Auxiliary Battery Install

Using the battery platform on the right fender of our 2010 Toyota FJ Cruiser made the installation of the second battery very easy. To make room for the battery I first had to relocate the power steering reservoir. I then used a few sheets of polyurethane under the battery to help secure it in place.

I used the j-bolts and clamp from the primary battery as the hold down.

The auxiliary battery is an Odyssey which provides a very robust durable battery.



Tomas has lived in Colorado since age 5. Having grown up on the Western Slope of Colorado lots of time was spent in the Desert Southwest. Tomas' father introduced him to the love of 4 wheeling at an early age in the high mountains around Aspen, Colorado. While an avid Mountain Biker, Tomas and his Family enjoy adventures in the mountains and desert in the remote locations that can only be reached by 4wd. Day hikes are always a must when on the family trips. While enjoying outdoor activities he wants to share his love as a certified 4wd trainer and ski instructor. Tomas also enjoys caving and cave exploration. Tomas currently resides in Colorado Springs.

    I like what your doing with your new FJ I own a 2007 which I purchased brand new I finally have started a long list of upgrades. I like Odyssey but don’t have a supplier near me even Batteries Plus in my area say they can’t do special orders so my question is is there a comparable battery in the Optima line ? Once again I like what your doing with the new FJ.

      The Sears Platinum is made by Odyssey.

        I purchased the Sears Platinum and have been very pleased with it’s performance. It is less expensive than the Odyssey label.
