If a battery is being used for the first time or if the battery has
not been used for a prolonged period, it may be necessary to
connect the charger, then disconnect and reconnect it to begin
charging the battery. If the battery is completely discharged,
it may take several minutes before 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.
