Battery and charger information

Your device is powered by a rechargeable battery. The battery intended for use with
this device is BL-4S. This device is intended for use when supplied with power from
the following chargers: AC-3. 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. Use only replacement batteries qualified with the device per the
IEEE-1725-2006 standard. Use of other batteries or chargers may present a risk of
fire, explosion, leakage, or other hazard.
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.
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 appears on the display or
before any calls can be made.
Always switch the device off and disconnect the charger before removing 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.
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 short-circuit the battery. Accidental short-circuiting can occur when a
metallic object such as a coin, clip, or pen causes direct connection of the positive
(+) and negative (-) terminals of the battery. (These look like metal strips on the
