Age of Motorcraft batteries


My F-250 (which I bought used) came with Motorcraft "Tested Tough Max" batteries, with the 100-month pro-rated warranty. It looks like there was a barcode on the top of each battery, but that barcode has worn off. The only numbers still somewhat readable on either battery are the model and serial number.

Can the manufacturing date be deciphered from the serial number? I'm trying to find out how old the batteries are. I checked out the Motorcraft website, but I didn't find any info on this subject.

What is the useful life that one can expect from this model of battery? The cranking has been a little weak for the past few days. I cleaned up the battery teminals, and it seems to have improved.

If it should come down to battery replacement, is this "Tested Tough Max" a good battery, or is there something else I should try? Since the pickup is only 5 years old, there is likely still some warranty left on the existing batteries.

Re: Age of Motorcraft batteries

I canít help you identify how old the batteries are. I got 4 years out of my factory batteries. I just replaced them about a month ago. I bought the truck in October 02. Iíd say if those are original batteries then they have lived a long life. I bought my replacements from Napa. I canít remember what brand but they had about 100 more CCA each than my factory ones did.

Re: Age of Motorcraft batteries

I replaced my batteries jan. of this year. My truck is a early 99 (8/98) build date so I got a little over 7 years on the original batteries. So guess what went back in. I have not had a battery last this long over the years so I hope the replacements are as good as the originals.

Re: Age of Motorcraft batteries

First off, if the batteries have the red labeled "Tested Tough" on them, they are not original batteries to the truck. Factory batteries are typically black labeled and do not say "Tested Tough" anywhere on them. Secondly, manufacture date would be found on one of the sides on a small round sticker(about 3/4" dia.). It should have a letter and a number. The letter corresponds to the month and the number to the year manufactured.

Another thing I learned recently from our Warranty Administrator, even if you purchased the truck with batteries and they fall under warranty, unless you have a copy of the receipt that shows exact purchase date, Ford will not warranty the battery. They require a copy of the receipt sent with the warranty claim.

Re: Age of Motorcraft batteries

The OEM batts in mine, a 6/98 build, lasted until 2004, but still had decent life, I replaced them thinking it was the cause to my hard starts, when it was the GPR instead. I replaced them with a pair of Optima reds, because I plan to move them both to the passenger side, otherwise I would have gone with another set of Motorcrafts.
