I'd say 4 years is about average for a Motorcraft battery. They don't seem as good as the OEM batteries from GM and Chrysler from my experience.
I guess technically, this is the first official failure that my Explorer has had since I've owned it too!
I'm sure this unbelieveably cold long winter hasn't helped it any either...The past couple months it's been cranking a little slower than I'd like, but it always starts. The little hydrometer eye has been dark for at least two months too.
What really got me thinking it was time for a new one was when I'd have the lights and rear defroster on, the voltage would drop at idle, telling me that the battery wasn't keeping up with demand, and the alternator was having a hard time keeping it fully charged.
This morning, it was really slow getting cranked up, so I put in a new Interstate Mega-Tron Plus MTP-65 battery rated at 1000 CCA. Much more better now! Interstate is the only company that makes batteries as far as I'm concerned...It's all we use at the dealership, and we rarely have warranty issues or failures with them. I'd avoid an Exide (NAPA, DieHard) or GNB battery (EverStart, Champion, et al) like the plague. We see more of those brands fail than all the others combined.
(Our stock car is #18 too!)
So just for the sake of arguement, how many years have you gotten out of your original Motorcraft battery?
