12 volt sealed batteries, for house bat.Pro/Con

[chucl66]

I need to replace my house batteries,2 6 volt, wet cell.
From my previous post, some suggest using 1,12 volt deep cell. We do not dry camp.
Would like to hear from those that are using this configuration
Have narrowed search to, Duracell, Interstate, AGM, 12 volt deep cycle.
Both are equal in reserve power.

Thanks,
Chuck

Replaced with 2 Interstate, 6 volt.

Thanks for the help!!

Pros and cons of Sealed Valve Regulated Lead Acid over Flooded wet cell.

Pro: Little maintenance (They say Maintenance free but they still need some terminal cleaning every few years).

Cons: First, most MF batteries sold for RV use are Maine/Deep cycle, Marine/Deep cycle are NOT deep cycle, they are starting batteries, though they can safely go slightly deeper into discharge than a automotive starting battery. but 50 percent is a seriously deep discharge for them, it is the recommended minimum charge on the flooded wet cell GC-2 Deep cycle.

Cons: Higher cost

Cons: Lower overall life in many cases.

So for the best "Bang for your buck" GC-2's from Sam's Club may be the best buy.

Hi,

A 12 volt marine battery will be fine. A sealed lead acid 12 volt battery will also be fine. You do not need the expense of twin six volt batteries.

AGMs are specifically designed to be used as drop-in replacements for the older flooded battery technology. While costing more, besides longer life and a host of advantages over other types, "you get what you pay for". 🙂

Battery info you Need 2 Know

Thanks for all the help. I think I will replace the two 6 volt, with the same as I had.

Thanks again.

If you never dry camp I'd get the cheapest group 24 battery you can find. It simply won't matter.
Why spend the extra money for an expensive AGM when you don't need it?
By the way, AGM batteries are different than gell batteries. While both types require different charging voltage than wet cell batteries AGMs are almost the same. Just about any normal charger will work with an AGM. This is not the case with gell batteries.
I see no reason to even consider gell batteries in an RV.

12 volt deep cycle batteries are available everywhere. Not to be confused with the hybrid "deep cycle/starting battery", which you do not want.

AMEN, on our last MH I replaced the house battery with a gel. It charged at a different rate than what was specd for the charger. Ended up causing a host of problems one of which was destroying my chassis battery since the ALT tries to equalize charge over both and over charged it. Very costly mistake. Battery warehouse swore that was the best to get, apparently they no nothing of RV charging systems.

We do dry camp for a few days on occasion, but mostly have at least an electric hookup. Last fall I replaced our two 12-volt maintenance free Walmart group 24 EverStart Marine coach batteries with Walmart group 29 MAXX Marine batteries. The batteries I replaced had been in service since 2005. The new batteries were made by Johnson Controls, the same company that makes batteries for Interstate.

You can use a smart(auto) charger on gels.

True Deep Cycle 12V are very expensive and difficult to locate.

If by sealed, you mean truly sealed like GelCel or AGM, the only disadvantage to these is that they are expensive.
The advantage is that no maintenance is ever required (actually can not be done) until replacement.
