Abstract

An electrolyte reservoir in fluid communication with the cell of a storage battery is intermittently pressurized with a pulse of compressed gas to cause a flow of electrolyte from the reservoir to the upper region of less dense electrolyte in the cell. Upon termination of the pressure pulse, more dense electrolyte is forced into the reservoir from the lower region of the cell by the differential pressure head between the cell and reservoir electrolyte levels. The compressed gas pulse is controlled to prevent the entry of gas from the reservoir into the cell.
