I've been using the same car battery for4 years. Nothing but led lights, lot's of them. I use a 100 watt solar panel on good days to keep a charge when shore power is not available. I can usually come across a slightly used car batteries pretty easily. I have a few cars in the family and seems one of them needs a battery now and then, I just recycle them through the camper before I scrap them. No fridge, TV, heater, just lights. Thought about getting a generator but can't justify the hassle. If I ever get a spare 300 bucks I'll buy a real battery.
