Where is the 2019 Jeep Compass auxiliary battery located?

According to the owner’s manual, my 2019 Jeep Compass has two batteries. I’ve never driven a car with two separate batteries—I’m used to just one—so I’m wondering where this second battery is located, and how do I get to it?

The 2019
Jeep Compass
actually features two batteries: the main battery and a second, auxiliary battery that’s part of your vehicle’s electronic start-stop (ESS) system—which keeps your Jeep running smoothly throughout stop-and-go traffic, and can even function as a failsafe in the event of main battery failure.
You’ll find this second battery located just in front of the main battery on the right-hand side of the engine bay. To get to it, just pop your Jeep’s hood and locate the primary battery! You’ll see the auxiliary (second) battery mounted just in front of it.
Regular battery maintenance can go a long way in keeping your Jeep running like new. But before you hit the road, make sure you’re covered with the best
