The invention relates to a battery with battery cells and a method for monitoring and controlling the battery cells of the battery. The battery has a plurality of battery cell stacks which are connected in series. A battery cell stack may have an individual battery cell or may be constructed from battery cells which are connected in parallel. Sensors monitor the charge state of individual battery cells, individual battery cell stacks, individual pairs of battery cells and/or individual pairs of battery cell stacks. A charge compensation device has a target value table of the permissible charge state of individual battery cells. The charge compensation device varies the charge compensation depending on the charge state and, when the target value for the charge state of individual battery cells is reached, the charge compensation of the battery cells is interrupted.
