**■STORAGE**

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

- Avoid direct sunlight and keep away from heat sources (such as radiators, with a distance of more than 1m).

- Keep away from any toxic gas and organic solvent.

- If the ambient temperature is below 25℃, the longest storage life is 6 months. For higher ambient temperatures, refer to the specified storage time 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: Maximum charging current is 67.5A, constant voltage is 2.45±0.05V/cell (25℃); Charging time: 15~20 hours; Temperature compensation coefficient: -5mV/℃/cell.
