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 light is displayed.
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 damaged.
Important: Battery talk and standby times are estimates only and depend
on network conditions, features used, battery age and condition,
temperatures to which battery is exposed, and many other factors. The
amount of time a device is used for calls will affect its standby time.
Likewise, the amount of time that the device is turned on and in the
standby mode will affect its talk time.
