I have the Bosch batteries at the 1000/850 amp rating. If I have to replace them I will go with the Motorcraft 850 amp batteries myself. I havent seen them on sale at $110 yet but I have seen the 750 amps for that price. Maybe you can catch them on sale or something as stated. I did buy a new pair of MC batteries last month when I thought my Boschs were going out but I carried them back 2 days later as my batteries were not my problem.
BTW, the MC batteries will not let the battery cover go on on the driver's side unless you unclip the handle from the battery. Store the handle somewhere for future use as the batteries are heavy and awkward to get in and out of the truck.
