In my boat I have an Centaur 12/20 to keep my two batteries fit and ready.
My battery for engine start is a normal lead acid (60ah), and my battery for consumption is a brand new AGM (95ah).
I have a battery monitor (NASA Clipper BM2) to monitor my AGM battery and it seems like it never get charged 100 %, more like 90-94%.
I know, that the charger has different jumper settings for the right kind of battery.
After talking to the dealer about my setup, I was advised to leave the jumpers in the lead/acid mode - is that the root to my problem?
Would it be better to set the jumpers for AGM, or wouldn’t that leave my startbattery with a too low charge voltage ??
Or is the only solution to by an AGM battery for engine start as well?
Thanks for advice
