1. In combination, a sealed lead-acid gas recombining battery capable of discharge and charge in any attitude without electrolyte loss, comprising:

  • a plurality of electrochemical cells housed in a sealed monobloc container, the cells individually comprising porous positive and porous negative plates sandwiching a porous compressible separator under firm mutual stacking pressure, and an acid electrolyte in liquid form and of limited amount tightly absorbed within the plates and separator;

    said separator having a relatively greater electrolyte absorptive power than the adjoining plates with the bulk of the electrolyte of each cell being retained in the pores of the separator, and a substantial portion of the pore volume of the plates remaining voided thereby facilitating gas transport during the gas recombination reaction upon charging; and

    partition members segregating the cells from direct physical contact yet constructed to define a gas space common to all the cells of the battery.
