Unplug the charger from the electrical plug and the device
when not in use. Do not leave a fully charged battery
connected to a charger, since overcharging may shorten
its lifetime. If left unused, a fully charged battery will lose
its charge over time.
Use the battery only for its intended purpose. Never use
any charger or battery that is damaged.
Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object such as a coin,
clip, or pen causes direct connection of the positive (+)
and negative (-) terminals of the battery. (These look like
metal strips on the battery.) This might happen, 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 59°F and 77°F (15°C and 25°C). A
device with a hot or cold battery may not work
temporarily, even when the battery is fully charged.
