I did not ask if the battery is GOOD, I asked how OLD is it?

TESTING these batteries has sometimes proven to be a waste of time, I KNOW it sounds nutty, but if that battery is old, and you are gonna throw PARTS at the problem, a good part to throw at it is a new battery.

I even ran into this iwth my Durango. Damn thing cost me 1 1/2 hours of labor and a TOW BILL. Fooled three mechanics..... then an old guy told 'em to replace the battery. Damn thing started and ran just fine!
