Computer battery use and maintenance

1. When there is no external power supply, if the card in the PCMCIA slot is not needed at that time, it is recommended to unplug the card first to prolong the battery life.

2. Room temperature (22 degrees) is the most suitable working temperature of the battery, and the working environment with too high or too low temperature will reduce the service life of the battery.

3. When using the notebook computer in an environment that can provide a stable power supply, taking out the battery can prolong the service life of the battery. As far as ASUS notebook computer is concerned, when the battery is low, the charging circuit in the battery will automatically turn off, so it will not be overcharged.

4. It is recommended to correct the battery charge once every three months on average.

5. Try to reduce the number of times you use the battery.

The charge and discharge times of a battery are directly related to its life. Every time the battery is charged, it will take a step forward before retirement. It is recommended that you try to use an external power supply.

6. When using external power supply, take out the battery (excluding lithium battery).

Some users often plug in and out the power supply many times a day, and notebook computers are equipped with batteries, which will cause greater damage to the batteries. Because every time you connect an external power supply, it is equivalent to charging the battery once, and the battery naturally has no life (especially for nickel-hydrogen and nickel-cadmium batteries, but not for lithium batteries).

7. Recharge the battery after it is exhausted to avoid charging for too long.

Your notebook uses Ni-MH battery and Ni-Cd battery, so be sure to recharge it after the power is exhausted (the power is lower than 1%), which is the best way to avoid the memory effect.

8. Precautions for normal use

In normal use, it is necessary to prevent exposure, moisture, chemical liquid erosion and contact between battery contacts and metal objects.
