Interesting..... I replaced my 2001 F530 diesel's original M'craft batteries... that lasted 11 years..... with some more. The truck sits a lot but the batteries still charge and start that big diesel well. I'm sold.
...and those are the EXACT batteries I am talking about. They are a group 65. The Dodges use them in the Cummins trucks, too. Almost without fail, when I show a customer the warranty, they pay the extra cost for the Motorcraft. I plan on putting on in my truck, but the battery I have is still chuggin right along.
