Abstract: A lead-acid battery includes an electrode plate assembly, a battery case, a positive electrode strap, a negative electrode strap, a positive electrode post, a negative electrode post, a cover, and an electrolyte solution. A negative electrode bushing provided in the cover and the negative electrode post together constitute a negative electrode terminal. A maximum value of a gap between an outer circumferential surface of the negative electrode post and an inner circumferential surface of the negative electrode bushing in the negative electrode terminal is 0.5 mm or more and 2.5 mm or less. A rib is provided in a lower part of the negative electrode bushing, and a minimum value of a protrusion height of the rib is 1.5 mm or more and 4.0 mm or less. A distance between a surface of the electrolyte solution and a lowermost portion of the negative electrode bushing is 15 mm or less.

Abstract: A lid (15) of a lead-acid battery (100) includes a projecting portion (20) projecting from a base portion (19). The projecting portion (20) includes a shaft portion (27) serving as a rotation shaft of a handle (23), and an opposing wall (28) intersecting an imaginary line passing through an axial center of the shaft portion (27). A grip portion (90) of the handle (23) is located on an outer periphery of a first projecting portion (21).

Abstract: A vent plug (18) includes a head portion (35), a cylindrical portion (36), and a filter (34). The cylindrical portion (36) includes a cylinder portion (40), a screw thread portion (42), a slit (45), and a through hole (43). The filter (34) is disposed at a position where the through hole (43) is provided in a central axis (L) direction. The screw thread portion (42) intersects the slit (45) only at a first-peripheral screw thread portion.
