We have been using the O'Reilly's for 5 years now. No issues so far.

As far as asking someone that's a good point. RVIA or your insurance carrier might be good starting points?

Home stuff on rv? Any codes? The manufacturer question relates to legalities that they may have researched.

Can you order a high powered residential solar panel system on any new coach?

Do not take this wrong. I am in favor of putting on a much larger solar system on our coach.

That and adding the gen auto start also based on temps come to mind.

Your money your choice. However I would never put a wet cell battery in a closed compartment. Let one boil over and see what a real mess is. Some folks do and that's their choice. If you where going to keep the coach for many more years and you Boondock a bunch, and you have 3-4k laying around lithium is the way to go.

No numbers. How much of the original capacity is left after how many cycles, years...

A lot less useful without measurements.

Separating the banks would seem to run into the same 85-90% to 100% double the run time it took to get from 50% to 85-90%?

My old freedom 25's owner manual mentions this issue so it recommends going from 50% max to 85% to reduce gen run time.

You large solar guys can quit reading now.

Other than large solar and sun power the only way to not damage/wear the batteries is either gels, li-ion, Lifelines and/or desulfurization electronics.

Thank you Bob, Interesting meter, if only it was that easy. Gives me something to do now, and research, battery testing. Definitely easier than running a test the way Lifeline and Roger sugest, however, Lifeline calls these and other testers, "not reliable."

I felt the best review of that meter is by ODCaveman review at the end of the following AmZon link.
Amazon.com: Battery Tester FOXWELL BT705 Automotive 100-2000 CCA Battery...

How to test Capacity (From Lifeline Technical publication)
"To determine the actual capacity of a LifelineÂ® AGM battery relative to its rated capacity, a full
discharge test should be performed. Although there are various battery testers available on the
market, such as carbon pile testers, impedance meters, conductance meters, and others, these
testers are not reliable in determining the battery's actual capacity. To determine the battery's
actual capacity relative to its rated capacity, use the following procedure:
1.
Stabilize the battery at 68-86Â°F (20-30Â°C) for at least 24 hours.
2.
Bring the battery to full charge as described in Sections 5.4, 5.5 or 5.6 as applicable.
3.
Discharge the battery at a constant current of 25 amperes until the voltage falls to 10.5
volts (5.25 volts for a 6 Volt battery). Record the discharge time in minutes.
4.
Compare the measured discharge time to the published 25A rating (reserve capacity
minutes) for the battery.
5.
If the battery delivers less than 80% of the rated capacity the conditioning procedure
given in Section 5.5 should be attempted and the battery capacity should be retested.
6.
If the battery delivers less than 50% of its rated capacity, it should be replaced.
However, the user should determine the amount of capacity needed for their particular
application and adjust the pass/fail threshold accordingly."

All good information, and interesting. But at the end day if the batteries take care of you needs great. When they quit doing that you need new ones. Your choice what kind, and how you charge them. One person opinion is just that an opinion, your pocket book and your need dictates what you purchase.

Never split the bank imo. Use one large bank.
As far as wet cells vs AGM/ gell cells, there's a reason why they invented the sealed battery. For our applications, a sealed battery is the way to go. Unless you want to mess with wet cells.
Sure the cost is lower but the hassle is higher.
Some may disagree.
But to reiterate the charging cycle of lead acid batteries can be a real hassle in my opinion. The time it takes to charge, The voltage drop with pulling large amount of amps out of it, in fact all those some companies have left out in the difficulty in charging them 100%. All left me with the desire to switch to a lithium. of course I may be biased because my started out in boats and to me lithiums were the bee's knees for that application. Going to coach's I continued with that mindset. As many others have shown AGM and/or gel cell batteries work just fine for their applications. If I didn't go with lithiums I'd probably would have went with the AGMs, although the case for gel cells is good.
I've had the Pixel 3 phone for a while now. When I plug it in it's fully charged in an hour or less. My older phones took hours to charge. And the battery had many fewer cycles.
To me it's all about the cycles. Remember with any lead acid technology you're really looking at about a 50% cycle rate. But with some technologies including wet cell, it's very difficult to get to that 100%. So then you're really dealing with only about 40% of capacity to get the most amount of cycles out of that battery. Of course you can cycle it more than 50% but you'll see a significant drop in the number of cycles that battery will deliver. Which means that you're going to be replacing it more often. That means lugging 80 to 160 lb or more in and out more frequently. on the coach that may not be as big of an issue since the battery compartment is just a door open away. On a boat where the batteries could be down in the bilge little bit different. so if you are not full-time or you are but have a good solar array on the roof or you plug in frequently then it's not an issue. If all you're looking for is a day or two unplugged using all your stuff then battery array that you're looking at will be much different than if you're spending 14 days out in the boonies unplugged. As others have pointed out they can always start their generator, that's what it's there for right? But if you don't want to use your generator often and it does seem like a big waste to just charge batteries a different system is needed.
So in the end it really depends on what your individual needs are. How do you use your coach how you plan to charge.

Actually this is what I am using to test two batteries at the same time, adjustable load up to 20 amps. Requires a separate 12volt plus or minus 5% power supply,

Not available any more from the Canadian seller. Lab grade product.

Used them to verify the 4patriots actual power capacities. Showed 55 amp hours to get them to 12 volt.

What circuits are you "powering" through that device? Temporary/troubleshooting or permanent? Kind of like a very limited capacity shunt.

As does posting battery life's info without any measurements.

Some if not most here take their coaches into some kind of shop where they measure the batteries condition on a quick handheld unit.

Versus the slower recommended way.

$1200-$2000+ worth of batteries involved. The better part of a load bank with a recording gauge is to do it during the batteries life starting at 15 cycles just to see how they are holding up.

I would hate to REALLY need the batteries to be good in an emergency and find out that they were not able to perform

While not an absolute measure of battery capacity, a carbon pile load tester is in my opinion, a pretty good indicator of battery health. I don't need the exact numbers down to 10th of an amp hour... what's more if all four of my 8D AGM O'Reilly house bank test within five percent or so of each other while disconnected and fully charged, I feel they are close enough to be equally yoked. These AGM's were always meant to be a place holder until I decide to lithium-up (or dilithium crystals

) or whatever tech looks best. I followed Foliver's posts on the Newel Guru's forum when he put in the 1000AH Balqon bank. At that time, they were about a dollar an amp hour and had I not so many other needs at the time, I would have gone for it. As it turned out, Balqon's price went up about 20% instead of going down and then they apparently stopped their US Retail business. C'est la vie... I have a 1000AMP carbon pile tester, while not nearly as compact as the hand held electronic units, I feel they give a better real world indication.

Bob, I agree with you 100%. The following video shows the Battle Born, Liion, and Ruixu being tested. I've posted this video, for those that do not understand what you are saying. Because of this video Liion changed the model number of their battery from 1300 to 1100.

Most will not want to test their batteries this way, it still does not change the fact that, as Lifeline says, this is the the only way to reliably test battery capacity: 25 amp load till battery is at 10.5 volts. Reserve capacity for new Lifeline is 550 minutes, 9.16 hrs. Reserve capacity for new Oriellys AGM8D, 517 minutes, 8.6 hrs.

This Will Prouse solar YouTube video for 5 batteries took approx. 3 days, 5 hrs each, 25 hrs., condensed in to a 20 minute video. So...Don's approx $200 tester in his above post, definitely has it's place.

What is the best price you have gotten on the oreilley AGM 8D? Its time for new batteries in my boat and these might be the ticket if I can get em cheap enough. The current flooded 8Ds wont start the engine anymore without using the boost combiner.

Around $450. less 10% military disc. $22. core if you don't have 8d's to turn in.

Most owners told me "never gave me no problem." My guru guy and I cringed as that meant watch out.

My sole point is that they still hold some charge after so many years is not much help to someone asking how they hold up.

Like my engine still runs. It's badly worn but still runs.

Like I mentioned here and from the mk engineer lots of 12 year oem gel life stories.

If you paid half and got half life that's even. But at some point the capacities were down a lot.

Versus li-ion and gels and Lifelines keeping their capacities much longer.

Pedestal to pedestal or large solar lessens the capacity needs

Carbon pile did not work at low amp draws

Don't most conventional and AGMs make it that long? Our conventional engine batteries made it 10 and our AGMs are going strong at 11 years.

Re: O'Reilly batteries

No, one of the conventional engine batteries had a bad cell but before that, the 3 batteries started the coach fine in all seasons. Wth one exception, our conventional car batteries always last 8 or 9 years without being connected to a charger. The AGM house batteries have never been flattened and run the OEM inverter fine. After I installed them, I blow off the tops with an air hose ever couple of years and that is about it. As long as they run the big TV, etc. and then the microwave/latte maker in the morning, I don't pay much attention to it. Have never had to start the generator yet because the voltage was low. I do keep both banks at 13.2 - 13.5V all the time.

They came from a bankrupt company back then and I expect a lot bankrupt companies in the very near future. Not clapping my hands but unfortunately, it's going to happen.

Solar panel prices are the cheapest they have ever been. Aside from the battery deals this week, I just noticed new Yingli 305 watt panels were on CL for $130. This is the same brand as ours, a commercial panel the same width but quite a bit shorter with even more watts. I'm sure quite a bit lighter too as our panels weigh over 65 lbs each.
