Got my new (used) batteries!! Now, how do I rejuvenate them?
After a YEAR of Murphy's-law delays (his health, my health, getting stranded on the way there, etc., etc.) I have finally got my hands on 4 Fiamm 132aH, Just like Mr Wizard's.
I figure I should check in with you guys 1st, rather than just stick them on a charger.
They range 12.33-12.68 volts right now, with no load. I think the middle two were 12.49 and 12.66.
The Fiamm spec sheet says they like 14.1-14.4v charging, 13.62 float.
I have a PD9280 and a NOCO gen charger that puts out 10 amps. The PD says it puts out 13.6v, but ISTR there is a trick to get it to do 14.4? The NOCO is uber-smart, when I put a meter on it it seemed to do a slow cycle between 13.6-13.8v. No doubt it does other stuff when I am not looking. I could make it do 20 or 30 amps if I put clamps on the other outputs.
I also have 24v chargers: A just-arrived ebay Meanwell that can do 28v 10 amps, and a couple 5amp-ers.
Should I charge these guys separately because they might respond differently, or connect them in pairs, series or parallel, so I can give them high amps (PD) or high volts (Meanwell)?
Or should I order that adjustable volts and amps ebay power supply and give them fixed amps?
I want to do right by these batteries after going thru so much to get them! And the new van, but that's another day ;).
