Typically, no: the 2017 Grand Cherokee uses one 12-volt battery located in the engine bay, and a second factory-installed battery is not standard on most trims.
The full context: This model year does not employ a 48-volt mild-hybrid system, and the electrical system is designed around a single primary battery with start-stop features handled by that battery on applicable trims. If you see two batteries, it could be due to a nonstandard configuration, aftermarket modification, or a regional variation. The sections below outline typical layout and how to verify your specific vehicle.
Typical battery layout in a 2017 Grand Cherokee
Before listing what you are likely to find on most 2017 Grand Cherokees, note the following:
- One 12-volt lead‑acid battery located in the engine compartment (primary battery).
- No factory dual-battery system in standard US-spec trims for this year.
- Start‑stop tech, where equipped, draws from the primary 12‑V battery or uses its own system management, but does not imply a second battery under normal configurations.
- The vehicle does not use a 48‑volt mild‑hybrid system as part of the stock drivetrain for most 2017 models.
In practice, this means that most 2017 Grand Cherokees you encounter will have a single battery, unless a nonstandard setup has been added later by an owner, dealer, or regional spec.
Where to look and how to confirm
Inspecting your specific vehicle and checking documentation helps verify the battery setup:
- Look under the hood for a single 12‑V battery. It is typically in the engine bay, but placement can vary slightly by engine and trim.
- Check the owner's manual or a factory service manual for the battery section and any mention of a second/auxiliary battery.
- Inspect the rear cargo area and wheel wells for an additional battery or separate battery box, which would indicate a non-standard configuration.
- Verify the VIN with a dealer or by using the vehicle's built‑in number to confirm factory equipment and any regional variations.
- If you suspect a second battery, consult a professional to identify whether it is aftermarket or part of a regional spec, and ensure proper disconnect/re-connect procedure is followed when servicing.
In short, check your specific vehicle to be certain, but the default expectation for a 2017 Grand Cherokee is a single battery.
Summary
Bottom line: For the 2017 Jeep Grand Cherokee, a factory two-battery setup is not standard. Most versions rely on one 12V battery in the engine bay, with start-stop managed by that system. If two batteries are present, they are most likely the result of aftermarket installation or a non-U.S. variation. Always verify with your owner's manual and dealer records for your exact vehicle.
