Unplug the charger from the electrical plug and the device

its charge over time.
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 the battery. Accidental short-
