A second battery gives your Jeep backup starting power and extra capacity for winches, fridges and lights. Wrangler JL, JK and TJ and Gladiator JT owners add a dual battery tray or complete kit when the electrical load outgrows the factory setup.
This category includes Genesis Offroad Gen 3 dual battery kits, dual battery trays from M.O.R.E. and Nemesis Industries, and replacement battery trays from Motobilt and Mopar. Complete kits typically add the tray, isolator and wiring, while trays alone need your own electrical parts, so read the product details. Trays are sized for specific battery groups, so confirm your battery before ordering.
Shop battery trays from Genesis Offroad, Motobilt, M.O.R.E., Mopar and Nemesis Industries. Finish the setup with battery accessories or power an air compressor. Enter your Jeep in the vehicle selector to narrow the results to parts that fit your model and year.
