**■STORAGE**

- Batteries should be stored in a dry and clean warehouse with good air exchange system.

- Avoid direct sunlight and proximity to heat sources (such as radiators, with a distance of more 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 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 use. Charging methods include a maximum charging current of 15A, constant voltage of 2.45±0.05V/cell (25℃), charging time of 15~20 hours. The temperature compensation coefficient is -5mV/℃/cell.
