I was thinking this battery thing... may be like the
Kramer Road Test thingy. (Seinfeld) Will we run out of gas...?? I found the video on You Tube..BUT it left out the hilarious "Punch Line" ...where the car finally ran out of gas..somewhere in NY... and Kramer got out of the car and hailed a cab..leaving the car salesman stuck with the car.

PS: I left the flashlight ON All Night (10 Hours) on my bed table. It was still ON at 6:30 AM....I turned it OFF at dawn. . NB
