What is the part number for those O'Riley AGMs?I just put in the O'Riley brand AGM in my truck. More CCA and reserve than the battery it replaced in a smaller and lighter size. My 80 sees daily use so I'll see how long it lasts. The engine cranks considerably faster with the new battery. I was going to do the deep cycle X2 battery from Batteries + but it was almost $75 more than the O'riley battery.
