    Review & Install Video

    Specs. If you have installed a dual battery tray, the relay kit by Rugged Ridge is the best way to set up both of your batteries in the most effective way. Accessories like off-road lights, winches, and air compressors put a large strain on your vehicle's battery and alternator. Adding a second battery allows you to supply more power to them and in the event that your primary battery dies, you can switch on the secondary battery and use it to start your Jeep.

    Construction. The design of the switch and the relay gives you three different modes and includes all the parts and hardware you need to install this system. The first position on the switch is the factory single battery mode, the second position will charge both batteries but will only draw from the primary. The third position will allow for both batteries to be used at once, this mode should primarily be used in the event of a dead primary battery or while winching.

    Application. This Rugged Ridge Dual Battery Relay Kit is designed to be used on all 1987-2018 Jeep Wranglers, included YJ, TJ, JK and JL models.

    So this product will not work on newer JK's? 2012-2016?

    • Hello, the Rugged Ridge Dual Battery Relay Kit (87-11 Wrangler YJ, TJ & JK) will work up to 2016 JK's, we are in the process of updating the description.

    Do I have to buy a battery tray separately or is one provided?

    KevinG

    • The Rugged Ridge Dual Battery Relay Kit is only the wires and relay, it will not include a battery tray since the tray would vary based on your Jeep.

    is there a dual battery mount and relay kit available for a 7017 JK unlimited rubicon hard rock yet?? Thanks..

    Robin

    • While we do not carry a kit that includes the relay kit, and tray together, the Rugged Ridge Dual Battery Relay Kit can be used in conjunction with the Rugged Ridge Dual Battery Tray or M.O.R.E. Dual Battery Tray to make a complete kit. Both products are linked below, and will work on a 2017 Hard Rock Rubicon. https://www.extremeterrain.com/rugged-ridge-dual-battery-tray-1217.html https://www.extremeterrain.com/more-dual-battery-tray-jk-jkdbt12.html

      If you have a 2012 JK, avoid this kit

      I purchased this kit (along with the dual battery tray from Rugged Ridge) and there is no pre-established mount for the relay solenoid on the tray as it is advertised. I had to fabricate my own mount (pain) which defeats the purpose of purchasing an in-tandem relay kit and tray. The other good reviews on here have come from 2011 or older Wrangler owners who have a different mounting scheme. I spoke to Rugged Ridge directly and they, too, could not figure out how the solenoid should mount to their own dual battery tray. Avoid this product unless you have the ability to fabricate your own workarounds.

      Great product

      Pretty straight forward if you know your electrical flow. Just got my red and yellow top optima batteries dropped in and the relay kit just allows you to have different capabilities with your batteries. I can know trust that my car won't die when I have my lights, winch, music all going while the cars off and have worries. Little bit of a price, but awesome to have.

      Clear instructions

      It was easy for an amateur like me to read the instructions and hook it up myself. Saved me more than once when I'm out in the woods.

      Great complimentary to the RR Battery Tray!

      I bought this kit when I bought the Rugged Ridge Dual Battery Tray from Extreme Terrain and it was easy to install, bolted straight to the battery tray, and came with clear, concise instructions! So glad I spent the money on this item. I have it hooked to an optima red top (primary) and optima yellow top (auxiliary).
