Battery information 11. 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 operating 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 performance is particularly limited in temperatures well below freezing. Copyright © 2005 Nokia. All rights reserved. 41

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 operating 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 performance is particularly
limited in temperatures well below freezing.
