??? 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...

They pay me, I'll document it. Señor pnichols.
I already advised them. As far in as I got was
"Raising the float voltage would conflict with mil-spec values which have been in place for three decades"
Not losing one gram of hydrogen and oxygen, plus temperatures averaging <1F versus ambient tells the whole story. Whether a person takes this FINDING seriously is their personal choice. There is a hell of a difference between opinion and finding.
PS Because I am getting ready to move to warmer climes and here yesterday temps were 91/70 I put a 500 ampere shottkey rectifier in series with the WFCO power supply and the voltage is now reduced to 13.4 float. Voltage will be reduced to 14.3 during booooooooooost but that's fine.
Test your "special voltage" brand of AGM yourself. An AGM battery has a voltage ceiling in which amperage drops off rapidly to a tiny quantity. 14.4 or 14.8 volts do your own test and see exactly where voltage-wise this happens. Charge at 14.4 volts until the ceiling is reached, then crank up voltage and see for yourself amperage (increase?) coupled with length of time before the 14.8 charge limit hits the ceiling. If it's a very short time, then the higher voltage rate is a MOOT point.
This is why large manufacturers clandestinely hire outside engineers. In-house engineering staff members get brow-beaten by the senior staff engineer so their points are ignored. When warranty claims started to climb, my telephone rang. I reported to senior staff not the engineers. Senior plant engineers treated me like I was Hannibal Lectur and Benedict Arnold all rolled into one. I dealt with facts, not office politics, peer pressure, or sea-lawyering.
