PROBLEM TO BE SOLVED: To provide a lead-acid battery having an excellent electrical characteristic by realizing battery jar formation capable of smoothly filling the electrolyte with an accurate filling quantity of the electrolyte and realizing the battery jar formation capable of preventing intrusion of the side air during the formation of the lead-acid battery using an exterior-fitted electrolyte storage tank. SOLUTION: This battery jar forming solution filling device 1 consists of a solution storage tank 3 provided with a seal valve 7 and a tube for liquid- tightly connecting the solution storage tank and a solution filling port of the battery to each other, and the device 1 is provided with a narrow tube 5 for connecting an inner space of a cell and an inner space of the solution storage tank to each other through the inside of the described tube, and an opening provided in an upper wall of the solution storage tank is sealed with the valve. A battery jar forming method for the lead-acid battery uses this battery jar forming solution filling device to fill the whole of a cell with the predetermined quantity of the electrolyte solution filled in the solution storage tank in a formation process.
