongly promoting the use of state nickel-metal hydride battery, as it is easy recycling, and have the least damage to the environment. But NiMH batteries with lithium Xiangbi, or have some disadvantages. charging time is long, the weight of heavy, Rong Liang also smaller than the Li Dian, the battery lasts discharge time Taiduan, there is memory effect, its memory even without the nickel-cadmium batteries so much, but still need to discharge, the user must be exhausted after the charge.

Ni-MH battery lithium ion quickly (Li-ion) battery replacement. Lithium will have a long time ago and began its use is not safe, there is often in charge when burning, burst, and this may be because the lithium element too active reason. Then there is the improved lithium-ion batteries such as Apple A1175 Battery, Apple A1185 Battery, Apple M9324 Battery, Apple M8403 Battery, Apple M7318 Battery, apple PowerBook G3 Battery, Apple PowerBook G4 Battery, Apple PowerBook G4 15 inch Battery, Apple A1012 Battery, lithium element added to inhibit the active ingredients, so that lithium truly achieve a safe, efficient, convenient, and also followed the old lithium eliminated. Distinction between them is simple, the label from the battery can be identified lithium as Li, lithium-ion battery Li-ion. Now, the notebook uses the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery energy storage density, charge, and continued to discharge at any time a long time, usually about 3 hours. The size of the battery capacity from the marked mAh (milliamp hours) to determine the value, such as the 3000mAh, 4000mAh and so on greater value, the greater the capacity of the battery.

Of course there are defects in lithium-ion batteries, such as charge and discharge times of high prices and little more. Lithium battery charging and discharging of the number of only 400-600 times, specially modified products, but many times 800. Charge a per day basis, the best lithium batteries, but also more than two years. The NiMH rechargeable battery can reach 700 times more than some quality products to charge and discharge up to 1,200 times, such a comparison, Ni-MH battery live longer than lithium batteries, and NiMH batteries than the lithium battery prices much lower. Hence, there is no perfect laptop battery.

Most common brands of laptop batteries for the square. The market also has a small number of ultra-thin notebook using cylindrical batteries, such as SONY 505 series, Toshiba PROTEGE series. Battery weight varies according to materials and models, such as volume and shape of the same nickel metal hydride and lithium, but a difference of a lot of weight.

The size of the capacity marked mAh from the battery to determine its Chinese name is mAh. MA-hour size is directly related to the use of laptop time, but can not be generalized. Battery life notebook configurations with a great relationship, for example to speak, HP 6100 notebook with a PIII-M, MOBILITY RADEON graphics cards and many other energy saving technology hardware, with the 4000mAh battery, use the time up to 4 hours. Toshiba desktop CPU with 1800, although with a 4500mAh battery, use the time to 3 hours only. To meet the needs of the general going out to work. This also shows that the notebook is not only mAh battery related hardware, energy-saving technologies is very important.

Today, editor from itsbattery.com write this blog post to inform you how to use a laptop battery, and prolong your life.

May be you are now have a laptop or more, but how many tips are you have? How to take care laptop battery, if you use a laptop ac adapter to connect laptop for long time? These questions seems not serious, but they are actually affect laptop battery's life. Are you want to get a long time laptop? OK, let's learn how to use laptop!

1. Battery Scheme

Most laptops has the function of automatic frequency reduction, this function's advantage is prolong the laptop battery using time. The users of Celeron CPU based laptop might puzzled, their laptops don not have this function, So is it have no way to save power? The CPU is just one part of the save power union, actually, The power consuming parts are: LCD > CPU(full speed) > graphics card > WLAN card > CPU fan. That to say, except the CPU, we can also maximumly reducing power consumption from the other parts.

If you are a Windows xp user, you can find the power management options in the Windows XP control panel. Choosing "power using scheme", then setting LCD screen in idle 10 minutes to close, and set the disk above 15 minutes. Because the momentary boot disk requires a certain power, and frequently start or stop will damage the disk. Of course you can close the screen manually, most laptop can do this by FN function key and F3 key.

The above are the way to save laptop battery power through Setting LCD and disk closing time. if you want to further saving battery power, you need to adjust the operation of the system state, But this is not a Windows XP operate system can done. For example, The Thinkpad laptop have a self-contained battery management software. General laptop screen will provide 8 level brightness adjusting, although the brightest state can get the best visual effect, but it was very, very power consumption. So, when edit the document or some other common application, the screen brightness should adjusted to the 7 level or lower 6 level appropriate. Meanwhile, the CPU can also set up to best battery performance, CPU fan operation state set up to "equilibrium" more laptop battery power saving. Be aware of some laptop have no battery management software (because they have no built-in power management chips), but we also can use common battery monitoring software to manage the laptop battery such as Compaq EVO N620C Battery, Compaq Presario 1200 Battery, Compaq Presario 1800 Battery, Compaq Presario 700 Battery, Compaq Presario 900 Battery, Compaq Presario 1700 Battery, Compaq Armada E500 Battery, Compaq EVO N100 battery, Compaq Evo N1020V battery, Compaq Evo N1000C battery, Compaq Evo N115 battery. BatteryMon was a good common battery monitoring software.

For example, we test a battery. When it runs at full speed played on DVD, the laptop battery life is only 2 hours and 37 minutes. If the laptop battery optimized solutions use, its life can reach to about 3 hours and 17 minutes. we can see the ascension was very obvious. These are setting up laptop screen brightness, laptop CPU speed, laptop fan speed to save battery power. Replacement lenovo thinpad ac adapter.

2. The correct laptop battery charging methods

Most laptop user tend to charge to laptop battery when the battery power less than 100%, but itsbattery.com 's editor will tell you that's a bad case of laptop using method. If you do this method for long time, your laptop battery's life will be shorten quickly! So, supply battery advise you to charge battery after the battery power lower than 10%, but do not let it lower than 3%. In order to follow the method, you need to config the battery power alarm. For best use, we can set it up to lower than 10%, if you set up lower than 3%, the laptop can not turn on to the next time. Most laptop battery management software are default setting up to charge when power below 96%, but this chargement will harm to your laptop battery. So, you need to change the config of the charging set. In addition, it's useful to turn off your laptop when you charging it, that's can prolong your laptop battery life.

3. Is Discharge necessary?

If your in using for a long time and power greatly reduced, you can try to depth discharge to save it. This is a "dead straws when" method, do it only if nothing you can do. The best discharge method is constantly running the laptop program. When battery power is below 3% then restart laptop and enter BIOS to vacancy run until laptop automatic power off. After depth discharge, Then use a battery charger or adapter to keep a depth charging, the charging time need to over 8 hours, but not more than 12 hours, Keeping this way, your laptop lithium battery will restore some power electric.

Solid State Drives - SSD Facts You Should Know

Welcome to a laptop battery specialist
of the Compaq Laptop Battery   First post by: www.itsbattery.com

If you're interested in the latest technology, then solid state drives have probably been on your radar for awhile now. Also, known as an SSD, these drives are being hyped as the next wave of greatness for laptops and for computers in general.

The big question, however, is do they deliver on all of these promises or, like so many grand advancements promoted in the past, just overhyped.

To answer those questions, we first need to learn a little bit more about these drives. Then we'll delve into how they stack up to their promises.

A Little Background

Basically, these drives aren't new but they made a huge splash in 2007 at the Consumer Electronic Show held in Las Vegas. They were heralded as the solution to many problems facing those of us who love portable computing.

Basically these devices are types of hard drives which do not rely on magnetic media for their memory storage. Instead, they use semiconductors much like flash memory drives already do. In fact, both of these storage devices use similar non-volatile memory chips.

However, the main difference between the two is that the solid state drive is not used as an external memory storage system like flash drives. They are built to be installed internally in place of a traditional hard drive.

If you're wondering why using SSD's would be a good idea, there are several advantages being promoted by industry insiders. This is where most of the promises come into the picture.

Basically, these drives are considered great inventions because they are believed to deliver three amazing benefits: reduced power usage, faster access to memory, and improved reliability. All of these benefits are a result of the differences in the way solid state drives and traditional hard drives work.

Most of us have at least a basic understanding of how our hard drives work. Inside them are spinning magnetic platters where everything we do on our computers is saved.

To work though, they rely on drive motors to move them. If anything happens to those motors or to the drive heads, then our hard drive ceases to function correctly and we'll end up shopping for a new laptop or desktop.

These alternative drives don't have all of those extra parts. Everything is done through Flash memory chips and most of us know that the portable Flash memory we use in our cameras and other storage devices does a pretty good job of saving quickly and of working when we need it to.

As you can imagine, having a drive that uses less power, is less vulnerable to damage, and is able to retrieve data faster would be a dream for most laptop owners. That's why it's important to look at whether or not these drives really deliver on these promises.

Do Solid State Drives Deliver?

Many laptop manufacturers have already released products contains solid state drives so there are some on the market which allow us to get an idea of how they are stacking up to these promises. First, we can look at the promise of quick data access.

Unfortunately, there have been some problems with customer satisfaction in this area because of the hype. People are promised the moon and are disappointed when the drive can't live up to their elevated expectations.

Evidence has shown that these drives do wonderful when you're reading average size files. You'll be able to access them quickly. However, if you're working with large files or trying to save large files, you won't see those fast speeds.

Now remember these drives are still in their infancy in terms of this type of use so that doesn't mean these problems won't be corrected down the line.

Another huge promise is improved battery ( such as Compaq Armada M700 Battery, Compaq EVO N400c Battery, Compaq EVO N410c Battery, Compaq EVO N600C Battery, Compaq EVO N610C Battery, Compaq EVO N620C Battery, Compaq Presario 1200 Battery, Compaq Presario 1800 Battery, Compaq Presario 700 Battery, Compaq Presario 900 Battery ) life for laptops because of the reduced power requirements. For one, this promise could never really deliver because the hard drive isn't what uses up most of your laptop's battery in the first place.

The screen, the RAM, and your CPU are doing most of that for you. Generally, you're only talking about a 5% improvement in battery life and that's not much of a bargain considering how much these drives add to the price of a laptop.

Finally, we can look at reliability. Since the drives haven't been available that long, we really need more time to evaluate this claim. However, we do know that unlike traditional hard drives which can be written on indefinitely. Solid state drives can only a certain number of times depending on the technology used.

This is still sufficient for most needs but given the costs , and whilst these writes will

Only time will tell if these problems can be rectified so that solid state drives can truly live up to everything they are promised to be.
