I'm tellin ya, the best thing you can get is a jumper battery...its way easier when the wife or kid or your stupid ***** leaves the door open a crack and a few hours later the battery is dead,,,way easier than moving your other car if you have one to line up for jumper cables ..if you have them...comes with a cig lighter and wall charger, in my miata (battery in back) I just jump it off and drive around for a few miles and both batteries are recharged......you can charge at the field with it and not worry about your car battery
less than $30 at walmart for a black and decker....Rog
