Starts fine if was turned off, engine temp is irrelevant.

Scenario 1 - Last month drove to sydney (3 hrs). Got to a servo in tempe, turned off car normally, got fuel, and started up again, as I went to pull out into the princess hwy, I stalled it. Go to restart, and battery is flat. I had to push start the car.

Scenario 2 - Car is cold (eg sitting overnight), I start it normally. If I stall it while backing out etc, then battery is flat....
