Storing spare battery packs
Length of time
The Lithium-ion battery pack cannot be stored
indefinitely. It will self discharge and eventually
become inoperable. To prevent this, charge the
battery pack at least every six months.
Environment
Store your lithium-ion batteries in a cool, dry, well-
ventilated, and weatherproof location where the
temperature is –4 to 104° (–20 to 40 C°).
