**■Storage**

- Batteries should be stored in a well-ventilated, dry, and clean warehouse;

- Avoid direct sunlight and proximity to heat sources (such as radiators, with a distance greater than 1m);

- Avoid contact with any toxic gases and organic solvents;

- When the ambient temperature is below 25℃, the longest storage life of the battery is 6 months. If the ambient temperature is higher, the longest storage life of the battery will vary 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 use. Charging methods include a maximum charging current of 12A, constant voltage of 2.45±0.05V/cell (at 25℃), charging time of 15~20 hours. The temperature compensation coefficient is -5mV/℃/cell.
