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.
Do not dismantle, cut, open, crush, bend, deform, puncture, or shred
cells or batteries. In the event of a battery leak, do not allow the
liquid to come in contact with the skin or eyes. In the event of such a
leak, flush your skin or eyes immediately with water, or seek medical
help.
