Portable direct-connection type container formation valve-regulated sealed lead-acid storage battery

A portable direct connection type container formation valve control type sealed lead-acid storage battery comprises an outer shell composed of a storage battery groove and a storage battery cover, sixunit cells are arranged in the outer shell, pole groups are assembled in the unit cells respectively, the tops of plate lugs of the pole groups are connected with busbars, and the adjacent pole groups are directly connected through the busbars. Busbar assembling grooves are formed in the upper portions of the middle partitions of the adjacent unit cells in the storage battery groove, sealing rings are arranged at the positions, located at the connecting positions of the two adjacent pole groups, of the busbars, and the connecting positions of the adjacent pole groups of the busbars and the sealing rings are pressed into the busbar assembling grooves. According to the utility model, a middle pole and a pole connecting piece are canceled, so that the internal resistance of the battery is greatly reduced, and the ad
