If equipped, the 2015 Jeep Cherokee auxiliary battery location should be found near the main battery, which is found under the front passenger seat. However, it’s not likely a regular Cherokee would have one—it’s more likely that a 2015 Grand Cherokee would have an auxiliary battery.
At any rate, to access your battery, you’ll need to move your Cherokee’s passenger seat forward and up. Then, from behind the vehicle, remove the floor panel under the passenger seat, revealing the battery.
It takes less than a minute to get started, and the average driver who makes a switch saves over $800 per year on car insurance!
