PURPOSE:To improve the life characteristic of a battery by pouring dilute sulfuric acid into a battery jar before battery jar formation, by draining electrolyte after the formation is finished, and by re-pouring the electrolyte of high concentration sulfuric acid, to which alkaline metal sulfate is added, so as to carry out re-charging thereafter. CONSTITUTION:Before battery jar formation, dilute sulfuric acid of specific gravity of not less than 1.050 and not more than 1.180 is poured into a battery jar, and an electrolyte is drained from the battery jar after the battery jar formation. The electrolyte of high concentration sulfuric acid to which alkaline metal sulfate is added is re-poured, and re-charging is carried out thereafter. The problem of dissolution and falling of a plate active material at the initial stage of battery jar formation is thus solved, and the life characteristic of the battery is improved while the battery jar formation can be carried out effectively. |
