Storage and Safety Precautions

Batteries should be stored in an open environment and placed where there is
no risk of accidental shorting or other damage. Although charged Li-Ion
batteries may be left unused for several months, their capacity may be reduced
due to back up and internal resistance. If this happens they will require
recharging prior to use. Li-Ion batteries may be stored at temperatures
between -4°F and 158°F (-20°C to 70°C).
