I have had the battery icon come on several times especially in the morning. So since my vehicle has a standard wimpy 65 amp alt. I had it upgraded to 195 amp G3? and for some reason still get the batt icon but just not as often, mostly in the morning. You could be suffering from short trip driving and it's not charging up the system each time or have the basic wimpy factory alternator. I do have 1200, 300 and 50 watt amps drawing off mine the guy that upgraded my alt. said if I needed more than 195 amps then somethings wrong, so I'm going to upgrade my stereo wires to 0/1 gauge, that should do it. Good luck with yours, check your wires.
