A dual-voltage battery for a vehicle includes a plurality of battery cells, wherein in each case a group of battery cells is connected to a battery cell block, and a battery electronics system with a plurality of power switching elements for connection in series or in parallel of in each case individual battery cell blocks. In a first connection arrangement of the battery cell blocks, a first voltage is provided and in a second connection arrangement, a second voltage is provided. At least a first battery cell block is provided as part of a first voltage supply unit, at least a second battery cell block is provided as part of a second voltage supply unit, at least two third battery cell blocks are provided as part of a third voltage supply unit, and at least two fourth battery cell blocks are provided as part of a fourth voltage supply unit.
