Advice?
Thanks, Jim
I like my Full River AGM's (6 volt) in my Axis. They fit under the step with Zero mods (very tight fit but will work perfectly).

One of my best mods. They Hold charge incredibly long and since I went with TWO 6v 220 amp hour I have much more compacity over the OEM Harris batteries that only lasted 6 mo.

Advantages of AGM

1. They are spill-proof

2. They have a high-power output.

Because of the way that they are designed, the AGM batteries have minimal internal resistance. This, therefore, enables them to provide sufficient bursts of power when necessary, such as when one needs to start a battery. Due to this feature, these batteries respond better to loading than any other battery on the market.

3. They have a short charging time.

4. They have a longer lifespan

5. They are durable.

6. They are unlikely to build up sulfation

I never had any problem charging them but I did upgrade my converter to maximize my results.

I don't think they are worth it!!

Ability to provide adequate voltage in cool weather overnight running heat, fridge etc

Reduced voltage drop when storing without trickle charging

Longer Battery life, hopefully

Probably missed something

When coming back from a trip I spray the batteries and compartment to wash off the road grime, let it dry, park it in the garage, come back a few weeks later and head out

I'll throw this out there...
I think that folks who don't see the advantages of AGM batteries...


... Are just hung up on rhe fact that they cost more.

I will REPLACE with lithium/next technology when its time to REPLACE.


I will not actively look for an excuse to discard my wet cell batteries.

Neither will I...
But I'll go with AGMs this time because I haven't been able to wrap my head around all of the subtle nuances that come with lithium batteries yet.

Lithium is a
Footnote
In the history of battery.
Short lived timeline much like steam powered ships.

I'll buy it due to practicalities and I already have the correct inverter.
And
They're starting to pop up used from medical equipment mandatory calendar replacement at heavily discounted prices.

I've been buying required replacement emergency-exit light, dry-cell-batteries for about the last 25 years for scuba scooters and dive lights.

I could now buy lithium surplus batteries and have really great depth charges...with saddles....

It will be interesting to watch the battery evolution since it is time for some major innovation

Getting away from rare earth elements in the battery and EV scene would be huge

It is way past time for flooded cells to go away

Truly is and perhaps change is moving faster than most if us can adapt to in many areas

Thanks, Jim
I replaced my 3 year old flooded batteries that came in my 2018 Windsport 29m with Deka AGM barreries and was NOT impressed. They exchanged them for RV & Marine Deep Cycle one's and I'll see how they do going to Texas Monday. Not worth over $120 each just so I don't have to add water. I'm looking into the Flow-Rite system!!! Bob Trice

Which converter did you get?? I was told by John at WF-Co that make the converter for my Windsport that he didn't have a better one than what was in my coach???? I'm very confused cause even Thor seems clueless and I'd prefer AGM's, but if I don't get better performance, what's the point? What brand of AGM's did you buy and where can I get a converter that will agree with AGM's??? Bob Trice

The more I read this thread added with that highly advanced electrical engineer's video; the more I have no clue as to how this is being summarized

Here is my simple way of viewing.

1. Flooded batteries, they are cheapest possible and they come with most RVs
2. AGM is an upgrade over Flooded, because they have more AHs, more reserve power, no water to add maintenance free
3. Lithium, the ultimate if you plan to boondock; or need long extended period of battery life and money not a factor.

In my case, I want the AGM because...

#1. I am very cheap (the AGMs I see are about $40 more than the Flooded) I see some AGMs are $250/$300, but I promise you, I will NEVER pay that much for AGM
#2. I don't want to have battery maintenance on my RV Checklist of things to do. That is why I bought the AGS; so I don't even have to check voltage.
#3. The Flowrite system may cost more than the differential for Flood / AGM cost, so that is not an option for me. Maybe when I first bought the RV, I should have bought the Flowrite then
#4. Getting to Group 31, increased AH, and more reserve without Lithium is my #1 priority; when time comes to replace my existing Flood House batteries.

Question:
Someone mentioned a new battery they bought that they did NOT like? Short of going dead or not being able to hold a charge (which are defects) what can a battery do or not do; to not be satisfied with? I don't think I have ever bought a new battery that do what it was suppose to do or did not work? I could see where I may change my mind or see something else I like or want, but don't see what factors make a battery underperform to expectations?

True that. And the only drawback to buying a Prevost is the cost! Notwithstanding, I get entirely satisfactory service from my cheap flooded batteries. I don’t disagree with anyone who likes other options but for me there’s no reason to pay for more than I need.

Bob,

You can solve the log jam. There are only 10 or fewer people on this thread with Flood and blocked on advantage of AGM. If you could advance all of us with $200 each max toward the set of brand new AGMs that would be just great


That is just one Tiffin payment

Bob, our entire generation has lived in a interesting time. But as interesting as it is, my father's generation saw even greater changes in their lifetime. My father was born in 1926 and lived in rural Iowa (at that time I think the whole mid-west was rural). He passed away last July having never owned a smartphone but was quite proficient with his cell phone and PC. That's a long way from no phones and the infancy of automobile and airplane transportation.

Mine was born in '29...
I should have been more specific...
It's aninteresting time for watching the development of new power delivery technologies...
