last time i washed the car my battery went dead while i was drying it off and jammin to some music, i figured a good battery wouldnt do this, and it has went dead a few times since, i think i left the light on for an hour and its dead, i dont know when it was replaced last, i know its over a year old, sound like a bad battery? I was quoted $160 for a new one, seems high to me :shock:
