**■STORAGE**

- Batteries should be stored in a dry and clean warehouse with a good air exchange system. They should avoid direct sunlight and proximity to heat sources such as radiators (maintain a distance of more than 1m). Additionally, batteries should be kept 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 chart below:

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

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

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

- Batteries should be recharged within their storage life or before using. Charging methods: maximum charging current 27A, constant voltage 2.45±0.05V/cell (25℃); Charging time: 15~20h; Temperature compensation coefficient: -5mV/℃/cell.
