**■Storage**

- Batteries should be stored in a dry and clean warehouse with good air ventilation. They should be kept away from direct sunlight and heat sources (such as radiators, with a distance of more than 1 meter). Avoid contact with any toxic gases or organic solvents.

- If the ambient temperature is below 25℃, the longest storage life is 6 months. For higher ambient temperatures, refer to 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 use. Charging methods involve a maximum charging current of 7.2A, constant voltage of 2.45±0.05V/cell (25℃), with a charging time of 15~20 hours. Temperature compensation coefficient is -5mV/℃/cell.
