Taking good care of your battery
Having a battery fully charged and the laptop plugged in is not harmful. We suggest that you remove the battery when the hardware gets too hot.
Partial discharges to capacity levels of 20~30% and frequent charges are recommended while a full discharge followed by a full charge is not.
To store a battery for long periods of time, its charge capacity should be around 40% and it should be stored in a place as fresh and dry as possible.
