12 volt deep cycle batteries

I priced them .. They are 89.99. Plus tax in NJ comes to 109.98. ( without 12$ core) Minus 10% = 99.38.

There is a core charge of 12 bucks. Need an old battery to bring in..

If you have one 12 bucks off above price. 87.38..

Then a 10 buck mail in rebate.

77.38..

I just got an Interstate battery, SRM-29, 675 CCA, 210RC for $108. Should be more than enough to run my inverter for my small dorm fridge on the road.

The Duracell 24DCC is not a "true" deep discharge battery. It is a dual purpose battery. Good, but not as good as a "true" deep discharge battery.

It is hard to find 12V deep discharge flooded or AGM batteries without special ordering them. And they are expensive. This is why so many people are using two 6V golf cart batteries, if you have the space. These ARE "true" deep discharge battery and they typically in stock and are very reasonable priced at either Sam's Club or Costco.

wasted effort

I agree with the theoldwizard1.
However if you just need something while you roll between pedestals it will serve you well.

If it is NOT a cranking battery why do they advertise both Cold Cranking Amps (CCA: 500) and Marine Cranking Amps (MCA: 615) ?

I'm just going by what the rep told me. Like I said, it's not a debate between 6v and 12v, deep cycle or starting. Why do you people have to turn every post into a pissing contest?

Because the forums are populated by a bunch of lonely old men who think they know everything about everything. Don't believe me? Mention Diesel, Walmart, Harbor Freight, Half ton, Hitch, or Generator in any of your posts. If you want to find out what they think is best, just check their profile for what they own.

TomG2...Well said.

I just ignore the 6V golf cart battery crowd's fanboy comments, too. 12 volt Group 24/27/29/31 batteries are the only ones that fit where batteries belong in our RV.

That being given and since I want to use true deep cycle batteries, I have to budget for the extra cost of either true deep cycle 12V wet cell batteries or true deep cycle 12V AGM dry batteries.

Trojan and a few other manufacturers offer true deep cycle 12V wet cell batteries, and several manufacturers offer true deep cycle 12V AGM dry batteries.

However no matter what type or what manufacturer of (new) true deep cycle 12V battery you buy - they will always cost more than the easily available and inexpensive common 6V golf cart type wet cell true deep cycle batteries or the common 12V marine non-true-deep-cycle batteries that are found everywhere.

It's as simple (or complicated) as the above ... unless you opt for the ultimate and can pickup used 6V or 12V true deep cycle AGM dry batteries that are both cheap and have plenty of years left.

I saved up our money and installed a couple of new Group 31 true deep cycle 12V AGM dry battteries that hopefully will give me at least 6-8 years of hassle-free service.
