Rez fridge question
A blanket question, but on average those with residential fridges, how long will can it run on a single 12V deep cell battery? I know there are variables here, size of battery, parasitic draws etc...

Hours; maybe 12ish hours on average, if there is such a thing as average.
This is a question that can be answered pretty well, at least well enough for back-of-the-envelope calculations, by comparing the usable energy storage of the battery with the energy consumption of a residential fridge. According to the Energy Star labels I've seen, a typical not huge fridge use around 1 kWh or a bit more per day on average (under their test conditions). A single marine/RV battery has maybe 50 Ah of usable charge, which multiplied by 12V yields 600 Wh or 0.6 kWh of energy.
