Abstract: A leak retardant automotive battery includes a housing containing a plurality of cells that each have a filling plug and a battery cover closing the housing above the cells. The battery cover includes a central blockage that divides the housing into two compartments that each contain a set of cells. The cells in each compartment are connected by vent holes in the battery cover that are respectively connected to associated vent cap assemblies so as to separately vent each compartment through its associated vent cap assembly.

Abstract: Leak retardant automotive battery comprising a housing for a plurality of cells housed therein and each having a filling plug and a battery cover provided onto the housing to overlie the cells and divided into two compartments by means of a central blockage, each compartment overlying a set of cells, each of vent lines connecting vent holes in the battery cover overlying each set of the cells so that the cells in each set are in communication with each other and being connected at its one end to the central blockage so as to isolate the two compartments; a vent cap assembly being provided at the other end of each of the vent lines for escape of vented gases.
