Battery Problems and Solutions
Problem
Battery charge
doesn't last as long
as expected.
Battery packs are
warm to the touch
after charging.
Store the battery pack in a cool, dry place when not in use.
NOTE:
High temperatures reduce the life of the battery pack and cause it
to lose its charge more quickly. If you are storing the battery for
less than one month, the recommended storage temperature is 32
F to 122 F (0 C to 50 C); for no more than three months, the
recommended temperature is 32 F to 104 F
(0 C to 40 C); for an unlimited time, the recommended
temperature is 32 F to 86 F (0 C to 30 C).
