Storing a Battery Pack
If a notebook will be unused and not connected to external
power for more than 2 weeks, remove and store the battery pack.
CAUTION: To prevent damage to a battery pack, do not expose it
to high temperatures for an extended time.
High temperatures accelerate the self-discharge rate of a stored
battery pack. To prolong the charge of a stored battery pack,
store it in a cool, dry place within the following temperature
ranges.

puncture a battery pack or short the contacts on a battery pack. Do

(140°F) or dispose of a battery pack in water or fire.
When a battery pack has reached the end of its useful life, do not
