I don't get the 'lousy factory battery' thing at all. Motorcraft is the only one I use in my Mustangs (over many decades) and I always get excellent use out of them, with lots of sitting too. Whatever.... .

 

yeah I'm really not sure what is the advantage of the Optima battery ... "regular" ones seem to work fine, as far as I can tell
