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 operating 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.
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.
