PURPOSE:To decrease rapid deterioration of the capacity of a battery caused by low- rate discharge, by holding, within a specific range, the concentration of sulfuric acid remaining in the electrolyte at the last stage of the initial low-current discharge. CONSTITUTION:At the last stage of the initial low-current discharge of a lead acid battery where the hour rate of the discharge is below 5 (0.2 C), especially 0.2- 0.05 C, the concentration of sulfuric acid remaining in the electrolyte is suppressed below 20wt%, preferably restricted to 15-5wt%. The simplest method of regulating the sulfuric acid concentration at the last stage of the discharge is, for example, to carry out discharge in a sufficient acid concentration, before replacing the liquid with sulfuric acid of a given concentration below 20wt%. |
