16. 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.
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.
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.
