Hiow to replace wall wart on step up with battery


I've been thinking of trying to replace the wall wart on the Benz Lukaschek step up with some form of battery power supply. Has anyone done this or have any ideas about how it might be done?
Thanks for any input.

If it is a DC power supply, it would be easy. Just read how many volts the existing one supplies and the wattage and get enough batteries to equal it and wire them in series or parralel.
