■STORAGE

- Batteries should be stored in dry and clean warehouse which has good air exchange system. Batteries should avoid direct sunlight. Batteries should not be near to heat (such as radiator, the distance should more than 1m). Batteries should avoid any toxic gas and organic solvent.

- When the ambient temperature is less than 25℃, the longest storage life is 6 months. If ambient temperature is higher, the longest storage life varies as specified in below chart.

Storage Temperature (℃)Storage Time (Month)

- ≤256

- 26～333

- 34～401

- Batteries should be recharged within the storage life or before using. Charging methods: maximum charging current 0.87A, constant voltage 2.45±0.05V/cell (25℃); Charging time: 15~20h; Temperature compensation coefficient: -5mV/℃/cell.
