Always switch the device off and disconnect the charger
before removing the battery.
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.
Always try to keep the battery between 15°C and 25°C
(59°F and 77°F). Extreme temperatures reduce the
capacity and lifetime of the battery. A device with a hot or
cold battery may not work temporarily. Battery
performance is particularly limited in temperatures well
below freezing.
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.
