Are all amp hrs equal?
Say you have 230 amp hrs in 2 6vGC batteries and you discharge at a low amp rate say 1 amp so if you discharge to 50 percent SOC you should have used 115 amps in 115 hrs. If you then discharge at a h...

Thanks for all the explanations. I have a friend with a 2012 Pheaton with 6 6v GC batteries in it. He has a residential refer and a lot of electronic devices inside. On the other hand I have a 1996 GBM with 2 6 v GC batteries but very low amp usage water pump and a few lights. When dry camping I go 7 days before drawing down to 50 percent SOC on the other hand he has to run his genset 2 hrs a day to stay above 50 percent. I never could figure out why before I thought his batteries were bad.
The explanation there has much more to do with simple ratios of battery capacity to energy usage. His battery capacity is about three times yours, but his electric usage rather much more than three times your usage. The residential fridge uses somewhere roughly around ten times the electrical energy of your absorption fridge's control board (but, of course, no propane).
