Battery Packs

Storing a Battery Pack

If a notebook will be unused and unplugged for more than
2 weeks, remove any battery packs from the notebook and store
them separately.
Ä
CAUTION: To prevent damage to a battery pack, do not expose it to
high temperatures for extended periods of time.
High temperatures accelerate the self-discharge rate of a stored
battery pack. To prolong the charge of a stored battery pack, place
it in a cool, dry place.
Use the following table to estimate how long you can safely store
a battery pack. The storage times provided are based on a battery
pack that contains 50 percent of a full charge. A fully charged
battery pack can be safely stored for longer times; a battery pack
containing a lower charge can be safely stored for less time.
Calibrate a battery pack that has been stored for 1 month or more
before using it.
