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...

Hi landy,
BFL13 would call this progressive capacity loss. I'd call it reversible sulphation.
I LIKE your aim.
Yes the partial recharges are the bane of AGM. That's why they may require BIG amp recharge and may not be well suited to the "low and slow" solar approach.
Surplus acid AGM don't require the huge amp recharge to "wake them up" and in fact may be damaged by it. Hence the c/5 limitation on recharging. I'm hoping they are better suited to low and slow.

Lots of low and slow recharges until 92% and then if 40 amps are then applied( to a 90Ah battery) amps will start tapering much faster than if the day before had a high amp recharge until 100% was achieved.
I Aim for no less than 95% and 100% every 5 cycles.
So how much partial state of charge cycling has been going on, in my opinion, will have huge impacts on when amps begin to taper when held at absorption voltage
