If you’ll be working with any components related to your vehicle’s electrical system, disconnecting your main and auxiliary batteries is necessary for safety reasons. The 2019 Jeep Wrangler auxiliary battery location is found under your vehicle hood, but it’s not immediately visible.
It can prove a little difficult to access. If you were facing your hood, the 2019 Jeep Wrangler auxiliary battery location would be located behind the main battery in the upper left corner of the hood area. Several layers of panels need to be removed before the battery is visible.
If you’re not comfortable or able to access the battery, you can always have a certified mechanic service your vehicle.
