Abstract: A lead-acid battery is provided with a lid. A communication chamber is formed inside the lid. In the communication chamber, a first distance between an inner wall and a vent hole in a sidewall is shorter than a second distance between the inner wall and an exhaust hole, and a tip of the inner wall is formed below the vent hole in a direction opposite to the first direction.

Abstract: A lead-acid battery (100) is provided with a lid (14). An external flow passage (530) communicating with a communication chamber (520) through a vent hole (321) and communicating with a discharge port (405) of a lid (14) is formed inside the lid (14). A compartment fence (452, 454) continuously extending over the entire width of the external flow passage (530) is formed in the external flow passage (530). A residual volume is larger than the volume of the communication chamber (520), the residual volume being obtained by subtracting, from the total volume of a plurality of external spaces (460, 462, 464) divided by the compartment fence (452, 454), the volume of the discharge-side external space (464) closest to the discharge port among the plurality of external spaces.
