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.
