Before we start this topic, I want to ask how much do you know about laptop battery? Because as we all know, most of laptop users leave the battery in their laptop and do not pay any other extra attention since they get begin to use laptop. They will not consider the charge-discharge of the battery. They do not know that the battery life is closely related to its charge cycle. But actually, you need to charge battery fully to 100% and drain it to shutdown automatically during the whole process of using laptop.

If you find that your laptop battery can not be charged fully but it has stopped charging, then you may need to calibrate the battery indicator. And calibrating in time will help you active the battery and the battery may gain a part of loss capacity.

In the earlier years, laptop batteries had serious memory effect. Later, memory effect gradually disappeared in modern batteries. But in fact the lithium batteries still have a little memory effect. The material of this kind battery is very sensitive to the environment like temperature. And after a certain time, the battery will be aging. Besides, the natural wear and tear and inadequate maintenance will speed up the battery aging.

After hearing this, now do you think the laptop battery is so damageable that it is difficult to be maintained? Please do not worry. Today the lithium batteries are well-designed. They have a very good protection circuit to prevent overcharge and over discharge. You just charge your battery without controlling the charge.
