This invention is a method of making negative battery plates in a continuous process, in which a skeletal grid is cast continuously to have the structure of a number of plate grids side by side and longitudinally integrally connected together in the casting. After casting the skeletal grid is pasted, tissues are applied on either side, and then the grid is cut by slitting and transversely to separate the composite grid into separate pasted battery plates.

Method of making battery plates

A method of manufacturing a recombinant lead acid battery includes placing two or more cell packs in a battery container and then loading the container into a frame mounted on a rotary capstan. The container is transferred to a moulding station and the plate straps and intercell connectors are moulded around the plate lugs. The container is then transferred to a coating station and the intercell connectors are dipped while still hot into a fluidized bed of epoxy resin particles. The particles adhere to the intercell connectors and are cured by their heat thereby forming an impervious layer around them. This layer acts as an electrolyte creepage barrier and prevents the surface of the intercell connectors acting as an electrolyte path for intercell ionic leakage.
