to a charger, as overcharging may shorten
the battery’s lifetime. If left unused, a fully
charged battery will lose its charge over time.
Always 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.
Accidental short-circuiting can happen when
a metallic object touches the metal strips on
the battery, for example, if you carry a spare
battery in your pocket. Short-circuiting may
damage the battery or the connecting object.
Do not dispose of batteries in a fire as they
may explode. Dispose of batteries according
to local regulations. Recycle when possible.
Do not dispose as household waste.
Do not dismantle, cut, open, crush, bend,
puncture, or shred cells or batteries. If a
battery leaks, do not let battery liquid touch
skin or eyes. If this happens, immediately
flush the affected areas with water, or seek
medical help.
Do not modify, remanufacture, attempt to
insert foreign objects into the battery, or
immerse or expose it to water or other
liquids. Batteries may explode if damaged.
Use the battery and charger for their
intended purposes only. Improper use, or use
of unapproved batteries or incompatible
chargers may present a risk of fire,
explosion, or other hazard, and may
invalidate any approval or warranty. If you
believe the battery or charger is damaged,
take it to a service centre for inspection
before continuing to use it. Never use a
damaged battery or charger. Only use the
charger indoors.
