• Using batteries and chargers
For charging and recharging your phone battery, see “Charge your battery”
on page 5.
Use only batteries approved by the phone manufacturer and 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 it will
eventually wear out. When the operating time (talk-time and stand-by
time) is noticeably shorter than normal, it is time to buy a new battery.
When a charger is not in use, disconnect it from the power source. Do not
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 itself over time.
For good operation times, discharge NiMH batteries 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 available for your
phone). Do not 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 first.
When the battery is running out of power and only few minutes of talk
time remain, a warning tone is heard and Battery low is briefly displayed.
When no more talk time is left, the phone will beep three times and Recharge
battery is displayed. The phone then switches itself off.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged or worn out.

Reference information
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 back of 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 59
° F and 77° F (15° C and 25° C).
A phone with a hot or cold battery may temporarily not work, even when
the battery is fully charged. NiMH batteries performance is particularly
limited in temperatures below 14
° F (-10°C). Li-Ion batteries performance
is particularly limited in temperatures below 32
° F (0° C).
Batteries must be recycled or disposed of properly. Must not be disposed
of in municipal waste.
Do not dispose of batteries in fire!
