Abstract
Abstract Electric accumulator cell arranged in a cell box, the positive and negative essentially plane electrode plates being joined together into separate groups of electrodes by means of plate straps and being further lowered into a liquid electrolyte and provided with current discharging means for withdrawal of current to a consumer, said withdrawal taking place through at least two current discharging means connected to the corresponding number of plate straps on the electrode plates.
