I have not seen anything here on the new Sears Die Hard Platinum batteries, so I thought I would post this up. Might be another alternative that could work for people. The battery is an AGM type (like the Exide Orbitals and the Optimas) but does not use the spiral setup. The lead plates are straight, and fill the entire box. They are heavy. They have 2 group sizes: 35 which has the proper terminal orientation, and 34 which has the incorrect orientation but much higher reserve capacity. If there is a 34 with reversed terminals no one at Sears seems to know about it. Maybe in the future.
The 35 seems equivalent to an Optima D35, with 740 CCA and 100 RC (versus the Optima Yellow Top D35 with 650 CCA and 98 RC). The only thing I can't tell is the Amps/Hour rating on the Die Hard. They are not cheap at $180, but the Optimas are up that high now too. The warranty is 4 years full replacement.
I've only had mine a couple of days now, but it seems to work so far. I was a bit reluctant to get something with less RC than the stock battery (which lists 113 mins.) but mine had bad corrosion around the positive terminal, and I could not find an Optima or Exide locally with the correct terminal orientation.
