Battery Information
The following manufacturer-approved rechargeable batteries are

Charging and Discharging the Battery
• Your phone is powered by a rechargeable battery.
• 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 (talk-time and 
stand-by 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.
