Im beginning to think the battery in my 2004 GC is the original factory unit. Its got a Chrysler sticker on it, but according to the service history the jeep fell out of the dealer servicing network after the warrenty expired. Franchise Dealers charge so much for a battery that no one with any sense buys from them.
I spoke to an Internet battery dealer who said they had heard of some cars going 10 years on the original battery's. So I figure Im on borrowed time with this one.
Still, 9 years so far, thats good going !!
