Hi,
Gel batteries are not well suited to RV use.
I'd pick the largest amp-hour capacity AGM that fits in the available space.
Regards, Don
My ride is a 28 foot Class C, 256 watts solar, 556 amp hours of AGM in two battery banks 12 volt batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

I have a group 31 VMAX Tanks AGM that’s 5 years old, and without any scientific data, charts, graphs or logs to support it I can definitively say that it’s still going strong.
Bigly strong in fact. ![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/awink.gif "awink")

How about this one? I know nothing about it, except it is cheap for a group 31 AGM.

I’d be suspicious of that one. It’s awfully light for a group 31, and the amp hours are low.
It may not really be an AGM. They use the acronyms SLA, AGM, and VRLA in the description. SLA and VRLA can be used interchangeably, but AGM is a particular type of SLA that will have specific construction inside.

What you do with your camper to require something like that?
What Buzzcut said mostly..Putting batteries in the wheel well makes it very difficult to service and the heavier the battery,the worse it is to pull it through that tiny opening..LOL
I was going to go 6-volt but the same problem exist unless I went AGM 6-volt and there really spendy..
My main reason for another battery is for my Engel compressor fridge/freezer..I want to be able to move the battery at will to where ever I want the unit and not worry about ventilation as much.The Engel only pulls .67(rounded up) amps per hour as measured by a RV.Net person (2manytoyz)that measured the exact same unit I have at 18 amps in 27 hours...So even a group 24 AGM would work just fine for a couple days without going below 50%..
There is a new deep cycle battery out I had never heard of,MotoBat that has some impressive amp hour numbers for each group size,but it is spendy also and not knowing much about them I am leary of spending that much on one..
Lifeline are expensive but it appears there worth it..I will be looking for a special on them in the very near future.

That battery is made offshore, I would much rather buy “made in America”, and support American workers.

It lets you put a battery into a tight space where adding or checking water would be a royal PITA. Mine are crammed in at angle and it was install and forget. No watering systems or any other thing to bother with ever. It's a "Keep it simple stupid", solution
just buy a battery watering system. I got mine off amazon (Canada)for 50 bucks. makes it easy as heck to top off water, I am even going to order a 4 GC set up for my 5th wheel now for the pure convenience.

you are still thinking of the batteries in a vertical orientation, AGMs can be stacked on their sides or tilted and need zero attention

I found some reviews on Amazon where the purchasers claim to have tested the battery, and it only provided 50% of the rated amp hours.

I've been using Deka AGM batteries, size 24. First set lasted 8 years but most of that time was with the crappy charger which came with the camper. I upgraded to a 3-stage charger compatible with AGM batteries so I'm hoping the new batteries last longer.
