• (NiMH batteries only) 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 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.
• 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 59º F and 77º F (15º C and 25º 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 tempera-
tures below 14º F (-10º C). Li-Ion batteries’ performance is
particularly limited in temperatures below 32º F (0º C).
• Do not dispose of batteries in a fire!
• Batteries must be recycled or disposed of properly. Must
not be disposed of in municipal waste.
