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.
