8. Battery information
■ Charging and
Discharging
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 conditions, will
reduce the capacity and lifetime of
the battery. Always try to keep the
battery between 15°C and 25°C
(59°F and 77°F). A phone with a hot
or cold battery may temporarily not
work, even when the battery is fully
charged. Batteries' performance is
particularly limited in temperatures
well below freezing.
Do not dispose of batteries in a fire!
Dispose of batteries according to
local regulations (e.g. recycling). Do
not dispose as household waste.
