5. Battery and charger information

This device has an internal, nonremovable, rechargeable battery. Do not attempt
to remove the battery from the device as you may damage the device. This device
is intended for use when supplied with power from the following chargers: AC-3,
AC-4, AC-5, and DC-4. The exact charger model number may vary depending on
the type of plug. The plug variant is identified by one of the following: E, EB, X,
AR, U, A, C, or UB. The battery can be charged and discharged hundreds of times,
but it will eventually wear out. Recharge your battery only with Nokia approved
chargers designated for this device. Use of an unapproved charger may present a
risk of fire, explosion, leakage, or other hazard.
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.
