Do AGM's charge quicker?
Looking to cut generator time. Have solar but sometimes have little to no sun when dry camping. Read AGM's charge up to 5X faster than flooded. How can that be, converter charger only puts out so mu...

FWIW, here's the two internal resistance specs for my favorite two Group 31 12V AGM deep cycle RV batteries:
Lifeline, 125AH, model GPL-31XT = 3.03 milliohms
Fullriver, 115 AH, model DC115-12 = 3.80 milliohms
As can be seen, the Lifeline model is a tiny bit "superior" in the low internal resistance contest. Overall I have no doubt that the Lifeline may also be a bit better battery in other areas - versus the Fullriver model I chose for our rig.
They're both expensive AGM batteries, but I chose the Fullriver over the Lifeline because of the Fullriver's higher specified float voltage range so that I wouldn't damage it from year after year of exposure to my RV's stock Parallax converter's fixed nominal 13.8 volt output.
By the way, I'd sure like an (unbiased) battery design engineer to explain what construction techniques employed by Lifeline over those employed by Fullriver make for the Lifeline being able to take larger charging currents than the Fullriver ... other than that arising from their slight internal resistance difference.
