BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead acid battery, and more particularly, to an industrial lead acid battery which is manufactured by melting a lug portion of an electrode plate together with a welding rod.

2V industrial lead-acid batteries are mainly used for communication base stations for UPS, and they are widely used from 150Ah to 3,000Ah, and they are manufactured by connecting one cell or a plurality of cells in parallel.
