Laptop Battery Usage Tips

In science and technology, a battery is a device that stores energy and makes it available in an electrical form. It converts chemical energy into electrical energy, producing an electric current when connected in a circuit. The finished battery is an electrically connected group of cells (wired in series) that stores an electrical charge and supplies a direct current (DC). We usually call finished battery as battery pack and unfinished battery is called as cell.


2.How to classify the battery?

Batteries are grouped into following categories:

Alkaline battery

Zincic carbolic battery

Lead-Acid battery

nickel-metal-hydride

nickel-cadmium

Lithium battery

Li-ion battery

Li-polymer battery

Fuel cells

Solar cells

Other types of battery


3.What are the differences between Primary Battery and rechargeable battery?

A primary battery is not intended to be recharged and is discarded when the battery has delivered all of its electrical energy.

A rechargeable battery is a galvanic battery which, after discharge, is restored to the fully charged state by the passage of an electrical current through the cell in the opposite direction to that of discharge.


4.What causes short lifetime of battery? How to prolong the lifetime of battery?

1)Reason:

a.Charger or electro circuit can't be fit for the IBM Laptop Battery such as IBM ThinkPad T40 Battery, IBM ThinkPad T41 Battery, IBM ThinkPad T42 Battery, IBM ThinkPad T43 Battery, IBM ThinkPad R50 Battery, IBM ThinkPad R51 Battery, IBM FRU 08K8193 Battery, IBM 92P1060 Battery .

b.Overcharge and overdischarge, etc.

c.Battery can't comply with the charging requirement

2)Solution:

a.Use the original charger.

b.Charge the battery after it automatically powers off , then full charge the battery.

c.Avoid erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.


5.Why can't the battery be charged? How to solve this problem?

1)Reason:

a.The battery has no voltage.

b.There is problem with charger, as it has no output electric current.

c.Low charging efficiency due to external cause.

2)Solutions:

a.Test whether the charger has voltage and output electric current or not.

b.Check if the charger is well contacted with battery.

c.Activate the battery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)


6.What's the reason that causes battery with no voltage or low voltage? How to avoid this problem?

1)Reason

a.No voltage.

b.External shot circuit or overcharge, anti-charge

c.Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging.

2)Solutions:

a.Check if the battery is without voltage or electric current.

b.Avoid short circuit.

c.Avoid collision and pressure among batteries.

d.Charge the battery after it automatically powers off , then full charge the battery.
