I have a pair of Odyssey PC1500s in my Duramax and one Odyssey PC1500 in Dust Off. It is IMO the best battery on the market today. I will also mention that EnerSys, the company that manufacturers the Odyssey, also manufactures the same AGM battery for Sears. So the Sears Die Hard AGM battery is manufactured on the same assembly line as the Odyssey only in a different color case. As everyone knows Sears is always having sales on their batteries so keep an eye out for Sears battery sales and you can save a few bucks. Here are a couple of links to Odyssey battery videos, the second one shows how they are manufactured.
