Great choice that is what I got the Die Hard Platinum for installed. Well worth it and the warranty that comes with it.

Deep cycle isn't the attribute to look for, although some batteries are good for starting AND deep cycle. But they're a compromise. The Die Hard name is applied to many Sears batteries, but (IIRC) only the Platinum uses the AGM (absorbed glass mat) technology to make it unspillable. Unspillable is a nice feature to have, and that technology (flat plate + AGM) is shared by the Odyssey high end batteries.

What the Optimas and Exide ORBITAL have is spiral-wound AGM plates, which wastes a bit of the battery volume, giving you fewer amp-hours capacity, BUT the huge advantage (to me at least) is the vibration resistance of the spiral wound ones. I had a friend in an old Suburban have his flat plate battery short out internally (!) on a Death Valley washboard. Almost lost the car in the ensuing battery meltdown. So I'm not changing from my choice of spiral-wound, although the recent reliability horrors of Optimas is going to make me lean toward an Orbital when I need a new one in the next 6-12 months. My current Optima was from the previous factory, and has been essentially worry free for 60K hard-bashing miles.

I didn't see it on a quick search. When to run to get fast food and the battery was dead when I went to leave again.

I think it's quickly becoming the off-roading standard.
