Asus C21N1347 laptop battery maintenance precautions:Some clients use new batteries for less than 2 years or even less than 1 year. This is because the wrong way of using them will significantly reduce the service life of the battery. The following are something to focus on when using laptop batteries:
- Avoid running out of battery power: This approach will destroy the reactants of the lithium battery, thereby reducing the life of the lithium battery.
- Avoid using the battery in a high-temperature environment: High temperature will destroy the chemical balance in the battery, causing some reactants to undergo side reactions, thereby reducing the charging speed and greatly shortening the battery life. In serious cases, it may also cause an explosion.
- Try to use an external power source, if not necessary, avoid using the battery alone.
- When the notebook is not used for a long time, it is recommended that you unplug the battery and store the battery separately.
- Before storing the battery separately, please ensure that the battery power is no less than 80%, and try best to charge the battery every month or so.
- Use the official charging application "Asus Battery Health Charging" to extend Asus C21N1347 battery life.
