This section provides information about
your phone batteries, enhancements,
chargers, safety guidelines and
technical information. Be aware that
the information in this section is
subject to change as batteries,
chargers, and enhancements change.
■ Batteries and chargers
Your device is powered by a
rechargeable battery. The full
performance of a new battery is
achieved only after two or three
complete charge and discharge
cycles. 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, buy
a new battery. Use only Nokia
approved batteries, and recharge your
battery only with Nokia approved
chargers designated for this device.
Unplug the charger from the electrical
plug and the device when not in use.
Do not leave the battery connected
to a charger after the battery has
finished charging. Overcharging may
shorten its lifetime. If left unused, a
fully charged battery will lose its
charge over time. Temperature
extremes can affect the ability of
your battery to charge.
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 59°F and 77°F
(15°C and 25°C). 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.
