Abstract
The present invention provides method and apparatus for the automatic recirculation of battery electrolyte from industrial and similar batteries. The invention employs a vacuum system to remove electrolyte from a cell of the battery, transfer it to a central location where it can be treated, and then return it to the battery for its continued use. The invention lends itself to many forms of electrolyte treatment, including temperature adjustment, filtering, and removal of excess gases. The invention may be readily employed on virtually all industrial batteries with minimal modification and effort, and it greatly decreases maintenance time and expense for such batteries while increasing their flexibility and uses.
