■STORAGE

- Batteries should be stored in a dry, clean, and well-ventilated warehouse. Avoid direct sunlight and proximity to heat sources (such as radiators, with a distance of more than 1 meter). Avoid exposure to any toxic gases and organic solvents.

- For ambient temperatures below 25℃, the longest storage life is 6 months. For higher ambient temperatures, refer to the specified storage time in the chart below:

Storage Temperature (℃)≤2526～3334～40

Storage Time (Month)631

- Batteries should be recharged within the storage life or before use. Charging method: maximum charging current of 8A, constant voltage of 2.45±0.05V/cell (25℃); Charging time: 15~20 hours; Temperature compensation coefficient: -5mV/℃/cell.
