I read this post a couple days ago and though to myself my car was cranking slowly. So I took a look and saw the black glassmat battery. I though I had the cheaper battery, wishful thinking I guess. Dealer list $293. Plus coding 1 hour labor. Luckily i know the parts guy and he'll do employee pricing for me. $220. and half hour labor to code. Not going to chance it with anything but an oe battery.
