■ 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. 
Use only Nokia approved batteries, and recharge your battery only with 
Nokia approved chargers designated for this device.
Check the model number of any charger before use with this device. This 
device is intended for use when supplied with power from the ACP-12 
charger.
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.
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,
