overcharging may shorten its lifetime.
If left unused, a fully charged battery
will lose its charge over time.
Always try to keep the battery between
15°C and 25°C (59°F and 77°F). Extreme
temperatures reduce the capacity and

or cold battery may not work temporarily.
Battery performance is particularly limited
in temperatures well below freezing.
Do not dispose of batteries in a fire as
they may explode. Batteries may also
explode if damaged.
Never use any charger that is damaged.

and depends on battery age
and condition and on temperatures to
which battery is exposed.
