Hmmmm .... I just drove down into town and picked up a couple of the Fullriver 12 volt deep cycle batteries from a solar equipment distributer. I drove no further than the local Walmart or Costco stores would have been.
I believe that Lifeline batteries may be fairly easy to locate, too.Huntindog wrote:

If you are allways on FHUs, then 2 batteries of ANY type are a waste of money.

I didn't realize that Trojan batteries were considered as "rare". Here's a (almost Group 31 size) Trojan flooded 12 volt deep cycle battery that, in fact, weighs 82 lbs.:

And for those who want to step into the AGM world here's three different 12 volt deep cycle batteries of about Group 31 size, all three of which weigh 72 lbs. on up:

We use two of the above Fullriver 12 volt batteries in our rig, for a total storage of 230 amp hours and total weight of a little over 144 lbs..
At least you aren't disputing the cost difference.SoundGuy wrote:
This being the case it therefore stands to reason that equipping a trailer with dual 6 volt deep cycle batteries is highly overrated as most owners would rarely if ever fully take advantage of what those 6 volts have to offer and would be just as well served, if not better served, with a pair of 12 volt versions offering similar AH capacity.
According to your logic, most people would be even better served with the smallest, cheapest SINGLE12 volt they can find.

- Hi soundguy,
You truncated my post. Here is the rest.
"The true answer is "it depends". There is no one perfect battery bank, there are systems that do meet the needs of the user. In my case that has always been 12 volt jars." pianotuna wrote:
While it is true six volt jars have thicker plates, they also have to work twice as hard, and do exhibit more voltage drop under large loads (such as running the microwave via an inverter).
The majority of parks in the Ontario provincial park system (second largest in N America, second only to the US National Park system) offer on average 1/3rd electric sites and 2/3rds non-electric. In recent years when any park has been upgraded or newly built almost all the new sites are designed with electric service and the reason is obvious - camping for most has changed significantly over the years and beyond anything else the vast majority of campers today insist on the convenience of having shore power. During the summer months it's quite difficult to get an electric site, particularly on weekends, unless one has reserved 5 months in advance ... but non-electric sites are almost always readily available, even last minute on a first come, first serve basis. I've also found the same generally true wherever we've camped in the US - the vast majority of us want electric power, even if it costs more. This being the case it therefore stands to reason that equipping a trailer with dual 6 volt deep cycle batteries is highly overrated as most owners would rarely if ever fully take advantage of what those 6 volts have to offer and would be just as well served, if not better served, with a pair of 12 volt versions offering similar AH capacity. That certainly would apply to my own situation and whether they admit it or not I believe also to many other RV owners who mistakenly buy into the "6 volt is always better than 12 volt" argument simply because it's repeated over and over again on forums like this. :Z Better to understand what your needs really are, then match the battery bank to that need ... geez, what a concept. :W- The cheapest people on the face of the earth are owners of golf courses. Wanna argue battery type worth go argue with them. They'll fall to their knees laughing if you staunchly defend RV six-cell batteries.
"Man! It works for ME! It's stupid to think MY choice won't work BEST for EVERYBODY!" I iz a ekspert garrunteed! I likes GIN! Therefore itz the BEST! So is my brand of car, where I live, my choice of presidential candidates - oh de list is endless...
Three cell versus six cell is not comparable. Each has its own SEPARATE attributes - advantages and disadvantages. It's not a "My Orange Is Better Than Your Apple" debate. Choosing blindly for somone else is Ignorance Incorporated. - For those that missed it the 1st time, I'll post it again,.......
Here is the above 3 pages all combined into 1 post,....

And w/o getting all technical,....picking each one apart for stupid little reasons, if you do not abuse them, keep them watered and charged, you will not find a dimes worth of difference between 6 & 12.
So whichever is the most AHs for the money, go for itRJsfishin wrote:

Over the past 20 years, I've had 12'ers, then I had 6'ers, and now I'm back to 12'ers.
