PURPOSE:To manufacture a lead-acid battery having a high-rate discharge characteristic and a long life by increasing the formation property for battery jar formation. CONSTITUTION:An active material paste kneaded with the lead oxide powder containing minium, sulfuric acid, and water is filled in a current collector to form an undried positive electrode plate, and the undried positive electrode plate is aged and dried to manufacture an unformed positive electrode plate. The unformed positive electrode plate and an unformed negative electrode plate are combined to form an electrode plate group, and the electrode plate group is arranged in a battery jar and formed via battery jar formation. The quantity of minium and the processing condition of the aging/drying processes are determined so that tetrabasic lead sulfate and lead dioxide are mixedly contained in the unformed positive electrode plate. |
