In an electric storage battery having a venting system for relieving gases from the innards of the battery including an electrolyte trapping chamber defined in part by a floor sloping toward an electrolyte drainage aperture at the low point of the floor and proximate the electrolyte level within the battery, the improvement comprising: a rim defining said aperture and a tongue-like drip tab depending at an acute angle from the underside of said rim so as to extend beneath said aperture and promote the running off of electrolyte from said floor back to said innards which electrolyte, but for the tab, would otherwise accumulate on said floor and plug said aperture.
