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?

Two 6V batteries in series.......12V with SAME amp hour
Two 12V batteries in parallel----12V with double amp hour
So depends on WHICH 6V/12V and their amp hour ratings
Such a simple and clear response in a sea of fog. :)
If your 6v batteries are 210Ah, then two will give you 12v @ 210Ah total.
If your 12v batteries are 55Ah, then two will give you 12v @ 110Ah total.
Many people (and manufacturers\dealers) will install cheap basic 12v batteries. Even with 2, you are not getting a lot of amp hours out of them. So upgrading to 2 6v batteries will often give you more bang for your buck.
However, if your 12v batteries are of better quality, that significant benefit can become minimal.
