Does a 2020 Jeep Cherokee Trailhawk have two batteries?

Typically no. A 2020 Jeep Cherokee Trailhawk normally uses a single 12‑volt starting battery. Some configurations that include Jeep’s 48‑volt eTorque mild-hybrid system may carry a second energy storage unit, but that setup is not standard on every Trailhawk.


Understanding the battery setups you might encounter


Across the Cherokee lineup, battery arrangements vary by engine and drivetrain option. The majority of Trailhawk models use a conventional 12‑volt battery for starting and electricals. In certain engines equipped with the 48‑volt eTorque mild-hybrid system, a separate 48‑volt battery pack supplements the system, effectively creating two energy-storage components in the vehicle. Whether your specific Trailhawk has two batteries depends on the engine option and transmission configuration chosen for that model year.



  • Standard configuration on most Trailhawk models: a single 12‑volt starting battery.

  • Optional or alternate configuration on eTorque-equipped engines: a separate 48‑volt battery pack to support mild-hybrid functions.

  • The presence of two batteries is not guaranteed and hinges on whether the vehicle is equipped with the 48‑volt eTorque system for that engine option.


Bottom line: most Trailhawk examples use one 12‑volt battery, but certain eTorque-equipped trims add a second 48‑volt battery. If you’re shopping for a two‑battery setup, confirm the specific engine and whether the eTorque system is included.


How to verify whether your Trailhawk has the 48V system


To determine if a given 2020 Cherokee Trailhawk has two batteries, use these checks.



  • Review the vehicle’s window sticker or original Monroney label for mentions of “eTorque” or a 48‑volt system.

  • Inspect the engine bay for markings or components associated with a 48‑V mild-hybrid system, which would accompany a separate battery pack.

  • Consult the owner’s manual or the Vehicle Identification/Specification sheet to see if the 48V eTorque option is listed for that model.

  • Ask the dealer or a qualified technician to confirm whether two energy-storage systems are installed on the specific vehicle you’re considering.


If you don’t find any reference to a 48‑volt system and there’s only one battery under the hood, your Trailhawk uses a single 12‑volt battery. The 48V setup would indicate the presence of a second energy-storage component beyond the standard battery.


Maintenance considerations


When two energy-storage systems are present, maintenance and charging considerations differ somewhat from a single‑battery setup. Follow these practices to keep both systems healthy:



  • Have both batteries tested during regular service intervals, especially if you hear unusual electrical symptoms or notice weak starting performance.

  • Use chargers compatible with each system if you perform DIY charging or battery conditioning; the 12‑V and 48‑V systems require appropriate equipment.

  • Follow manufacturer guidance for jump-start procedures, as improper handling can affect the mild-hybrid components.


Always rely on the vehicle’s manual and certified technicians for specifics about your exact configuration.


Summary


In short, a 2020 Jeep Cherokee Trailhawk generally uses a single 12‑volt starting battery. A second battery appears only if the vehicle is equipped with the 48‑volt eTorque mild-hybrid system on the specific engine option. To know for sure, check the window sticker, owner’s manual, or consult the dealer for your exact VIN and build.

How do I know if my Jeep has two batteries?


Not every vehicle has a dual-battery setup, so how can you be sure? Check the Fitment Finder: The easiest method is to enter your vehicle's year, make, and model into the Batteries Plus Fitment Finder. If an auxiliary battery is listed as a replacement part, your car likely has one.



Where is the second battery in a 2020 Jeep Cherokee?


Before disconnecting power. So just 10 mm to remove those terminals like I said the front one was already loose. And then um excuse me 13 mm to remove the nuts on the auxiliary.



How many batteries are in a 2020 Jeep Cherokee?


Your vehicle is equipped with 2 types of batteries: Auxiliary (for start/stop and other systems) and Primary (for starting).



What happens if the auxiliary battery dies?


It's unlikely that you'll notice any drivability problems with your vehicle once the auxiliary battery fails. The worst thing that could happen is that you won't be able to use the electrical components that get voltage from the auxiliary battery.
