the charging indicator appears on the display or before
any calls can be made.
Always switch the device off and disconnect the charger
before removing the battery.
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 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.
