Are you saying the regulator has to be changed when switching from a lead acid to an AGM? What is the p/n of a H8 AGM regulator ?
I have a blue top Optima that was around $84 from Costco, that was a long time ago for that price.... my guess 15 to 20 years (today they are around $200). It is still working fine in my 92 VW diesel with the stock alternator/ regulator.
