??? Set Points For Different Battery Types
I'm just learning, with a smidgen of comprehension thrown in, set points for charging batteries. Are the set points the same for ALL AGM batteries, for ALL FLOODED/WET batteries, for ALL GEL batter...

"Thrive" ?
"Do Harm" ?
Is the text of my writing above invisible?
When Lifeline wrote the SPECS for their absorbed glass mat batteries they constructed ONE (that means unique) charge protocol. That PROTOCOL is designed for MILITARY SPECIFICATIONS. Few individuals have the faintest conception of the meaning of the phrase MIL-SPEC. it is not only hard copy traceability of raw materials, construction, finished materials, assembly line members, verification of test parameters and equipment accuracy, but a cast in concrete GUARANTEE of lifespan. MIL-SPEC puts a manufacturer on "the spot". They cannot BS or Bluster their way out of non compliance.
Absorbed Glass Mat battery sales is a cut throat industry. As such OEM demands customers do everything but stand on their head to make their product look as good as possible.
Theoretically IDEAL environments meet that goal. Theory and Reality are not synonyms. So REALITY goals have to be focused on and judged whether or not reality and idealism can have a happy interface. Still with me?
Battery engineers have to publish "something" that pleases management or they find a pink slip sitting atop their desk. Management is psychotic about any "official" inference that makes their product look anything less than THEORETICALLY perfect. Still there?
"Uhh Harold, tell me WHY you had the audacity to publish public literature that OK'd a battery management technique that exceeded our optimum "X" float maintenance voltage value? You told me specifically that (13.25 volts) was optimum, yet you went ahead and declared (13.6 volts) as being 'within acceptable limits'. Did you lie to me when you at first declared 13.6 volts float maintenance would reduce overall battery life on average by two to three percent?"
The question is time, amplitude relative. Positive plate erosion is the single, solitary issue with this point.
Are you, the customer, willing to stand on your head, to gain 2-3% more battery life?
Drop your complaints about temperature compensation. Temperature compensation is vital but it is totally moot here, because this issue is about BASE voltage application, not temperature which as mentioned is vital.
This old engineer is too cagey to fall for Techno-Porn. Delta T thermal loss (That's BTU's) weight loss, in conjunction with E and I calculations tell the entire story.
This is FAR BEYOND what the average consumer wants to get involved with. So is the heavily insulated 14" X 6" X 9" box I constructed to measure Delta T thermal gain with the DUT. Energy is never lost - the fundamental of physics. It is translatable. Weight loss, BTU emission, in concert with voltage and current interpretation is not now, never was, and never will be a arguable point.
No a 97% lifespan is not maximum "thrive". Only a fool would claim otherwise. The question is 'Is Thrive Relevant"?
Thirteen point six volts maintenance will abruptly destroy an AGM battery at -30c and will similarly destroy an AGM battery at 60c.
You wonder about why I wax eloquent about .105" plates. Now you know the positive plate erosion factor associated with elevated float voltages.
If you want genuine hocus-pocus, visit health and nutrition websites where they have refined the art of snake-oil exaggeration to the point of incomprehensibility.
If AGM batteries were as fragile as a Hungarian actress' ego, tens of thousands of underhood AGM batteries would have bitten the dust.

Search for the AGM manufacturer who advises to not purchase their product for underhood use. Try and find an automobile that does not have Death Valley Dottie grade battery environment, and alternator voltage regulation that comes within LIGHT YEARS of VITAL AGM battery recommendations.
I fought battery hocus-pocus for 30 some odd years. I never lost a confrontation but I caused a lot of red faces and hard feelings. Car batteries are warrantied longer than flooded RV batteries. Do you see a warranty difference between automotive and other usages?
