CA: Rated Capacity at 25℃
The operating environment temperature above 40℃ should be avoided ,After long term storage, The battery actual capacity would
be less than the rated capacity. Full capacity will be obtained through several charge/discharge cycles.
To get the longest life, POWERMAN battery should be fully charged before storage.
