Abstract: A battery (1) having at least two serially connected cells (3?, 3?) located one above the other in a stack (2) and having flat electrodes (4, 5), the ends of the stack (2) forming the poles (9, 10) of the battery and the electrodes (4, 5) comprising connecting wires (11, 12) protruding sideways from the stack (2), at least one of the connecting wires (11, 12) of all cells (3?, 3?) being inductively coupled via a common core (13) extending approximately in the longitudinal axis of the stack, and the connecting wires (11, 12) of a first group of cells (3?) being coupled in an inductively opposite fashion to the connecting wires (11, 12) of a second group of cells (3?).
