19. 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,
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 start the charging.
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 a few
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
