12v marine/deep cycle batteries

[AZDesertRat]

I know they are not true deep cycle and I have no intention of going to 6 volt batteries.
Which would be your choice between the Interstate SRM-29 and the WalMart Everstart Maxx 29DC? I can get the Interstates for $119 and the Everstarts for $99. They both weigh 61 lbs. I found the specs on the Interstate and its 1 year warranty but can't find anything on the Everstarts?
I am buying two to go along with my two 100w solar panels and Phocos controller for short boondocking trips in AZ with plenty of sunshine.

Yep,connected to shore power would be just fine, but I wouldn't want to try boondocking for very long.

I think Interstate is the US Battery but from factory in Mexico.
Walmart - have no idea.

I would buy trusted names of deep cycle, like Deka or Trojan. Both make 12V models. Deka also comes under a few rebranded names, don't remember now.

I doubt there is one lick of difference on the internals between the two batteries. One just has a white case, a green lid, and a huge marketing team behind it who make up all sorts of whacked out claims about their greatness.

A 6 volt GC battery is easier to fully charge, and will last 2x the amount of cycles in the same usage.

In my area the trojan scs225 (group31, 125AH)and the Trojan T-1275 (150AH) are the same price, 179$ and the t1275 weighs 18 lbs more.

I'd have 6v golfcarts if I could fit their height. But I am more than done with dual purpose car jar wet/flooded batteries.

A properly looked after battery will never require warranty 99.98% of the time. Batteries are murdered by a baseball bat to the groin applied over and over. Thicker plates of GC batteries, is like an Athletic supporter covering the groin.

It seems the vast majority of so-called "deep cycle" batteries rarely are, even those labeled as such from well known manufacturers ... here's an interesting dissertation on the subject.

If those were the choices, I would pay a little more for the interstate batteries.

Everstart DC Trolling. (no DC Starting)

I'd go with the 6v golf cart batteries, true deep cycle batteries, every time, if I was dry camping at all and off the pedestal. The Trojan T-1275 is also a golf cart battery in 12V version. Costs quite a bit more.

The real beauty is with two each 6VDC golf cart deep cycle batteries in series weighing 61 lbs each will give you 12VDC at around 220AHs for around $160... A single Trojan T1275 12V deep cycle battery weighing around 82 lbs each will give you 12VDC at around 150AHs and will cost around $250 dollars. Two mounted in Parallel will give you around 300AHs for around $500...

If you are on a budget then the cheaper golf cart batteries are the way to go...

Why rule out 6V??? It only involves buying one extra $10 cable to put them in series. Personally wont go back to 12V after having 6V for many years now.

No Walmart batteries will ever live in my coach!
