Sealed lead acid battery
A sealed lead acid battery is described which consists of: (a) a container having a rectangular base, four side walls approximately perpendicular to the base and vertical partitions dividing the container into a series of separate chambers, the container being formed from a polypropylene resin containing 5 to 20% inert filler and having a wall thickness of 2 to 4 millimeters; (b) cell elements inserted into the chambers, each cell element consisting of at least one rectangular negative plate and at least one rectangular positive plate, arranged serially, each plate being separated from the next by a rectangular, microfibrous, glass separator, having a length and a width greater than that of the plates, the cell elements being pressed into the chamber so as to have an enforceable positive pressure on the negative and positive plates of between 35 and 60 kg/cm/sup 2/; (c) straps, connecting the positive and negative plates of each cell respectively; (d) a cover body sealed to the container, the cover body having a plurality of filler ports, a negative terminal, a positive terminal, and a gas collection system consisting of a common manifold, venting passages connecting the manifold to openings in the top of each of the chambers, a common vent, the vent being formed in a recess in the surface of the cover and comprising a cylindrical, small diameter tube projecting vertically from the common manifold, a plurality of notches formed in the upper portion of the tube, and an elastic cap vertically and horizontally covering the upper tube portion; (e) a gas permeable filter, fixedly arranged in the vent, superimposed upon and restraining the elastic cap of the common vent; and (f) a loosely fitting cover detachably mounted upon the cover body over the filter, wherein the elastic cap positively seals the upper tube portion.
