■STORAGE

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

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