Yesterday the truck would not start in the mall parking lot ---Slow cranking ----Battery was bad!----The battery from the factory says 750 Amp. I went to sears Auto center on the other side of the parking lot and looked over the batteries. No 750 Amp ones...Does it matter if the amp rating is the same ? Are there minumim or maximum amp ratings required for the truck? ---Batteries are freaking heavy to carry any type of distance ---then To have to go buy tools to remove the battery damn , I should be more prepared -----But I got it fixed.
