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
