    ODYSSEY Extreme Series Battery PC1220 for 2012-Up Jeep JK Wranglers

    In 2012, Chrysler decided to switch out the standard Group 34 battery they had been using since 2007 and replaced it with a Group 91. For the most part, this would be no big deal as they are pretty much the same thing but, there is one key difference that makes it difficult to use a Group 34 and, that is the terminals are on opposite sides. Because the power and ground leads are cut to such an exact length, you can't simply cross them over and call it a day. Of course, to complicate things even more, a Group 91 battery isn’t really a common size and certainly not one you can find easily in a deep cycle format or, at least not until now.

    As luck would have it, Odyssey offers an Extreme Series Battery PC1220 which is offered in a Group 48 size (a Group 91 equivalent) is really the best battery you can get bar none. In this write-up, you get to see just how east it is to install one in your 2012 or newer JK.

    UPDATE: this article was written back in 2012 and the PC1200 is no longer sold in the US. I would now recommend the 34R-PC1500 which is also a better battery.



    What you will need:
    ODYSSEY 34R-PC1500
    • 10mm Socket/Wrench
    • Long Ratchet Extension
    • Ratchet

    Installation
    Here's a shot of what the new Odyssey Extreme Series Battery PC1220 looks like.


    1. Using a 10mm socket or wrench, loosen the clamp nut from the negative terminal of your battery and then disconnect it. Repeat on the positive terminal.


    2. Use a 10mm socket attached to a long extension to remove the bolt and clamp securing the base of your battery to its tray.


    3. Remove the old battery and replace it with your new Odyssey Extreme Series one.


    4. Reinstall the battery base clamp and secure it in place with the factory bolt. You will need a 10mm socket attached to a long extension for this job.


    5. Reconnect the positive and then negative leads to your new battery and then, tighten up the terminal clamp nuts to secure them in place.


    That's it, you now have a great deep cycle battery perfect for winching and running auxillary lights or even a refridgerator.

    Great write up! Just an FYI, DO NOT drop the terminal bolts into the battery tray because they are a royal pain to get back out. lol Been there done that. One found the smallest hole is the tightest spot and decided to hang out there.

    The Sears Platinum Die Hard Batteries are essential Odyssey's but, they are not available in a Group 48.

    If you got what I had got, it was a Sears Platinum DieHard Group 35. It works but, it's a bit smaller than a 91 or 48.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
