Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, reduces the capacity and lifetime of the battery. Always try to keep the battery between 59°F and 77°F (15°C and 25°C). A phone with a hot or cold battery may temporarily not work, even if the battery is fully charged. NiMH battery performance is particularly limited in temperatures below 14°F
The battery is a sealed unit with no serviceable parts. Do not attempt to open the case.
Do not dispose of a battery in a fire! Dispose of used batteries in accordance with local regulations. Recycle!
