i don't have a bunch of fancy gizmo's but can relate to this. i got stuck in ocean city traffic, basically idling for an hour. i jumped off 50 on to 707 (to get a beer at the 707!) and when i went to leave my battery was dead, killed by my headlight and lightbar. i push started her and have never had a problem since (knock wood) but the "opportunity" is still there. now when i know i'm going to be idling for quite a while i kill the lightbar. ymmv!
