A lead battery employing a collective exhaust system and exhibiting excellent gas exhaust function and electrolyte leakage preventive function in which the electrolyte does not leak even when the battery turns sideways. In the lead battery equipped with a collective exhaustion mechanism, a partition wall is arranged to surround an opening consisting of an electrolyte circulation opening (33) and a gas exhaust opening (34), a cell communicating subchamber (35) sectioned from exhaust chambers (37, 37', 37") by the partition wall is provided, and the cell communicating chamber (35) is communicated with the exhaust chambers (37, 37', 37") through a cut (36) provided on the partition wall, and the cell communicating subchamber (35) is isolated from the exhaust chambers (37, 37', 37") by the partition wall excepting the cut (36).
