Understanding battery usage and capacity
Sometimes I get a brain fart and just can't get out of my own way. What does battery AH ratings vs usage mean? I have (2) 6vdc gf batteries with 230ah each which means I have 230ah's to use if I...

I have 2 6-volt batteries and I also measured the amps each of my 12v appliances used. Those measurements at least gave me an idea of where my major battery draws would come from. My goal was to be able to dry camp for as long as possible without having to charge my batteries and also to keep my batteries above 50-percent SOC.
We changed out all our lights to LED and we now can run off battery power for up to a week. I would use my volt meter at the batteries every day or so to test the current voltage. The voltage reading is how I would determine the percent of SOC (I taped the standard chart to my battery compartment). The week use is spending most of our time outside, not using the furnace, basically just the frig on LPG, water pump and LED lights.
My process is not very scientific but my Trojan batteries are still going strong going into our 9th year.
