The current laptop is a lithium battery, and a battery-charging protection system is integrated on the motherboard, which automatically cuts off the charging power when the battery is full. In addition, when the battery is filled, the computer will automatically use the power supply instead of using the battery. Lithium battery life is calculated by a complete charge and discharge, if you fear that the battery is overcharge, so often the batte
