I bought the Everstart Maxx H8 yesterday. Received a Walmart gift card for $100 yesterday and the battery only cost $120 so it was a no brainer for me.
I believe the old battery was original unless previous owner replaced it with a Mopar battery. If original it lasted a little over 100,000 miles. Actually it was still cranking just taking a little longer in the morning to start and for some reason this week the service 4wd message was poping up during cold cranks (the real reason I desided to get a new battery since I knew it was related). Oh and good thing I replace it because the battery had a small hole next to the negative terminal.
Anyways the WK starts right up with new battery and no service 4wd message. So far so good. We will see how long this one last.
