Was wondering if there are any warning signs that a battery will go soon. Anytime I need to go out (kid drop off or pick up) I don't have a 2nd car available to jump-start it.

Yeah, I've been asking the same questions. My low battery signal comes on when I've been coding so I was wondering if it was time for replacement. I've also seen it occasionally when I've been washing car etc. I bought a battery tester, as recommended, and it checked out just fine.

My problem may be that I'm not driving the X5 enough...
