I just bought two of these batteries for my 06 F250 because I got an engine code that stated the injector voltage was low. After some research I was lead to check the batteries first and so I did. O'reilys said one of my batteries read low voltage after cranking so I replaced them both. After driving 15 miles the check engine light came back on. I checked my old batteries with my on multimeter and they were holding a charge fine. After more research I found out that the issue is with my FICM and not my batteries at all. Anyways, now I have to BRAND NEW batteries with nothing to do with them.

The batteries were purchased for on 6-4-11 for $129.00 a piece and after core charges and taxes the total for both was $313.41. They come with a 3 yr replacement warranty plus a 100 month pro-rated warranty (they will give you a discount for the purchase of a new battery) which is transferable as long as you have the receipt. I'm asking for $250 which means I'm already taking a decent hit. Plus since I paid for the core charges you can return you old batteries to O'reilys and they will give you money back (probably $25 or so).That brings your savings close to $100.

 

Do you still have these batteries?
