One hour is not long enough for the fridge to get cold. You need to let it chill over night, or at least all day.

The 675 amps is cold cranking amps(CCA). Meaning it can put that much out in short bursts, as in starting. 6 volt golf cart/RV batteries are rated in ampere hour. How many sustained amps they can put out over a certain period of time. See post #4. Trojan and other RV 6 volt batteries are usually rated around 225 amps, but that isn't CCA. Go here and look at the ratings for a T-105.

Then he posted he had wired them as I interpreted this as neg on bat 1 to neg on bat 2, Pos Bat 1 to Pos bat 2, or like the drawing I posted. Was I wrong? If so I am deeply sorry for any confusion.
I read it the same way.. no worries..

If you use (2) 12 volt batteries wired in (parallel) you will have 12 volts with the amperage of each battery available for a short time. Unless the batteries are deep cycle batteries they will not run the coach on purely battery for as long as 2 large 6 volt deep cycle batteries wired in (series) will. Large coaches have (4) 6 volt batteries wired to provide 12 volts to the system. They are high capacity deep cycle, deep discharge batteries. Mine will run for days providing inverter power for TV, vents, lighting and such. Never saw a motorhome wired for 24 volts but I never saw a million dollars either. Careful when you decide on how you will proceed with your batteries. It only takes a second to undo many $$$$$$ of things in you motorhome.

Thanks to everyone!

The Bounder has two new 6 volt batteries as it should be. All systems are working properly. Taking first short trip to San Diego next week. Thanks again.

I have a 2004 Bounder 35R and the two batteries are 6volts each hooked in series to give me 12volts. If you are hooking two 12volt batteries make sure they are parallel.
