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.
Do not dispose of batteries in a fire as they may explode. Batteries
may also explode if damaged. Dispose of batteries according to
local regulations. Please recycle when possible. Do not dispose as
household waste.
