**■STORAGE**

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

- Avoid direct sunlight and proximity to heat sources (such as radiators, maintaining a distance of more than 1m).

- Keep away from any toxic gases and organic solvents.

- When the ambient temperature is below 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 (℃) | Storage Time (Months) |

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

| ≤25                      | 6                     |

| 26～33                   | 3                     |

| 34～40                   | 1                     |

- Batteries should be recharged within the storage life or before use.

- Charging methods: maximum charging current of 36A, constant voltage of 2.45±0.05V/cell (25℃); charging time: 15~20 hours; temperature compensation coefficient: -5mV/℃/cell.
