ABSTRACT:
An auxiliary electrode of platinum or palladium is immersed in the electrolyte of a lead-acid battery and connected to the negative plate of the battery so that, when the battery is employed in float service, hydrogen evolves on the auxiliary electrode whereby the parasitic current equivalent to the hydrogen evolution increases the float current to the positive plate of the battery.
