Unfortunately, it appears that it's about time to replace our five (5) year old House batteries; maybe also the Coach's - 6 or 7 yrs old.

We currently have four (4) LifeLine AGM, Deep Cell, model GPL-4DA - 210 AMP each.

With all the new technology available: AGM, Lithium, etc., THOSE OF YOU WITH BIG RIGS what are you buying?

How long have you had them installed?

If you had to do it over again, would you buy the same ones???????

Golf cart batteries provide the most power for the buck. You should be able to fit 6 GC2 batteries wired in series/parallel in the space where four 4Ds went. That will give you 660-amp hours of capacity.

GC2 batteries can be bought at Costco, Sams, Batteries Plus for $100-150 each.

BTW, coach and house are the same. I think you were talking about the chassis batteries.

[Mod Edit]

Lithium offers lots of advantages, and the price has come down substantially, but is still more expensive and there are other issues to consider, like can your charger fully charge them and your alternator may also not fully charge them, and you need to make sure they don't pull too much current from your alternator when they are at a low charge state. So Lithium is awesome, but is not a simple swap and go proposition, tends to be more of a project.

Ditto: Take lots of pictures first and remember to remove shoreline.

When we bought our ‘02 DutchStar 10 years ago I had installed a full set of new Interstate batts… a pair of Gp31 AGMs for the chassis, and four GC2 flooded for the house. I never got obsessive about them, but I did check fluid regularly on the house set.
As usual (in my experience), those Interstates just kept humming along without a burp. At the end of summer in 2020, after 8+ years of flawless operation I felt it was time to replace them, purely on general principle. I replaced them with another full set of Interstates, but this time with AGMs on both sides of the rack.

Since I was cought in the desert (off-roading over new years) I wound up going to two of the local Walmarts and bought six (6) "29 series" at about $120 each) and two (2) house batteries (at about $100 each). All fit nicely and all is working very nicely.

Alls good that end... GOOD!!!!

Check back with me in three/four years and I'll let you know how they're holding up.

Researching batteries is about as much fun as a root canal. Not to mention the sticker shock for some of the lithium based batteries. A lot comes into consideration like space and what will work with your current charging system. You might find that your inverter/charger won't work with some of the new batteries. Where I can help is Richard at High Tech Batteries is a great resource. Knows a lot about batteries and had the best prices on the AGM batteries I went with. https://www.techbatterysolutions.com Good luck!
