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, flush your skin or eyes immediately with water,
or seek medical help.
