interstate batteries sells them also... thats where I got mine, for like $130....

one year warrenty :thumbup:

I had a problem with a ground loop in my car.... The stock battery would die after about 6 hours.... finally, after a bunch of jump-starts, the battery went to shit, so I went and got an optima yellow top.... with the ground loop still there, the optima would drain in 18 hours. thats what I call improvement....

btw, I fixed the ground loop h:
