4D battery question/Which one?
Hello everyone. I have a beautiful 2003, 7.3l SMB with only 59,000 miles, that unbelievably, still has the oringal big battery, 4D house battery. While it still works fine, I am getting concerned about its age and am thinking about preventatively replacing it. The Lifeline battery is very pricey, but having lasted as long as it has, it may be worth it. NAPA makes a 4D which is significantly cheaper, so doe Interstate. Which battery have people used with good success? Is the Lifeline worth the extra expense? Any input would be appreciated. Cheers all! Fernando Rivero
