battery connected to the AC charger, since
overcharging may shorten its lifetime. If left unused, a
fully charged battery will lose its charge over time. If
the battery is completely discharged, it may take a few
minutes before the charging indicator appears on the
display or before any calls can be made.
Use the battery only for its intended purpose. Never
use any charger or battery that is damaged.
Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object such as a
coin, clip, or pen causes direct connection of the
positive (+) and negative (-) terminals of the battery.
These look like metal strips on the battery. This might
happen, for example, when you carry a spare battery
in your pocket or purse. Short-circuiting the terminals
may damage the battery or the connecting object.
Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce
the capacity and lifetime of the battery. Always try to
keep the battery between 15° C and 25° C (59° F and
77° F). A device with a hot or cold battery may not
work temporarily, even when the battery is fully
charged. 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.
Dispose of batteries according to local regulations.
