only with the chargers approved by the
manufacturer.
Unplug the charger when not in use. Do
not leave the battery connected to a
charger for longer than 10 days, since
overcharging may shorten its lifetime. If
left unused a fully charged battery will
discharge itself over time.
Temperature extremes can affect the
ability of your battery to charge.
Use the battery only for its intended
purpose.
Never use any charger or battery which is
damaged.
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 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. A
phone with a hot or cold battery may
temporarily not work, even when the
battery is fully charged. Batteries
