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.
Use the battery only for its intended purpose. Never use
any charger or battery that is damaged. Keep your battery
out of the reach of small children.
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.
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.
