20. Battery and charger information
Your device is powered by a rechargeable battery. The battery intended for use with
this device is BL-5B. This device is intended for use when supplied with power from
the following chargers: AC-3, AC-4, AC-5, AC-8 or DC-4 chargers and CA-44 charging
adapter. 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.
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 battery.) This might
happen, for example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
