Abstract
A lead-acid battery includes cell rooms in which cells are stored and a partition wall separating the cell rooms. The cell rooms include an electrode plate assembly having electrode plates facing each other with a separator sandwiched between the electrode plates, and positive and negative straps extending in a laminated direction of the electrode plates in a bar shape. The positive and negative straps are connected in parallel with lug portions of the electrode plates. An intercell electrically connecting member having a H-shaped cross-section and formed of a lead-based material is held by the partition wall to interconnect cells in adjacent cell rooms. The intercell electrically connecting member has a first butting end surface in a flat plane shape butt welded to the positive strap, and a second butting end surface in a flat plane shape butt welded to the negative strap. Butting connection of the intercell electrically connecting member and each of the positive and negative straps improves their connecting strength.
