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.
Leaving the battery in hot or cold places, such as in a closed car
in summer or winter conditions, will reduce the capacity and
lifetime of the battery. Always try to keep the battery between
15°C and 25°C (59°F and 77°F). A device with a hot or cold battery
may not work temporarily, even when the battery is fully charged.
Battery performance is particularly limited in temperatures well
below freezing.
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 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.
