PURPOSE:To efficiently agitate electrolytes in a short time by inverting a freely flowing electrolyte for the purpose of mixture, followed by gassing, whereby a non-freely flowing electrolyte and the freely flowing electrolyte pass through a separator, for substitution and agitation. CONSTITUTION:Sulfuric acid of a low concentration is injected into a separator type lead-acid battery, which can be chemically converted. The sulfuric acid of a low concentration is discharged while sulfuric acid of a high concentration is injected. When the sulfuric acid of a high concentration is injected into a battery jar 1, an electrolyte flowing inside the battery jar 1 is laminated in a high concentration region 2 and a low concentration region. The battery is inverted. Accordingly, the electrolyte flowing inside the battery jar (i.e., a freely flowing electrolyte) can be mixed. Although the freely flowing electrolyte outside of a separator is agitated when the battery is inverted to the original state, active substance and an electrolyte intruding into a pore formed inside of the separator (i.e., a non-freely flowing electrolyte) cannot be sufficiently mixed with the freely flowing electrolyte. (Consequently, a current is supplied to the battery for the purpose of gassing so that the non-freely flowing electrolyte and the freely flowing electrolyte pass through the separator, followed by agitation. |
