16. Battery and charger information
Your device is powered by a rechargeable battery. The battery intended for use with this
device is BL-5C or BL-5CA. This device is intended for use when supplied with power from
the following chargers: AC-3 or AC-3U. 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 of an
unapproved battery or 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 appears on the display or before any calls can be
made.
