Charging and discharging
Your device is powered by a rechargeable BL-4C standard 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.
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 59°F and 77°F (15°C and 25°C). 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. They may also explode
if damaged. Dispose of batteries according to local regulations. Please recycle
when possible. Do not dispose as household waste.
