So the battery went out on my Jeep. I have two Die Hard platinums in the K5 and so far so good, the last one I bought was $220. I was going to get one for the Jeep, but now they want $250. Holy crap. I see I can get an Optima from Amazon with free shipping for $180 (actually, $150 for top post only). I'm not sure what to do. I take the Jeep into the boonies and it has one battery, so I want it to work. I've heard bad stuff about Optima recently though... any advice? Wasn't there something about Walmart having an AGM?
