I don't know where the battery is on your Ford but on my Fords it is the only battery that will fit unless a whole new battery box was fabricated and mounted in a more accessible location. My 4DLT batteries are under the floor in the cab. The battery can be changed in the 9600 with Allen cab from the exterior. Have to put the battery down through the floor from inside on the 8600 with the Hiniker cab. The 9600 battery is a bit easier to service and change but both are a real pain and I cuss the guy who thought this up! Like Paul says you need a lot of cranking amps for winter. A regular car battery would probably work in warm weather but would it fit? As far as battery brands I tend to think Interstate lasts better than most. I've had 4DLT batteries in CaseIH, NH, NAPA, Exide, and Durastart flavors. None of them lasted over 3 years. I have Interstate 4DLTs in my X600 tractors right now and a pair of Interstate 2XHD 6 volts hooked as 12V in one of my Majors. Put all of them in last fall about the same time. Got a pair of Durastart 6 volts in the other Major and they have done well but I think they are on their last legs now. I'll probably replace them with Interstates when the time comes, mainly because no one seems to stock them anymore and they usually have to be ordered. Everybody and his dog is an Interstate dealer and the truck comes through every week.
