■ 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.
