Sears Platinum is made by Odyssey. It's AGM and deep cycle (like a golf cart or fork lift battery), which means it can be repeatedly discharged and charged without any sulfating issues. And, it's dry cell, so no liquid acid. Sears is probably a little cheaper than Odyssey and has a 4 yr warranty vs. 3 yr for the Odyssey. Exact same battery though, except for labeling.
