My 2 group 29 Interstates have been running since I purchased the camper new in May of 2014. Paid $170 for both of them at the dealer. Have performed great and we have used the you know what out of these!!! Hard to justify even thinking about lithium when these have met all our power needs. Our recent trip to Brian head for several nights in the parking Lot @ temps in the single digits pretty much put them to death :( thinking of moving the next batch of batteries (looking at AGMs) inside the camper but really have not had any issues from these.So if it ain’t broke do I just buy the same set or go with AGM’s as it is a pain the check the water levels and can possibly move them Inside etc.Any ideas on the best deals out there?Thnx in advanceNolan

Battery guys out of NV ships for free. I ordered two Lifeline group 31 AGMS last month to replace my 10 year old Lifeline Group 31 AGMs and got them delivered here in the bay area within 48 hours of ordering by fedex. Ten years of service. no way I can justify the cost of going Lithium. plus I like the fact that if the truck batteries give out in the middle of nowhere I can toss these under the hood and fire the truck right up

Is it not illegal to have a battery (or batteries) inside a camper? I had a Class B and someone added a battery inside under a seating area and I was told by an automotive repair place, that was totally illegal to have a battery inside with no venting. Maybe I was told wrong?

Another vote for Lifeline Batteries, great product.

Maybe I was told wrong?I don't doubt that one bit. I know that I wouldn't want one inside my camper.I have two group 29 Ever Starts in my camper and that's all I'll ever need.

It’s been a good run | Good Sam Community

Since it's kinda on topic, what is it that makes the 6v GC batt's better then 12v ones?

Golf cart batteries have thicker plates.

Bingo! 6 volt batteries have thicker plates and are designed for large loads and many recharge cycles.

The Golf Cart 6V batteries have huge cells comparing to automotive 12V batteries. That makes it not only cheaper to manufacture, but also more bulletproof.
What I think is also the factor that GC batteries have pretty big market, when only 2 or 3 manufacturers, so with volume and the same model lasting for decades, they perfected the design.
Automotive batteries change the designs every couple of years, so it is hit or miss.
AGM batteries are manufactured mainly for upside down applications.
Using them in automotive business is good sample how marketing overwhelmed common sense.

I’ve been happy with the pair of G31 Dekas we bought about 8-9 years ago. I’ll probably replace them soon to be safe but they’ve worked really well. They are plugged in in our Lance outside 24/7/365 in the mountains and have been fairly regularly abused and run pretty low.

6v Golf cart batts have performed so superior to 12v whatever. I can't imagine any other way now. The deep discharge capability is non-destructive on purpose.

I have very limited clearance at the top of my 2 battery compartments so I switched to two 6 volt AGM's not only due to no maintenance but also because they are any-position batteries so I can have the terminals facing outwards for much easier hookup.

Start loosing capacity at 10 years mark, but I used couple of them till 12 years of age.

....my old Maxtanks (AGM) are still in operation at 13 years last year (2020). I suppose replacement will be needed soon.

These are the same as mine. Same specs and dimensions. Made by East Penn w/Duracell label. I paid $180. $130 is a dang good price. Hopefully they have a decent warranty. At that price, get 3 or even 4 of them. Find room if you have to. Sure would be nice to have 420Ah's.
One thing they seem to do well is recover quickly.

Thanks for all the replies, I was looking at getting the lifelines and almost pulling the trigger, but these blems (don't come with handles) caught my eye , anyone have any experience with DEKA's?

Yes, I put Deka group 31s in my Arctic Fox 811 in 2015, THey are still going strong.

Here's that upgrade project

I HIGHLY recommend a good amp hour meter too. I run a Victron BMV 712.
