Storing a Battery Pack
Ä
CAUTION: To prevent damage to the battery pack, do not expose it to
high temperatures for extended periods of time.
If the notebook will be unused and unplugged for more than
2 weeks, remove and store the battery pack.
High temperatures accelerate the self-discharge rate of a stored
battery pack, so place it in a location that is cool and dry.
Before using a battery pack that has been stored for one month or
more, calibrate it. This insures that the battery information
displayed by your notebook is accurate.
