AGM Charge Rates and Times
I am interested in knowing how fast AGM deep cycle batteries charge, especially in the upper SOC range. Things to consider: - Ah Capacity of battery/bank - starting SOC or DOD, or Ah's consum...

Last night I took 55 AH from my screwy flooded 31
At 9 AM the solar had voltage upto 12.6v
I set MW to 13.9v and plugged it in.
18 amps began to taper immediately
When I cranked it upto 14.9v, 40.95 amps
Comparing this with the AGM which had 30 amps removed, the AGM took 22 amps at 13.9v.
So at least in my two batteries, the AGM does indeed accept higher amps at lower volts. I don't know how much faster it would charge overall to 80% to 90% or to 99%
But again, the flooded battery has 330+ cycles on it, the AGM ~ 30. So it is hardly a scientifically accurate observation.
