Johnson Controls makes most MB batteries. They also make several aftermarket batteries, including Duralast (AutoZone). I just had to replace my battery and I did a LOT of research. Duralast batteries are backed by the best warranty coverage in the industry. 2 years full coverage, 6 years pro-rated replacement. Duralast Gold, 3 years full coverage, 7 years (!!!!) pro-rated. The gold's are sealed, no maintenance. Nobody else touches this. We are talking about nationwide warranty coverage... ANY Autozone will process a warranty claim. You are getting an MB battery without the logo for less money with way better warranty coverage.
