Bought them at Battery World here in Calgary. Think it was $110 or so each...
There's a trade off using 6 volt batteries. One the surface is sounds pretty good. However, I see some problems. The cost is higher than that of a single battery. The weight of the two batteries is 124lbs vs 48lbs for a single battery. Because there is 4 more connections at the batteries there's 4 more fail points from corrosion. Check your needs before you determine the the extra amp hours is worth it.

Yep definitely. I think it's a crazy set up for most of our trailers. I only have it because my previous trailer had inboard generator, electric bed in my toy garage, fuel pump, slide out, TV, sound system, etc!

I have 2 Walmart Group 27 Deep Cycle batteries. One in my teardrop and one in my Compact Jr. I am on my 2nd one in my teardrop. The first one I had lasted 7-8 years. When my first one died I looked around and I found they were still the best bang for your buck. I was going to by a Costco battery because when the were Kirkland brand they had a really good warranty. Now they sell Interstate and the warranty is the same as everyone else.

Deep Cycle

Hi All,

I considered two T105 Trojans for my Trillium but decided
that 120/130 lbs. on the tongue was a bit much. Instead
a Trojan SC225 Group 30H type was chosen. About 130 AH
providing plenty of power weighing about 66 lbs....

The cheap batteries from Walmart, etc, tend to go south quickly.
With meticulous maintenance my Trojan is on year 7. Present
cost is about $200... well worth it for the service it has
provided. I feel it is better to get a "real" deep cycle battery.

Happy Camping,
Larry H

We finally went with a Trojan batt for our 17 Ft SD, and I highly recommend it, much better quality battery than the run of mill rv/marine batts generally bought, its a true deep cycle and the available voltage has been well worth the switch.

Interstate, Costco, Canadian tire, Wallmart?

Getting the new trailer out just after the long weekend. Just confirmed the fridge works
I have an Interstate group 31 battery that in 7 years old and still going strong. I had it my boat for a year and then the Scamp trailer. You may want to look at Consumers report for their best battery. Most batteries are made by Johnson controls as was mentioned before. But there is a difference depending on which customer is requesting their battery be made to. Plate thickness and other items can be adjusted to make the battery more robust.

BTW if I had two battery failures in the same year I'd be looking for a cause....heck, I did that at my first failure....and that's when I ditched the converter...happy motoring
: ifyou can read that map u sent then u got better eyes than me.
We replaced the Start battery as the guy we bought it from installed the cheapest battery he could put in the MH when he picked it up from the Auction House lot in CA.
The Deep cell batteries were the same for the House cheap but we eaked out 4 1/2 years which is pretty good. We installed Batteries from Canuck tire as they are all across Canada and the warranty was good but probably not as good as Costco, I like buying my tires at Costco but they do not sell MH tires so I buy them elsewhere and we got a real good deal on 6 Michelin summer 19.5 tires, not many would of gotten what we paid 4 years ago.
We still have about 4 more years left on them till we replace them.
Hoping we sell the house first them buy that 2018 Winnebago Vista 29E we like.

just a click away Stude

just click on the pictures and they open full size.....man!...you been missing A LOT.....LOL

and Byron .... Because there is 4 more connections at the batteries there's 4 more fail points from corrosion. (????)

I didn't know that batteries failed because of corrosion at the terminals....I dunno...I keep mine clean......

and if you look at the pic...(don't forget to click on it Stude) there is only TWO more connections....to "worry" about

Actually there are fewer connections with two 6v bats in series than with two 12v bats in parallel. One jumper between the + on one and the - on the other, plus the two leads going to the house from the other two terminals. Very simple. Parallel 12 v bats require 4 wires.

Most lead acid batteries are a mystery as to their quality. But one fairly good method of deciding on a brand is to weigh them. Heavier is better. Never buy a lead acid battery because it's lighter than another brand. Some manufacturer's make very thin or porous plates that won't last long or won't produce much power. Many battery manufacturers start out with very nice batteries to build their reputation and then cheapen them over time. Finally, what was good becomes lousy. Excide, Die-hard, Delco and Motorcraft batteries are prime examples of this. Interstate may going away too.

Deep cycle batteries will always have less amp-hours than starting batteries for a given case size because they leave space in the bottom below the plates to accumulate the old lead or products from becoming sulfated. Batteries die when this material builds up and shorts out the plates. So deep cycle batteries can take abuse longer.

:to stop sulfate take a rattle can of any paint and paint the terminals once you have them all hooked into your wiring diagram for the road this is the last thing u do and u will never have sulfate problems again.

I was referring to the sulfation that occurs inside, on the battery plates.

Painting the connections only helps on top of the connector, but not on the bottom of them next to the battery and that is where the moisture source is.

Another thing I've never tried would be to put the product Noalox on the terminal before the connector is put on. It's used in electrical panels all the time to prevent corrosion.

Another corrosion problem is where the wire enters the connector or where the wire enters the insulating jacket. It can fail there and still look fine.

They sell a red and green felt washers (together in a package) at auto parts, Walmart and tractor supply stores and you put them on the battery terminals to prevent the white powder buildup.
