■ 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.
