Forrest if you have the Amana w. ice maker it will average about 90 watts depending how many times you open the door (bulb) so with your 3 batteries fully charged to the float level u should see about 33 hrs time.... but you will also use lights and water pump..No? TV? what else?? Microwave uses about 1100+ watts....It will all mean less time.. I was reading that the refer takes about 1000w on startup (surge) so door open time has effect...
