**■ STORAGE**

- Batteries should be stored in a dry and clean warehouse with good air exchange. They should be kept away from direct sunlight and heat sources (such as radiators) by a distance of more than 1m. Batteries should also be kept away from any toxic gases and organic solvents.

- If the ambient temperature is below 25℃, the longest storage life is 6 months. For higher temperatures, the longest storage life varies as shown 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. The charging method involves a maximum charging current of 45A, constant voltage of 2.45±0.05V/cell (25℃), with a charging time of 15~20 hours and a temperature compensation coefficient of -5mV/℃/cell.
