Unplug the charger from the
electrical plug and the device
when not in use. Do not leave
a fully charged battery
connected to a charger, since
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
lifetime of the battery. A
device with a hot 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
