But why is it I constantly see and hear Odyssey and repackaged ones(die hard platinum) being recommended more/higher? Quality, in relation to specs, my friend. I've already found out what I needed about the red and yellow though, lol.
+1 (not an EE, though)
Why would Chrysler use a crummy battery when it would lead to warranty claims and/or poor reliability reports? They test the hell out of Wranglers and decided the newer battery was the best idea based on a cost/benefit analysis.
Perhaps the Pentastar doesn't require the CCAs of the 3.8? Perhaps it had to do with packaging under the hood? Perhaps it had to do with wanting to give the battery a bit of space in the box so it wouldn't get too hot?
I'm not an auto designer or engineer but I can think of many reasons Jeep would want to switch batteries.
