Deep Cycle or AGM battery thoughts needed!

Good question.
As some have said here it is hard to beat Costco Golf cart batteries for the value. A true deep cycle battery.
Compare price and Amp hrs.
Costco: 6V Group Size: GC2
Part Number: 9-GC2-UTL
Voltage: 6
Reserve Capacity(RC) @ 25Amps: 105
Reserve Capacity(RC) @ 75Amps: 175
Amp Hours(Ah) @ 20Hr: 210
Amp Hours(Ah) @ 5Hr: 175
Length: 10 5/16"
Width: 7 1/8"
Height: 11"
Weight: 58lbs
Your Price: $98.99
Lifeline: RV Battery Specifications. Also rated as Deep Cycle battery.
Voltage 6v
Length - in 10.28
Width - in 7.06
Height - in 9.92
Weight 66.00 lbs / 30.00 kgs
Lifeline Battery
Part Number: GPL-4CT Cold Cranking Amps: 1095 Rated Cap.
Amp. Hrs: 220
20 Hr Rate Minutes of Discharge
68° 32° 0° 25 Amps 15 Amps 8 Amps
GPL-4CT 1095 925 750 220 492 856 1692
Your Price: $309.50
FYI, I have been told that Optima is no longer the same company and to steer clear. They have down graded there warranty and are no longer made in the USA. Many new failure issues.
Many folks are converting to Lithium batteries now. They are significantly lighter and significantly more expensive. However in the long run may be even more cost effective. IDK.
All this being said. I have four of the Lifeline GPL-4CT batteries in our Safari that have lasted for 10 years. Pretty good value I would say.
Best of luck,
-Dennis

The Optima configuration has lower capacity than the standard batteries so that is out for me. I do not think the AGM provides more power. The golf cart batteries might provide more usable power. But if they do not fit and you have to rewire they require some effort. I am also buying batteries this year. Have not decided yet. Looking fondly at the possibility of lithium batteries.

From my perspective the answer is pretty straightforward, though I suspect that most of the respondents to your query will disagree with me. Your useage and battery care is similar to mine, i.e., rare dry camping and proper charge maintenance; consequently, high-priced batteries would not be cost effective. If I continue to get a decent number of years out of the Costco/Interstate, etc. hybrid RV batteries, then that's what I'll continue to use. If not, I'll switch to group 27 automotive starting batteries because they have a longer guarantee. I'm also thinking I might just use one battery, rather than two since I only need battery to operate the water pump during brief pit stops. An automotive starting battery will serve that purpose without difficulty. I did use a single battery for one season, and it worked perfectly fine...I just insulated the connectors of the unused battery compartment.
I hope this helps.

The only real advantage to going AGM is maintenance. Or lack there of. No need to worry about water levels etc. obviously charging correctly and winter maintenance charging remain the same.

My previous trailer had a 10+ year old Lifeline AGM that was working great and my current trailer has a pair of 6 volt Lifeline AGM batteries which are doing very well. I find they are very dependable, do not out gas and are maintance free.

I agree with this. You already have your battery routine down with the flooded cells, it seems to work for you (7 years life), and you mostly have full hookups.

Well, went to the battery store this afternoon. I had a very good discussion with a very knowledgeable sales and service person. At the end of it all he suggested that the Deep Cycle flooded battery would be my best purchase, based on my maintenance schedule and type of use. I brought 2 new one's home. Thank you all for the insight and thoughts. If the price of the AGM's was closer to the Deep Cycle, I probably would have gone that way. Tomorrow they get installed!

I have a 2016 AS that I bought new and soon thereafter I replaced its lead acid batteries with Group 27 AGMs that I bought on eBay for around $175 each with free shipping. They're still working just fine five years later with absolutely no maintenance except a trickle charger.
In 2011 I bought a twin diesel cabin cruiser and replaced all of its batteries (engine starting, house, generator starting, & bow thruster) with AGMs (at approx. $4K), and they are still working just fine, again with absolutely no maintenance except a trickle charger.

Your choice is a good one, basically because you take care of your batteries. Many owners don't, then wonder why their batteries fail. You, on the other hand, are a good caretaker.

New batteries are in the trailer. Before I installed them, I got thinking of the orientation of the positive post. The positive post has always been closest to the compartment door, and with the Group 27 batteries the clearance when removing is very tight. A couple of times the rubber post cover has move when pulling out the batteries to check them and have had an arc. I have always bee
n taught to remove the negative post first, then the positive. Looking at the cable length in the compartment I was able to install the batteries with the negative post closest to the access door. Now when I check the batteries, I can disconnect the negative post and not have to worry about an arc. I guess that you are never too old to learn something! Thanks again for all of the input. Chris

AGMs are preferred by off roaders as they can handle the shocks of rocks and bumps better than sealed lead acid. Unless ur going down bumpy roads at off angles, the cash savings of deep cycle SLA will be just fine in ur coach.

Hi
There are three basic choices:
1) The cheapest flooded cells on sale at Costco or your favorite outlet.
2) AGM's from a variety of suppliers.
3) Lithiums (also from a range of suppliers).
Looking at immediate cash outlay, number 1 wins hands down. For a "never use battery" use case, this is also the winner.
Looking at long term cost or at performance, number 3 wins by a wide margin.
AGM's used to be the "long term" winner. These days ... not so much.

Five years ago, I too went with lithiums, solar, and an inverter/charger. Today, I realize that system is by far cheaper and more reliable than either the flooded cell or AGM systems in the long run. Zero worries and complete reliability.

We have used the Interstate flooded batteries since 2007. Each set lasted 7 years. With a 100watt portable solar panel, we're good, we have low electric demand. We've gone eight days (until we ran out of water). I'm putting 280 watts of solar on the roof as soon as the parts arrive. I also need new batteries and see that Interstate now has "EFB"- Enhanced Flooded Batteries. Wet, but no maintenance, claim they double the life. I'm not expecting (or wanting) 14 years out of a battery, but I'm interest to see how they work.
