which way is best 2 6V or 2 12V batteries

What he said doesn't make sense. Double the capacity is double the gain. Where's the 25% come from?

This is such a no brainer that it makes my head hurt. Like Mex said, why do golf carts that take a pure beating every single day use 6 volt batteries???

Just make sure they are Trojans!

Gee. Mexico... Are you agreeing with me (What I said, is "Best" is subject to opinion but the Golf Car batteries give the best bang for the buck.. The best value, the lowest cost, however you wish to phrase it.

And you gave the reason rather well.. I'll give you another.

(you hinted at it) Golf courses and such buy those suckers by the pallet load.. They are, most likely, the most common 12 volt lead acid battery ever.. The lines that make them run a long long time without re-tooling. and that lowers the per unit cost.

12 volt styles.. Well you have about a hundred different "Automotive" type 12 volt batteries (more or less, I just pulled that number out of air) you may well run a line just one day before re-tooling or a different battery size.. Adds big time to the cost.

What a topic, almost as good as Chevy v. Ford or Dually v. SWR.
We have lived in the 12 volt world for a long time. We lived aboard a sailing yacht for 23 years. We carried 3- 4D Diesel Starting Batteries plus 4 additional smaller batteries. Over the years we had many combinations of 6 & 12 volt batteries. We charged with alternator, generator, propeller shaft alternator, wind and solar.

What we learned was, after three years of use at sea, replace lead acid batteries, regardless of voltage. We did not have AGM tech then but did try gel cell, which were not successful. We have found that AGM 12 volt are very trouble free and easy to manage, weight, size and power wise. Deka by Penn Manufacturing are the best value I've found for AGM batteries.

I've had both.
I now have 4 - 6 volt batteries rather than 2 - 12 volt batteries.
The 4 6 volt batteries out perform the 2 12 volt batteries by about 25%. I'll never go back to 12 volt batteries.
Ever wonder why golf carts use 6 or 8 volt batteries and not 12 volt????

Now, read this quote,.....and then you tell me that 6'ers are better than 12'ers. Hes talkin double the capacity, and only 25% actual gain ??? That is really pathetic for the 6'ers !!
And he'll never go back to 12's ?? I would, in a heartbeat !

Eorget what all them other yahoos say, there ain't a dimes worth of difference tween 6 & 12.

Actually there is a difference but may be irrelevant when talking about RVing. I like MEX's answer the best. Depends on how your camping style is.

Eorget what all them other yahoos say, there ain't a dimes worth of difference tween 6 & 12. Either way ya go, ya have around 220 am hrs.
After 50 years, I now run 12'ers.

Need to upgrade battery.
Which way is best for most lasting power?
Have room for either situation.

2 6V or 2 12V looking at group 30 110 AH
Thanks

Forget the technical mumbo jumbo....

I had 2 12volts.....furnace would run them down before morning....

I now have 2 6volts......problem solved....

Nuff said
Happy Travels

Myself, I relied on the pallets of batteries that we junked - usually 12 to 20 per month. Businesses that rely utterly on the cost per kWh over a period of years (for vehicles that are powered) rely on GC-220 batteries. They decide this on a hard core dollars and cents basis. If they could find batteries that last three times as long at twice the price they would buy them. Unless of course you figure an RV owner knows more about batteries than a business owner who may purchase two to three hundred batteries a year, does the cost analysis on a computer (including maintenance and electrical recharge costs), and has a penny-pinching comptroller looking over his shoulder.
If you want to argue this point, go to any large golf course, and argue with the Golf Pro and the accountant. When they're done with you, the owner will take over and I guarantee you'll crawl out of there little more than raw hamburger.

Various battery designs have pluses and minuses. It's up to the user and no one else on earth to be interested enough to find out which suits his purposes best. Joe McGee down the street may have an RV with a totally different lifestyle than yours. A different rig, a different world. If you let him twist your arm and buy what he suggests, chances are, you will end up on the short end of the stick.

Golf car batteries face an insanely fierce and competitive market. This is because of computer monitoring and analysis right down to the very last shiny copper plated zinc penny. People who lay out tens of thousands of dollars a year on batteries tend to be ruthless how they save money. They cannot cheat. They do not base their decisions on opinions - merely cold hard facts in the form of numbers. Numbers with dead presidents on the face.

Let me ask you a question: Which religion is best (Please do not answer this question)

This is the question you have asked. There are folks here who will say "Oh Only 12 volt, Only 12 volt" and there are folks who will say "only 6 volt pairs, only six volt pairs".

The facts are basically, So long as you compare DEEP CYCLE to DEEP CYCLE there is not a lot of difference till you get to one line on the spec sheet, I'll come to that in a bit.

The thing, however, is Marine/Deep cycle.. is NOT DEEP CYCLE, it is automotive starting. the common GC-2 golf car battery IS deep cycle.

Now, that said, you can not get 12 volt golf car batteries, and I've long had access to other genuine 12 volt Deep Cycle batteries.

My recommendation is thus: Stick with a true DEEP CYCLE (Trolling or golf car) not a "marine/Deep cycle"

Now, the one spec that is often different by a big time

Cost: $80.00 (six volt at Sam's club, you need two for 230 amp hours of DEEP CYCLE power (115 usable).

Try that with the others.
