So guess what? Yes, today it simply wouldn't start. The engine would try to turn over, but I would only get the starter. And they'd be weak revolutions at that. It just didn't have enough rotation to start up.
I went back upstairs and got a co-worker to help me jump-start it. Then made my way to a nearby Craven Tire & Auto (pretty good place, btw) and got it all diagnosed.
Stock Subaru Impreza battery: 550 CCA (cold crank amps)
My battery: 152 CCA
The starter was good and the alternator was good.
So, $125.00 later, I now have a new battery and a working car.
End of my commute home.
