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...

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.
Thank you for the suggestion. I wasn't able to do any testing yesterday, and only have a few hours today. (I'm kind of stressing about this situation.) Your quicker test will be easier for me to do today. I'm wondering how much of a voltage rebound I should be looking for, but I guess I will just post my numbers when I'm done and see what you all think :-).
I have a meanwell that will do up to 30 amps, so I can top off the batteries while I am there too babysit it.
Where is our dear Mex? He doesn't usually miss a battery conversation, and this worries me. I hope I have not missed some horrible news.
