- Laptop-Akku do not need to be fully charged after all the power is used up
Nowadays, laptop batteries are all lithium batteries. For lithium batteries, it is useless to charge them for a long time after the batteries are fully used up, and it is even harmful. Because lithium batteries do not have the so-called "cache effect", only early nickel batteries have this feature. The life of laptop batteries is generally only related to human damage or natural life. Basically, the life of the battery is fixed, and the number of charge and discharge times of 300-600 times is generally used for 2 years. - Daily use
Some people say: If you often use laptop batteries, then you should try to fully charge the laptop every time you unplug the power supply. And if the battery is still a little bit used, and you have time to use the computer, try not to plug in the power cord first, and wait until your laptop is completely out of power before plugging in the power cord.
Some people also say: Whether to unplug or not depends on the actual use: It does not harm the battery if it is not unplugged while connected to a DC power source, because the battery will not receive any power injection after it is fully charged, and all the power will be directly transferred to the laptop's power supply system. However, when the laptop is running at high speed and the internal part is overheated, it is best to remove the battery, otherwise it will be harmful.

You should try to avoid waiting for the battery to be completely exhausted before charging, because this will put a lot of pressure on the battery and cause damage. A more feasible approach is to charge when the remaining power is about 20-30%. In fact, the number of times the laptop's lithium battery can be "used up/charged" is limited. Using up all batteries and then charging will only greatly shorten the battery life. At the same time, the battery should be charged in a relatively dry place, and attention should also be paid to heat, which is the enemy of the battery.
Tips: The use of mobile phone batteries is different from that of laptop batteries. Many people may judge based on their experience in using mobile phone batteries and think that laptop batteries should also be completely used up before charging. This idea is wrong. - Related brand recommendationDELL.ASUS.LENOVO.SAMSUNG.SONY.PANASONIC.OTHER.HUAWEI
