Here's yet another option on batteries. Odyssey makes incredible batteries, but they are very expensive. Sears Diehard Platinum batteries are made by Odyssey. I called Odyssey to verify since all I could find online was speculation and rumor (specs match). Anyhow, I put one in my Wrangler and have never had a problem with leaving the stereo on for lengthy periods or heavy winch usage. I have always used Optima batteries in the past, but Odyssey had a big following in the Jeep community, so I gave them a shot. The DHP is not what I would consider inexpensive, but compared to its Odyssey branded counterpart, it's a bargain. Again, just another option. Good luck!
