Battery refill system of a lead acid battery with components for forming a gelified electrolyte

Device for filling pot (20) of a lead battery comprises: reservoirs (1, 2) enclosing sulfuric acid and mixture of water and gelling agent, respectively; containers (4, 5) each connected to one of the reservoirs and incorporating a piston (10, 11) for expelling constituents into conduits (17, 18); mixer (16) into which conduits emerge; and conduit (19) connecting mixer to pot through cover (21). A device for filling the pot (20) of a lead battery comprises: (a) at least two reservoirs (1, 2) enclosing sulfuric acid and a mixture of water and a gelling agent, such as silica particles, respectively; (b) at least two containers (4, 5) each connected to one of the reservoirs and incorporating a piston (10, 11) for expelling the constituents into conduits (17, 18); (c) a mixer (16) into which the conduits emerge; (d) a conduit (19) connecting the mixer to the battery pot through the battery cover (21). The pistons are preferably connected to a single control device (15) and includes a system for establishing a reduced pressure in the battery.
