Abstract
An accumulator with an accumulator housing, having at least one cell changer, with several electrodes and liquid electrolyte in each cell chamber with at least one wall element in the cell chambers to divide the cell chambers into at least two intercommunicating volume chambers. In the lower region of the volume chambers is a communicating connection for the liquid electrolyte between the volume chambers and a pressure equalization connection between the volume chambers is arranged in the upper region of the volume chambers to assure an equivalent air pressure in the intercommunicating volume chambers. The wall elements extend at least far upwards such that on movement of the accumulator firstly electrolyte in at least one volume chamber flows through the intercommunicating connection in the lower region and secondly electrolyte again flows through the intercommunicating connection in the lower region out of said at least one volume region without an overflow of liquid electrolyte from one volume chamber to the adjacent volume chamber over the upper edge of the wall elements.
