I actually had one go bad on me as well. After taking it to the store I got it from, I talked with the owner while it was getting recharged. Turns out with the technology, some of the cores can get very very minor cracks that get passed over in the pre-sale testing process they do on each battery. Unfortunately, it's just an evil of the technology they use, and is pretty unavoidable. He said that that type of problem IS relatively common, about 1 in 10 get it. Usually shows up 3-6 months after the battery has been used, more quickly in extreme temps. But, on the same note, the ones that don't get it are damn near bulletproof. And if yours does, it can usually be fixed by a good over-charging which will reset it. That seems to have been the exact problem with mine, as it's been absolutely perfect for 3 months since I had it done.
So I'd stay stick with it, try to get it recharged and if it's still shot, have them send it to Optima. They have a killer warranty, IIRC.
