65 Warnings and precautions
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.

Batteries may also explode if damaged. Dispose of batteries
according to local regulations. Please recycle when possible.
Do not dispose as household waste.

explosion.
