Abstract

The battery cover includes a valve controlling the entry of electrolyte, and an outlet for the gas produced by electro-chemical action. The top-up valve for water of electrolyte includes a corrosion resistant float (11) partially immersed in the electrolyte, attached to a head (10). The head moves axially in a valve seating (8) to allow entry of electrolyte up to a preset level. The gas outlet comprises a threaded stopper (20) fitting into the top of the cover, with a ceramic disc (24) underneath the outer apertured cover (26). The disc allows the passage of gas without allowing acid to leak out.
