Battery information
Li-Ion battery BLB-2 is the manufac-
turer-approved rechargeable battery
is available for your phone.
Charging and
discharging the battery
• Your phone is powered by a re-
chargeable battery.
• Never remove or replace the bat-
tery when the phone is connected
to the charger.
• Note that a new battery’s full per-
formance 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 short-
er 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 charg-
ers approved by the manufacturer.
• When a charger is not in use, dis-
connect it from the power source.
Do not leave the battery connect-
ed to a charger for longer than a
week, since overcharging may
shorten its life. If left unused a ful-
ly charged battery will discharge
itself over time.
