• Batteries and chargers
For information about charging and recharging your phone battery, see
“Charge the battery” on page 8.
Use only batteries approved by the phone manufacturer. Recharge your
battery only with the chargers approved by the manufacturer.
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 will
eventually wear out. When the operating time (talk-time and standby
time) is noticeably shorter than normal, it’s time to buy a new battery.
When a charger is not in use, disconnect it from the power source. Don’t
leave the battery connected to a charger for longer than a week, since
overcharging may shorten its life. If left unused a fully charged battery
will discharge over time.
For good operation times, discharge the battery from time to time by
leaving your phone switched on until it turns itself off (or by using the
battery discharge facility of any approved accessory). Don’t attempt to
discharge the battery by any other means.
Temperature extremes will affect the ability of your battery to charge.
Allow it to cool down or warm up to room temperature before charging.
When the battery is running out of power and only a few minutes of talk
time remain, a warning tone is emitted and Battery low appears on
screen. When no more talk time is left, Recharge battery appears on
screen, a warning tone sounds, and the phone switches off.
Use the battery only for its intended purpose.
Never use any charger or battery that is damaged or worn out.

Reference information
Don’t short circuit the battery. Accidental short circuits can occur when a
metallic object (coin, clip, or pen) is touched to the + and - terminals of
the battery. Shorting the terminals together may damage the battery or
connecting object.
Don’t leave the battery in hot or cold places, such as in a closed car in
summer or winter conditions. Doing so 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 disable, even
when the battery is fully charged. NiMH battery performance is limited in
temperatures below -10
°
C (14 F). Li-Ion battery performance is limited in
temperatures below 0 C (32 F).
Batteries must be recycled or disposed of properly. Do not dispose of them
in municipal waste.
Do not dispose of batteries in a fire!
