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.
