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, and 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 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.
