-20°C to 55°C (-4°F to 131°F)
Discharge Temperature
a
-20°C to 60°C (-4°F to 140°F)

c
-20°C to 45°C (-4°F to 113°F)
Storage Temperature (6 months)
c
-10°C to 30°C (14°F to 86°F)
a
This is the specified temperature of the cells and not ambient. Ambient temperature and cell temperature may not
be the same.
b
The Battery Management System will not allow charging of the cells below 0°C. When charge begins below 0°C, the
energy is diverted to the internal heating until the cells reach 2°C, at which time cells will begin to be charged.
c
Storage outside of specified temperatures will result in permanent capacity loss and invalidate the warranty.
