I shut my car off. Go away and sometime later (I found the radio on when I went in to shop and when I was home so I don't know exactly when it starts up) and my radio starts up sometime after the car has been shut off. I seems this would be bad for my battery. My battery did have corrosion and I cleaned it off - could this be causing it?
