Lead-Acid (LA) and Nickel Cadmium (NiCd) batteries vent hydrogen and oxygen when they are being charged. In the case of Valve-Regulated designs, the hydrogen is recombined with the oxygen within the battery back into water unless the gassing volume/pressure exceeds the opening setting of the pressure relief valve. Hence the name Valve-Regulated. Oxygen gas is …
