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 don't think I have ever seen AGM big 12 volt batteries at a Meijer store either but I wouldn't want one anyway as their Ah capacity is so much lower than a lead acid of the same size and everywhere I do see them they are about double the price of a lead acid same size battery so why would I even want one? I'd need to have about 8 of them to have the same amp hours of my 5 lead acid batteries and at a very high cost and they will still need replacing every 8-10 years. Why would I replace a very good working lots of mice catching mousetrap with 2 that only catch half as mant mice each at a lot higher purchase price? Dumb to do in my book!
Adding water to a lead acid battery is certainly no big deal as at most I only do it once a year and they have never been low enough to even be near the top of the plates in any cell. The batteries are in a large Tupperware plastic covered box in my 5th wheel front outside compartment under bed over hang. has a couple small holes drilled thru the cover for air to enter and there's a glued/screwed on "L" shaped 3/4" dia plastic water pipe elbow at the bottom on one end going thru the bottom of the compartment to the outside so the gasses will constantly escape outside and not into the compartment. The gasses from the batteries is heavier than air so they flow out naturally as they are replaced by the fresh air coming in thru the several small breathe holes in the cover.
I have had well over 50 lead acid batteries in our 56+ years of marriage and only a couple ever shorted out or failed so far. Hey, one of those was a 6 volt golf cart battery and made its mate for getting 12 volts USELESS! Self-explanatory!
Like I said, I don't give 2 hoots what other people want, do, or use. I simply know from over 50 years experience of RV'ing and boating batteries what works best for me and, if it's not broke, why try fixing it as it's working so great already and very cost effective? Then when I do put new batteries in the RV's, the old batteries have an after RV life using until I decide to use some for avoiding the core charge for getting new batteries.
