**■STORAGE**

- Batteries should be stored in a dry, clean warehouse with good air ventilation.

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

- Keep away from any toxic gases and organic solvents.

- If the ambient temperature is below 25°C, the longest storage life is 6 months. For higher temperatures, refer to the specified durations in the table below:

  | **Storage Temperature (°C)** | ≤25   | 26～33 | 34～40 |

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

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

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

- Charging method: Maximum charging current of 58.75A, constant voltage of 2.45±0.05V/cell (25°C); charging time: 15~20 hours; temperature compensation coefficient: -5mV/°C/cell.
