The invention relates to a sealed lead-acid battery with multiple vertical winding cells. The sealed lead-acid battery comprises a battery case, wherein a battery cover is arranged on the top surface of the battery case; a through hole is formed in the middle of the battery cover and is internally provided with a sealing valve; the two sides of the sealing valve are respectively provided with a pole; one end of each pole is exposed while the other end of each pole extends into a battery cavity; the more than two vertical winding cells are arranged in the battery case; and positive electrodes or negative electrodes of the winding cells in the battery case are connected with one another in parallel by an upper bus bar and then electrically connected one pole. According to the invention, the mechanized mass production of winding-type sealed lead-acid batteries with capacities ranging from 0.5 Ah to 500 Ah can be achieved. The sealed lead-acid battery provided by the invention is simple in structure, reliable in performance and low in cost.
