Yes, some Jeep Compass models, particularly those equipped with Start-Stop technology, come with two batteries. These are typically referred to as the main battery and the auxiliary battery (or secondary battery).
Why the Jeep Compass Has Two Batteries
1. Start-Stop System Support
- Vehicles with Start-Stop systems require extra power to restart the engine frequently when stopped at traffic lights or in traffic jams.
- The auxiliary battery helps handle the electrical load during these periods, while the main battery focuses on starting the engine and powering essential systems.
2. Powering Electronics
- Modern vehicles like the Jeep Compass have lots of electronics, including infotainment, safety systems, and climate control.
- The second battery ensures that these systems remain powered reliably, even when the engine isn’t running.
Which Jeep Compass Models Have Two Batteries?
- Models with ESS (Engine Start-Stop) technology, commonly found in 2017 and newer Compass models, often feature a dual battery system.
- Base models without the Start-Stop system may only have one main battery.
Where Are the Batteries Located?
- Main Battery
- Located under the hood, like in most vehicles.
- Auxiliary Battery
- Typically located under the fuse box or near the front driver-side fender, depending on the model year.
Signs You Might Have a Battery Issue
- Start-Stop system not working properly
- Check Engine Light or Battery Light
- Electrical issues (radio, lights, power windows acting up)
- Slow or failed engine starts
FAQs About Jeep Compass Batteries
1. Do all Jeep Compass models have two batteries?
No. Only Start-Stop equipped models typically have two batteries. Non-ESS models generally have one battery.
2. Can you replace just the auxiliary battery?
Yes, but if one battery is weak, it’s often wise to test both batteries and consider replacing them together if needed.
3. How long do the Jeep Compass batteries last?
- Main batteries generally last 3 to 5 years.
- Auxiliary batteries often have a shorter lifespan—around 3 years—because they cycle more frequently.
4. How do I know if my Jeep Compass has ESS (Start-Stop)?
If your vehicle turns the engine off automatically at stoplights and restarts when you release the brake pedal, it has ESS—which typically means it has two batteries.
Final Answer
Yes, many Jeep Compass models, especially those with Start-Stop technology, are equipped with two batteries: a main battery and an auxiliary battery. These batteries work together to support the vehicle’s electrical systems and ESS functions, ensuring reliable performance. Always check your owner’s manual or consult a Jeep service technician for specifics on your model.
