AGM vs Flooded Bulk Times
PT keeps asking whether AGMs will spend more time in Bulk at the same charging rate. I found a good example where that can be measured, using ah64id's test with his PD4655 on his pair of Lifeline...

My attempt at 1st and 3rd factor resolution apparently worked. Thank you Mr Wizard for seeing unresolvable factor 2.
When time is -the- component to be resolved both E and I must not be limited to less than calculated values.
This is why as an engineer I insist on dealing with resolved kWh totalization.
i.e. induce say 1.0 kWh into each type of battery. How long timewise did it take using identical voltage ceilings? Try incrementally from 12.1 volts to <1% amps woth AGM or until flooded unit recovers original gravity.
Idiosynchocies between charge methology can only remain a matter of curiosity. Arrival at defined full charge levels are I, E, plus time constant dependent. Of the components E is by far the easiest to control.
As I say again and again ad infinitum...
Is spending a mere hundred dollars worth gaining twenty dollars in added battery lifespan? Fuel doesn't get delivered to your campsite and genetator wear and noise can care less about your compassion for extending battery life to theoretical optimum value.
Are imaginations running amok pondering such inconsequentials as ramifications of imposing .4 differential controlled voltages? This stuff is not quantum physics. The answers are known. Research then employ the protocol and regimen best suited for your batteries and usage.
Connecting to a power pole makes moot the above.
It took Trojan what (?) 20 years to get a grip and arrive at 14.8 volts corrected and publish it rather than dismiss it as being irrelevant to users. R&S at least goes as far as defining performance / lifespan ideals. Keep in mind 5% of a $30,000 bank isn't chump change.
Enough for now :)
