Abstract
The present invention relates to a lead acid storage battery and provides a lead acid storage battery having a high durability against complicated vibrations such as perpendicular and horizontal vibrations and the combination of these vibrations applied by vehicles or machines on which the battery is installed and having a long shelf life. A polyolefin resin having good fluidity is heat molten and poured into two portions above and near the left and right ends of the plate group comprising positive and negative plates having lugs at nearly the center portion so that the resin reaches at least one of the inner wall or inner partition wall, thereby to form a beam-shaped plate fixing member.
