Two 6 volt vs two 12 volt run time
I was just informed that two 6 volt batteries would run the residential refrigerator many times longer than two 12 volt batteries. I wonder if this is just hype?

I actually went with an Optima blue top group 31. It is 75Ah and cost about $225.
If you had gone with a LIFELINE AGM it would be 130 amp hours. OPTIMA are more expensive and far lower capacity. Just so you know.
Now.. if you are driving a 4-runner or Wave Runner or other off road vehicle. OPtima can take a licking (physically) and keep on Ticking as the watch maker used to advertise.
But for RV use.. NOT recommended for reasons in my FIRST paragraph, HIgh cost, Low capacity.
