4. Battery information
Your headset is powered by a rechargeable battery. Take good care of the battery
and follow the guidelines below.
Charging and discharging
•
Note that a new battery's full performance 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 operating time is noticeably shorter than normal, it is time to buy a new
battery.
•
Use only batteries approved by Nokia and recharge your battery only with the chargers
approved by Nokia. Unplug the charger when not in use. Do not leave the battery
connected to a charger for longer than a week, since overcharging may shorten its lifetime.
If left unused a fully charged battery will discharge itself over time.
•
Temperature extremes can affect the ability of your battery to charge.
•
For good operation times with NiMh batteries, discharge the battery from time to time by
leaving your headset switched on until it turns itself off. Do not attempt to discharge the
battery by any other means.
•
Use the battery only for its intended purpose.
•
Never use any charger or battery which is damaged.
•
Leaving the headset 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

•
Do not dispose of a battery in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose
