Battery Information; Charging And Discharging - Nokia 5500 Sport User Manual

16. 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
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 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
