Maximum amps for testing AGM capacity?
After a winter of being very sick, and a spring of catching up on farm chores, I am finally back to being able to work on the van at least once in a blue moon. Next step, testing the 100aH Fiamm telec...

Yes, as MrWiz implies, I am not up to rigorous, scientifically valid testing right now.
I just want to find out: 1. If any of the batteries are junk, and 2. Which ones have similar charging and discharging characteristics, so that I can connect them in pairs.
I don't think I can put all four batteries in one bank, because I don't have proper charging capacity. I have an 80 amp PD.
I appreciate the comment about watching for voltage that crashes.
Is there anything else people think I should try to learn from my funky testing, that would help me with my build? I'll be able to mess with them for an hour or two today, and a few hours tomorrow, and then I won't have access for a few weeks.
You can do a test to see if the batteries are any good at all, but that might be all you want to know.
If you put a load on them and their voltage does not "collapse" but goes down in a regular way, you are good to go.
