Important Battery Information
• Use only batteries and chargers approved by the
phone manufacturer.
• 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; overcharging may
shorten its life.
• If left unused, a fully charged battery may completely
drain (discharge) in 1 - 4 weeks.
• Never use any charger or battery that is damaged or
worn out.
• Use the battery only for its intended purpose.
• Do not short circuit the battery. Accidental short cir-
cuiting can occur when a metallic object (e.g. coin,
clip or pen) causes direct connection of the two termi-
nals 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, reduces
the capacity and lifetime of the battery. Always try to
keep the battery between 41°F and 95°F (5°C and
35°C). A phone with a hot or cold battery may tempo-
rarily not work (or charge) even if the battery is fully
charged. NiMH battery performance is particularly
limited in temperatures below 14°F (-10°C).
