Today I was listening to music in my TL for about 30 - 45 mins with the engine off. While I was listening suddenly the radio went off and came back on - and suddenly the ABS, VSA lights came on. I tried to start the car and it wouldn't crank. The radio, HFL and central locking were working fine all the time however when I turned the ignition to the on position the radio display would go blank and the ABS, VSA error indicators would come on. Also, my seat memory seemed to have been wiped off. I called the Acura on road service, and the guy jump started the car and it started on the first try.I immediately drove it to the nearest dealer to test the battery, the battery was rated "good" 550 CCA. I am trying to figure out what could have caused it?
1. Did the battery drain out? can 30-45 mins of radio without engine running drain the batter? I have done so in the past without any negative effect on the battery.
2. I left the car in the on position so that the blower is on, could this have drained it?
3. The temperature selected was 70 not auto (ambient temp must have been 65) without the engine running there is no chance the heater came on and remained on, right?

Has anyone been in a similar situation? I just want to be sure there is nothing else wrong with the car.

Thanks!

sounds like u drained the battery 30 to 45 mins with the car key in the on position could do it, plus acura factory batteries suck

I hate cars

You ran the battery dead.

Key on vs accessory powers up all systems that are on when the engine is on. Just sitting there, everything is live.

The heater is just hot engine coolant through a radiator, not a heating element. Worst case is the fan was running.

I'm surprised it lasted 30 minutes before it went dead. Nothing wrong with the car, this is completely normal given the circumstances.

Thanks guys, I feel better that the source of error was me :P ... will be more careful now
I was very happy with the on road service though - first time I used it.
