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 single 100AH AGM batt is not in the 5er where I could easily run this test using the Trimetric.
As far as faster charging, its spec says charge at 27 amps, so that is no advantage over a flooded battery in that regard. It is not a Lifeline!
Charge Method (Constant Voltage)
Cycle Use (Repeating Use)
Initial Current 27 A or similar
Control voltage 14.5 - 14.9
Float Use (Control Voltage) 13.6 - 13.8
It could well be that it would still recharge faster than a 100AH Wet using a 27% charge rate just from holding the 27 amps to a higher SOC than the Wet. Don't know. Huge PITA to haul it out of the TC and set up a trial set-up in the 5er. :(
It was PT's question, but when he first asked it, I suggested he run his own darn test since he has all the necessary gear to do that. No such luck! Oh well, he is owed something for looking up a bunch of stuff over the years. :) But not to the extent of hauling out my AGM from the TC and all that. Sorry! :)
