You want to connect your standard 12 Vdc LED to a battery, unfortunately the battery you have in your possession is a 24V battery. Is it possible to step the voltage down, such as AC using step-down transformers or do you need a smaller battery of 12Vdc?

None of the above A new 13Vdc battery will be needed, to compensate for some losses No there is no way of stepping down voltage and a new 12Vdc battery will be needed Yes, there is a way of stepping down the DC voltage to the required value

The solution is simply to build yourself a DC-DC converter , comprising of a capacitor, inductor, diode, MOSFET and control system.
