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).
