A battery arrangement for electrical loads in a vehicle for transporting hazardous waste includes: a battery having at least a first terminal, electrically connectable to an electrical load; a first electrical resistor electrically connected in series to the battery and a second terminal, the second terminal being electrically connectable to the electrical load; and a switch component connected electrically in parallel to the first electrical resistor and connected electrically to the battery. The switch component is controlled such that a first voltage applicable to a third terminal and having a value exceeding a specifiable value closes the switch component and the first resistor is short-circuited. When the applicable first voltage falls below the specifiable value, the switch component opens and the short-circuit is broken.
