So i've gotten up twice this week to a dead battery, I went to Battery Source (the local battery place) and the guy checks my batt and says it's crapping on me. OK dude give me a battery. So the guy goes and grabs one of those off brand batteries and tries to stick it in and he's fighting the screw bracket to go in and it wont line up. After five minutes of this torture waiting
for him to scratch my car I said dude that battery dont fit right. He flagged his partner out and told him what was up, he walks to the back and returns with a Motorcraft battery. Fits fine. So the other one has a fat lip on the bottom, it may look the same but it's not.
