11. Battery information
This section provides information
about batteries, chargers, safety
guidelines and technical information.
Be aware that the information in this
section is subject to change as
batteries and chargers change.
■ Charging and
discharging batteries
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.
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 and its ability to charge.
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.
