ABSTRACT:
An improved battery formation apparatus wherein a specially designed overflow/drain plug is provided for directing the flow of fluid out of a water tub used to control the temperature of batteries during the formation thereof. The plug is a combination of a hollow plug member and a collar member fitted around this plug member. The plug member is designed to fit inside the drain opening and extend upward therefrom to control the liquid level in the container, and furthermore, the plug is designed to fit around the bottom of the drain opening to facilitate draining of the fluid from the opening. The plug member has an elongated slot therethrough, and the collar means is slidably fitted around the plug member to adjustably determine the height along the plug member which the fluid must reach before it is drained through the elongated slot.
