Product and safety information 71
Proper charging. 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.
Avoid extreme temperatures. 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. 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.
Disposal. Do not dispose of batteries in a fire as they may explode. Dispose of batteries
according to local regulations. Please recycle when possible. Do not dispose as
household waste.
Leak. Do not dismantle, cut, open, crush, bend, puncture, or shred cells or batteries.
In the event of a battery leak, prevent battery liquid contact with skin or eyes. If this
happens, flush the affected areas immediately with water, or seek medical help.
Damage. 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.
Correct use. Use the battery only for its intended purpose. Improper battery use may
result in a fire, explosion, or other hazard. If the device or battery is dropped,
especially on a hard surface, and you believe the battery has been damaged, take it
