Protect your 4Runner's cranking battery from being drained down by your aftermarket accessories. Fits 5th gen, 2010 and up Toyota 4Runner. Requires 2 identical Group 25 size batteries, sold separately. Here's how it works. When both your batteries are fully charged at 13.2 volts, they are automatically connected and 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. After you crank the vehicle, your main cranking battery will be charged up to 13.2 volts first, and then the isolator will begin charging your accessory battery. By only charging one battery at a time, your alternator is protected from excessive strain. 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.
