Maintenance method of notebook battery:
1, there is no need to deliberately ensure that the battery will be charged every time it is discharged. Today's notebook batteries are all lithium batteries. For lithium batteries, it is useless or even harmful to charge with photovoltaic cells for a long time.
2. The deep charge and discharge under the control of the protection circuit can be carried out once in a while to correct the battery power statistics, but this will not improve the actual capacity of your battery.
3. Batteries that have not been used for a long time should be placed in a cool place to weaken the internal passivation reaction.
4. The protection circuit can't monitor the self-discharge of the battery. Batteries that have not been used for a long time should be charged with a certain amount of electricity to prevent the battery from being damaged by excessive self-discharge during storage.
