• 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 the NiMH battery from time to
time by leaving your phone switched on until it turns itself off. 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, Battery
empty is displayed and a warning tone is sounded and the phone
switches itself off.
Using the Batteries
• Use the battery only for its intended purpose.
• Never use any charger or battery which is damaged or worn out.
• 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 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. NiMH
batteries performance is particularly limited in temperatures below
-10°C (14 F). Li-Ion batteries performance is particularly limited in
temperatures below -0 C (32 F).
• Do not dispose of batteries in a fire!
Batteries must be recycled or disposed of properly.
Must not be disposed of in municipal waste!
