I have a charger, but really to keep a charge on the batteries for long periods of no use.. I have the promariner 20A, 3 bank charger since I'm wanting to add a 3rd battery because of the stereo upgrades

I need a new battery.. My number 2 is trashed.. Won't hold a charge.. Got to look into a good deep cycle...

My comment was based on if he would be playing the stereo all day draining 1 or 2 batteries then using the 3 to start the boat. If he is wired to run on "all" batteries then I would think at start-up charging 2 low batteries could load the alternator pretty good. But I could be wrong???
