Greetings all!
I just purchased 3 new AGM batteries to replace FLA ones. I've got a Xantrex TC4012 charger. I've put the charger in AGM mode. My charger also has two different charging modes:
1. Three-Stage (Bulk, Absorption and Float)
2. Two-Stage (Bulk and Absorption)
I seem to remember reading somewhere that AGM's can be over-charged, but the interwebs shows conflicting information, and Nigel's boat bible is at the marina in the boat.
Any reason to put the charger in two-stage?
Also, my engines are 2005 Mercruiser 5.0MPI's. Should I be looking into alternator regulators...as in are the ones on the engines intelligent enough to charge AGM's responsibly? Or do I need to look into something like an ACR or some other device?
Thanks for your comments!
