why battery last shorter and shorter

Have you ever found your laptop battery last shorter and shorter? Have you been concerned about the dell YD626 battery and dell 312-0393 battery as it’s original battery of your laptop accessory? The answer is pretty sure. Every laptop

user wish they have a perfect battery which can keep longer and cheaper. And I am one of those who are really caring about the laptop battery’s life span. And many friends are always complained about the laptop battery.

Take this dell Latitude D820 battery for example, it has used for half a year. But its owner found that it’s hard to keep it for two hours as it’s said at the very beginning. So what’s the matter？Most people take it for granted that all the battery has the same situation. But have you ever quested why it has reduced the performance of the laptop? Here will show you more information about this phenomenon.

In general, battery, as a consumable material, has self-discharge electronically properties that is difficult to overcome. During the using and storing, laptop battery constantly engaged in the internal electronical reaction. And dell Latitude D820 battery capacity will gradually decrease. At the same time, the positive and the negative of the laptop will continue to fall off, get aged as well as the dendrites grows. As a result, the laptop battery’s capacity reduced. Meanwhile, its performance decreased after a period of time.

I used to dissected the dell battery such as dell 312-0386 battery, dell PC764 battery, dell TD175 battery, dell Latitude D830 battery, dell MM165 battery and found that some white external corrosion flow outside. This is because the positive and the negative active material ration formula are unreasonable in the event of the electrochemical redox reaction. Then, this condensation will be greatly reduced battery performance. And the capacity decreased significantly reduces charge and discharge cycle life of the battery.

Most laptop battery cells are constituted of a battery pack as this dell Latitude D620 battery, it’s made of six batteries. The six batteries are connected by a few of charge and discharge detection circuit protection. When our laptop battery has strong dendrite, we can change the battery cell to repair its life time. It’s really simple for the experts. Personally speaking, it should be done under the professional officers. Otherwise, you will ruin your laptop battery. This is not kidding if you want a good laptop battery.
