Adjustable amperage for restoring AGMs?
I was reading in the Lifeline manual about this. They say to charge at constant current of 5 percent rated 20-hr capacity until 15.6v, then continue 4 more hours. It may reach 18v, be sure your syst...

Thanks, Landy!
No, I was NOT thinking to do it as maintenance.
I was just saying that I could maybe use the same power supply, at normal 14.1-14.4 voltage, to top off batteries that prefer that voltage, after first doing the bulk charge with the 13.6 PD.
And then I would also have it if I needed to do restoration in the future.
Oh, interesting! High amps and high-ish voltage. I cannot find a 10 hour rate for my Fiamms online (I may try to call the company). IF it is 80percent of the 20 hour rate, they would want 42.24 amps per battery at the 14.7v.
I don't have anything that would do that, either, currently. The one I linked to might work for my slightly smaller old house battery, though, which is ailing and currently on a 'smart' pulse desulfator I already owned.
I was wondering about that, when the Concorde version says it takes 20 hours. I'd be willing to get up ONCE in the night to check it, but is that enough?
This stuff is on my mind because I have the one ailing battery, and I hope to FINALLY get my Fiamms this week and don't know what shape they will be in. Plus I want to treat them well.

Now as far as doing a constant 5percent of current to 18 volts regularly as some sort of maintenance, rather than a hail mary attempt to revive highly abused batteries.

Well you've read Lifeline's conditioning and restoration procedures.
Odyssey AGM has their own procedure that requires a full discharge under a high load than no less than a 40percent charge rate applied to 14.7 and held until amps taper to near zero.

Just monitor the battery for excessive temperature when you bring them over their normal absorption voltage. These procedures are not something you just initiate, then decide to go to bed.
