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...

There are those who would say 13.6 won't ever charge a single battery fully.
I used to charge 875 amp bank of flooded cells with a 35 amp PD with wizard. It took a long long time (a week on shore power) but it would eventually get there.
But for you to check if they are junk--charge as much as you can tomorrow, then the next day put on that 900 watt and 600 watt heater (if the inverter can do it). Look for voltage to go down. Run it for ten minutes. Disconnect the batteries from each other. Wait 20 minutes then check to see if the voltage has recovered. If it has the batteries are ok. Do be sure to recharge before you leave on the second day.

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.
