Protect your JL / Gladiator's cranking battery from being drained down by your aftermarket accessories. Fits 2018 and up Jeep Wrangler JL and JT Gladiator truck. Requires 2 identical Group 25 size batteries, sold separately. Here's how it works. When your cranking battery is charged at 13.2 volts for a couple minutes, the smart isolator automatically connects the batteries together and they are charged at the same time. When you park and turn off the engine, but continue to use accessories such as lights or the stereo or a CB, both batteries begin to drain down. When your main cranking battery reaches 12.7 volts, the smart isolator separates the batteries, so that your cranking battery will have enough power to start the engine. The second battery continues to power your accessories for as long as it will last. What if your cranking battery is somehow drained down too low to be able to start the vehicle? We have a solution for that. Press the Start Boost button and the isolator will connect both batteries together for 1 minute, acting like built-in jumper cables to jump start your engine off your accessory battery. As long as the accessory battery has enough power, you'll be able to start your vehicle instead of being stranded with a dead battery! The alternator will charge both batteries for 1 minute, then switches back over to automatic mode to reduce the strain on your alternator.
