The length of time that batteries can be stored in a warehouse depends on several factors, including the type of battery, the storage conditions, and the charge state of the battery. In general, it is recommended to use batteries within 6 to 12 months of purchase. If stored properly, most batteries can be stored for up to 2 years without a significant loss of performance.
To maximize the lifespan of stored batteries, it is important to store them in a cool, dry, and well-ventilated area at a moderate temperature, away from moisture and other sources of humidity. Batteries should also be stored in their original packaging or in a container specifically designed for battery storage, and in a low-charge state to help prevent short circuits and minimize the risk of leakage or damage. Regular checks of the battery charge level should also be performed during storage.
