12 years and 4 months and 59,634 miles of service.

Having read all the threads on batteries here (thanks to all for the help!), I noticed that most have to replace batteries every 3-5 years, even saw some OEM that died before 30k miles. Talking with Greg Pylant, we wondered if anyone had one that survived longer? Don't think I can salvage her as she is to unreliable, and my XF is my only means of transportation. Thinking of getting the Super Start Extreme model at O'Reilly's. Thoughts?

Got mine at WalMart, their Everstart MAXX, on sale total under $105 and some pennies with the tax and core (I brought a tractor battery back for the core), I installed it.
When you buy/install it, open the hood straight up (helps remove old/install new). While your in there, clean up any debris/acid accordingly and MAKE SURE you clean both terminals AND the clamps. If your inclined (most suggest this step) check the other ends of the cables where they attach for loose or corrosion laden contact points (grounds for the NEG and terminals for the POS)
BEFORE you install the new battery! One final note, remove the NEG first, then POS terminals. THEN connect the POS on the new battery then the NEG. Have fun!
