15 Reference information
• BATTERY INFORMATION
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, buy
a new battery. Use only Nokia approved batteries, and recharge your battery only
with Nokia approved chargers designated for this device.
Unplug the charger from the electrical plug and the device when not in use. Do not
leave the battery connected to a charger. Overcharging may shorten its lifetime.
If left unused, a fully charged battery will lose its charge over time. Temperature
extremes can affect the ability of your battery to charge.
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.
