Laptop rechargeable battery is not eternal. The duration of the operation of the ACB directly depends on the number of charge cycles. The larger the number of times the battery is charging, the less its term "Life." Therefore, that the battery serves longer, the battery should be used as less as possible.
In case the laptop is designed exclusively for home use, you must remove the battery. Before you start, you need to turn off the laptop. You should make sure that the laptop completely turned off, and did not switch to "sleeping"mode (hibernation mode), which sometimes occurs on some devices. The operating system must complete the work. You can not remove the battery if the laptop is connected to the 220V network. The power supply cable must be disconnected from the laptop.The work of the laptop without a battery will allow the battery to stop for quite a long time, or rather as much as the charge-discharge cycles are laid in the rechargeable battery.
