10. 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.
This device has an internal, removable, rechargeable battery. 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.
To prolong battery life of NiMh batteries, discharge the battery
from time to time by leaving your device switched on until it
turns itself off. Do not attempt to discharge the battery by any
other means.
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

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 as they may explode.
Batteries may also explode if damaged. Dispose of batteries
according to local regulations. Please recycle when possible. Do
not dispose as household waste.
