**■Storage**

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

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

| Storage Temperature (℃) | ≤25   | 26～33 | 34～40 |

|--------------------------|--------|--------|--------|

| Storage Time (Month)     | 6      | 3      | 1      |

- Batteries should be recharged within the storage life or before using. Charging methods include a maximum charging current of 7.5A, constant voltage of 2.45±0.05V/cell (25℃), charging time of 15~20 hours. The temperature compensation coefficient is -5mV/℃/cell.
