Had the battery light come on the other day while pulling away from a light. It went out after about 3 seconds or so. But what I also noticed lately is the car is making a "whine" sound when I accelerate. I't not related to the stereo, I checked all that already,

I'm thinking the bearings in my alternatertor have gone for a crap.

Is this possible?

Could be. Have you checked the tension on your belt yet? You have to isolate the source if the whine. Could be a tensioner, could be brushes. Bad bearings in the alternator usually won't cause a dip in output voltage to make your light come on, unless it was seized or seizing. It would just make noise.
