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 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.
•
Unplug the charger when not in use.
•
Do not leave the battery connected to a charger
for longer than a week, since overcharging may
shorten its lifetime.
•
If left unused a fully charged battery will discharge
itself over time.
•
Temperature extremes can affect the ability of your
battery to charge.
•
Use the battery only for its intended purpose.
•
Never use any charger or battery which is
damaged.
•
Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object (coin,
clip or pen) causes direct connection of the +
and - terminals of the battery (metal strips on
the battery) for example when you carry a spare
battery in your pocket or purse. Short-circuiting
the terminals may damage the battery or the
connecting object.
•
Leaving the battery in hot or cold places, such as in
a closed car in summer or winter
