Battery information

Charging and discharging

Your device is powered by a rechargeable battery. 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.
If a replacement 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.
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.
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.
Use the battery only for its intended purpose. Never use
any charger or battery that is damaged.

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.
Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce the
capacity and lifetime of the battery. Always try to keep
the battery between 15°C and 25°C (59°F and 77°F). A
device with a hot or cold battery may not work
temporarily, even when the battery is fully charged.
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. Dispose of
batteries according to local regulations. Please recycle
when possible. Do not dispose as household waste.
Do not dismantle or shred cells or batteries. In the event
of a battery leak, do not allow the liquid to come in
contact with the skin or eyes. In the event of such a leak,
