A normally sealed lead-acid cell of the oxygen recombination type comprising a cell housing, in which is disposed at least one porous pasted positive electrode plate made from a thixotropic paste, at least one porous pasted negative electrode plate made from a thixotropic paste, a multilayer absorbent porous separator interleaved between the opposite polarity plates and an electrolyte in a starved amount absorbed in the pores of the plates and separator, said separator including first and second layers, each comprised of a mat of microfine glass fibers, of which the average fiber diameter on a weight basis is less than about b 5 microns, one face of the first layer being integrated into the adjoining face of the positive plate by having a substantial quantity of its microfine glass fibers embedded in the positive paste material, and the other face of the first layer being free from contact with an electrode plate, and one face of the second layer being integrated into the adjoining face of the negative plate by having a substantial quantity of its microfine glass fibers embedded in the negative paste material, and the other face of the second layer being free from contact with an electrode plate.
