7. 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, buy a new battery. Contact the authorised service facility for replacement battery. Do not attempt to do it yourself. Use only Nokia approved batteries, and recharge your battery only with Nokia approved chargers designated for this device. A few practical rules on enhancement operation • 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. Copyright © 2005 Nokia. All rights reserved. 122
