■ STORAGE

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

- If the ambient temperature is less than 25℃, the longest storage life is 6 months. However, if the ambient temperature is higher, the longest storage life varies as specified in the chart below:

  Storage Temperature (℃)Storage Time (Month)

  - ≤256

  - 26～333

  - 34～401

- Batteries should be recharged within the storage life or before use. The charging method involves a maximum charging current of 2.7A, constant voltage of 2.45±0.05V/cell (25℃), a charging time of 15~20 hours, and a temperature compensation coefficient of -5mV/℃/cell.
