7. 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 48 hours,
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.
