A rechargeable battery powers your phone.
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 that 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.
