17. Battery information

Charging and discharging

Your device is powered by a rechargeable battery. The battery can be charged and
discharged hundreds of times, but it will eventually wear out. When the talk and standby
times are noticeably shorter than normal, replace the battery. Use only Nokia approved
batteries, and recharge your battery only with Nokia approved chargers designated for
this device.
If a replacement 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.
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.
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.
Use the battery only for its intended purpose. Never use any charger or battery that is
damaged.
