I would recommend trying to get all of your batteries in the future all the same type, as the Prosport20 Charger (if you are getting one in the future) are designed to charge batteries of same type (Flooded(lead-acid)/STD AGM, GEL & High Performance(HP) AGM) if that makes sense, I'm not talking about "groups" as types... but what do I know, lol

It sounds like you are, but I just wanted to throw that out there.
