STORAGE: 5.1 It is strongly recommended to stored Ni-MH batteries and cells in the temperature range from -20℃ to 35℃,and in low humidity and no corrosive gas environment, to maintain a reasonably high capacity recovery level. 5.2 Avoid storage higher (e.g. 35℃), lower temperature than -20℃, or higher humidity which would result in deterioration or damage to the cells and batteries such as follows: . Permanent capacity loss. . Electrolyte leakage resulted from the expansion or shrinkage of organic material inside the cells. . Rust of metal parts. 5.3 Up to three full cycles of charge/discharge after long-term storage may need to obtain highest capacity. 6.
