I was able to stop by CanTire yesterday. The clerk at the counter didn't seem to believe me that a battery could self-discharge overnight. He tried to convince me that lead-acid batteries self discharge quickly overnight when they are disconnected from the car (what!?).
Anyways he reluctantly put the battery on the test machine and it came back as 'bad'.
So here I am with a replacement battery... fully charged I read 12.8V off the terminals. With the engine running (cold), about -10 Celcius outside, the voltage goes up to 14.75V. I also tried reving the engine, the voltage was rock solid between 800rpm to 4,000rpm.
Hopefully I'll be ok... of course due to work again, I have not tried to start it for the last 24hrs...
