Disclosed herein is an automobile lead-acid battery, which comprises a case internally divided into a plurality of separate cells by a plurality of partitions, a plurality of positive plates and a plurality of negative plates alternately interleaved with one another within each of the plurality of cells. A separator is disposed between the positive and negative plates to separate them. An electrolyte is filled in the remaining space of each cell. The positive plate includes an upper frame formed at one side with a lug protruding upwardly, a lower frame positioned in parallel with the upper frame, side frames coupled to both ends of the upper and lower frames to thereby form a square framework with four rounded corners to prevent damage to the separator. A plurality of inner grids is disposed within the square framework and taking a radial shape.
