7. Battery information

■ Charging and
Discharging
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.
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 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!
Dispose of batteries according to
local regulations. Please recycle
when possible. Do not dispose as
household waste.
