I got to the point in charging that the 2 amp setting for a few hours (with a very small draw) the voltage fell down to 13.55v, but the 8 amp setting creeps up to 14.65v at 3 amps (my max charge spec is 14.6v). The 2 amp setting on the smart charger is running at 14.08v -14.21v (runing up and back a few time a minutes, toing the smart charger sulfation reduction dance), so I will let it go for a few hours then take a resting voltage.
Ah, if it were only one battery--but you see it is NOT for me. So if I am not careful I end up ruining potentially 8 batteries. The better they match each other--the less likely I am to have a problem.

I haven't had any coffee in 40 years, can I drink hot tea.

Yes! Tea would work. About 25 years ago we had a procedure for assaying amount of Caffiene found in our products. Had been used for years, but one day one of the chemists wanted to see who was getting the most Caffeine each day from drinking: coffee, tea, or pop.
After testing the pop one out "hands down", tea came in second, and coffee third. With tea you will wake up faster and get the brain in gear faster than coffee. The pop users are good after the first can.

IF they are for house batereis on an RV, you should look for DEEP CYCLE without the word MARINE in front of it. Marine/Deep cycle are starting batteries, not much different from what gets you to the store. DEEP CYCLE are what you want for house work. This applies to AGM as well as other types.
Nope!
AGMs are hybrids. The only AGM that I have found that specifies starting only is the Optima Red-Top.
If you look at wets on a scale of 1 to 10 where 1 is DC and 10 is SLI, then AGM will be in a 3 to 8 range except as noted above.
Deka tends towards DC(3) and Sears Platinum-4 AGM tends toward SLI(8) when measured in AH or CCA per lb against wets.
I have not yet found an AGM spec that can approach a pure DC(1) wet spec like an L-16.
The only difference between DC and SLI with Marine/Automotive AGM, within mfgrs, appears to be with the terminals, and not the plates or case. E.g., the Sears has Marine/Auto versions of the P-4 and they have identical AH and CCA specs.

P.S. I meant to say an L-16 would be in category 1, or the pure DC end of the scale.

I am in LRGV and the Sam's club in Mcallen, TX has 100AH grp 31 AGMs for $168. The label says Johnson Controls.
So Yes, there seems to be some movement towards lower AGM prices.

The AGMs seemed like a good deal but the word is lead prices are headed up which could drive all batteries to be more expensive. I wanted to get mine before any price increases hit.
