following chargers: AC-3, AC-4, AC-5,
AC-8, 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
significantly 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.
