An electric storage battery having a battery gas venting system including: an electrolyte-trapping chamber; an exhaust port for venting battery gases to the ambient; a porous flame arresting filter between the electrolyte-trapping chamber and the port; a combustion chamber adjacent the exhaust port for the controlled combustion of the battery gases; a buffer chamber intermediate the porous filter and the combustion chamber; a partition separating the combustion and buffer chambers; and a relatively small aperture communicating the combustion and buffer chambers one with the other. The aperture between the buffer and combustion chambers preferably has an effective cross-sectional area which is no more than about one-half the cross-sectional area of the exhaust port.

In a venting system for an electric storage battery including an exhaust port for venting battery gases to the ambient and means for quashing any flame invading said system through said port, said means comprising: a porous flame-arresting filter intermediate a cell of said battery and said port for permitting egress of said gases while preventing ingress of said flame; a combustion chamber adjacent said port for the controlled combustion of said gases therein; a buffer chamber intermediate said combustion chamber and said filter to mitigate the impact of said controlled combustion on said filter; a partition separating said combustion and buffer chambers one from the other; and an aperture through said partition for communicating said combustion and buffer chambers, said aperture having an effective cross-sectional area which is sufficiently less than the cross-sectional area of said port that the forces generated by said controlled combustion are relieved primarily through said port and serve to prevent establishment of a sustained flame at said port incident to the ignition of said gases thereat.
