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 tempertures 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 tempertures 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.
