■ Battery information
Li-Ion battery BLB-2 is the 
manufacturer-approved 
rechargeable battery is available for 
your phone.
Charging and discharging 
the battery
• Your phone is powered by a 
rechargeable battery.
• Never remove or replace the 
battery when the phone is 
connected to the charger.
• 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.
• 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.
• Temperature extremes will affect 
the ability of your battery to 
charge: allow it to cool down or 
warm up first.
