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...

well it is a matter of resistance
and if voltage is 13.6 ?
the AGM will accept more than the wet cell
How much ? difference IDK, i don't have the wet cells or equipment to properly do that test
I am trying to establish that at 13.6v (or any other voltage) the AGM will only accept more than the wet cell after the amps going into the wet cell start to taper.
I think it is misleading to just say , "At 13.6v, the AGM will accept more amps than the wet cell." If the wet cell is accepting the max amps of the charger, you can't get any more amps from the charger by swapping to AGMs
Context is everything here IMO.
That is the problem with this whole discussion
Mex pointed it out earlier
When go with a current limited supply less than what either wet or AGM can accept you have an invalid comparison of the real differences between the two constructions
There is no real reason to even do a comparison at this level
Except to establish that the wet cell will taper sooner than the agm and to a lower charge rate, and to do it at a lower voltage than either one can accept ?
ALL this does is show how SLOW charging is at low values
