Glass fiber cloth introduces the maintenance-free performance of colloidal electrolyte for photovolt

Due to the use of colloidal electrolyte, the self-discharge performance of colloidal lead-acid batteries has been significantly improved. Under the same sulfuric acid purity and water quality, the storage time of colloidal lead-acid batteries can be extended by more than 2 times, and can be used for two years without charging. The capacity of 2V series after two months of standing still remains above 99.9%.
