Battery information
Your phone is powered by a rechargeable battery.
The operation and the lifetime of the battery are greatly affected by 
how you handle the battery. Take good care of the battery and 
follow the guidelines presented below.
Charging and discharging the battery
• 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 (talk-
time and standby time) is noticeably shorter than normal, it is 
time to buy a new battery.
• Use only batteries approved by the phone manufacturer and 
recharge your battery only with the chargers approved by the 
manufacturer.
• When a charger is not in use, disconnect it from the power 
source. Do not leave the battery connected to a charger for 
longer than a week, since overcharging may shorten its life. If 
left unused a fully charged battery will discharge itself over time.
• For good operation times, discharge the NiMH battery from time 
to time by leaving your phone switched on until it turns itself off. 
Do not attempt to discharge the battery by any other means.
• Temperature extremes will affect the ability of your battery to 
charge: allow it to cool down or warm up first.
