So the next question is whether the battery is fully charged.
It's possible the's a bad/loose plate in the battery, but the clicking sounds like its right there inthe dash.
Charge it up on a charger and see what the charger indicates while doing so.
This was just after a cold start after sitting for a while, and I didn't have the charger on it, so it was probably just charging. I can try putting the battery on the charger.
