The 2020 Jeep Cherokee is a popular midsize SUV, loved for its versatility and off-road skills. For drivers who want reliability, understanding how many batteries it has—and what types—is important.
Whether you’re new to cars or have some experience, knowing about your Cherokee’s battery setup helps you avoid surprises, especially in emergencies or when planning maintenance.
Let’s break down exactly how many batteries the 2020 Jeep Cherokee uses, why, and what that means for you.
How Many Batteries Does A 2020 Jeep Cherokee Have?
Most 2020 Jeep Cherokees have one main battery under the hood. However, some models include a second auxiliary battery if they feature the engine start-stop system. Here’s how to know which setup your SUV has:
- Standard models (without start-stop): 1 battery
- Models with engine start-stop: 2 batteries (main + auxiliary)
The main battery powers the engine and most electronics, while the auxiliary battery supports the start-stop system. This extra battery helps the car restart smoothly at stoplights and reduces fuel use.
Main Battery: Location, Type, And Specs
The primary battery is easy to find. It’s under the hood, on the passenger side near the front. All 2020 Jeep Cherokees use a 12-volt lead-acid battery for main power. Common specifications include:
- Group size: 48 (H6)
- Cold Cranking Amps (CCA): 600–730 CCA
- Reserve Capacity: 120 minutes or more
Most owners choose a battery from brands like Mopar, DieHard, or Interstate. Make sure to match group size and CCA when replacing the battery for best performance.
Auxiliary Battery: When And Why It’s Needed
If your Cherokee has engine start-stop, there’s a second, smaller auxiliary battery. This battery is usually hidden, located near the main battery or under the passenger seat in some trim levels. Its purpose is to:
- Keep electronics running when the main engine turns off at stoplights
- Help the main battery by handling the extra load from frequent restarts
Specs for the auxiliary battery:
- Voltage: 12V
- Type: AGM (Absorbent Glass Mat), for better recharge and reliability
Both batteries work together to give you smooth driving and energy savings.
Comparison: Cherokee Trims And Battery Count
Not all Cherokees are the same. Here’s how battery count matches up with trim and features:
| Trim/Feature | Number of Batteries | Start-Stop System |
|---|---|---|
| Latitude, Limited (No Start-Stop) | 1 | No |
| Trailhawk, Overland (With Start-Stop) | 2 | Yes |
If you’re not sure, check your owner’s manual or look under the hood for a second battery. Some dealers can also check using your Vehicle Identification Number (VIN).
Key Signs Your Cherokee Has Two Batteries
Many drivers don’t realize they have two batteries until one fails. Here’s how you can tell:
- Start-stop system: If your SUV shuts off at stoplights and restarts automatically, you have two batteries.
- Multiple battery cables: You’ll see extra wiring near the main battery.
- Dashboard message: Sometimes, a “dual battery” warning appears if there’s a problem.
If you see these signs, be prepared to replace both batteries together for best results.
Changing And Maintaining Cherokee Batteries
Replacing a battery in the 2020 Jeep Cherokee is straightforward if you know the basics. Here are the steps:
- Turn off the car and disconnect the negative battery cable.
- Remove the hold-down bracket and battery cover.
- Lift out the old battery and install the new one, matching the terminals.
- Reattach the hold-down and cables, starting with positive.
If you have an auxiliary battery, it’s best to let a mechanic handle it. Access can be tricky, and both batteries should be tested and replaced together to avoid electrical problems.
Typical Battery Lifespan And Costs
On average, main batteries last 3–5 years in the Cherokee, depending on climate and driving. The auxiliary battery may wear out a bit faster, especially with a lot of stop-start driving. Here’s a quick cost comparison:
| Battery Type | Average Lifespan | Replacement Cost (USD) |
|---|---|---|
| Main Battery | 3–5 years | $120–$250 |
| Auxiliary Battery | 2–4 years | $80–$180 |
Some car owners replace both batteries at the same time for convenience and reliability.
Common Mistakes When Handling Cherokee Batteries
- Ignoring the auxiliary battery: Forgetting about the second battery leads to start-stop failure.
- Wrong battery type: Using a non-AGM battery in start-stop models can shorten battery life.
- Mixing old and new batteries: This can overload the electrical system.
Always double-check your owner’s manual or ask a professional if you’re unsure.
Non-obvious Insights For Cherokee Owners
- Battery drain can happen even when parked. Some electronics (like the alarm or remote start) use power even when off. If your Cherokee sits for weeks, consider a trickle charger.
- Frequent short trips wear out batteries faster. The alternator may not fully recharge batteries on short drives, especially with the start-stop system active.
- Check for recalls. Occasionally, Jeep issues battery-related recalls or service bulletins. Stay updated to catch free repairs or replacements.
Why The Battery Setup Matters
Having the right battery setup ensures your Cherokee runs smoothly and starts every time. It also protects sensitive electronics and keeps features like remote start, navigation, and the sound system working correctly.
If you plan to add aftermarket accessories (like dash cams or subwoofers), check your battery’s capacity first. Overloading the system can shorten battery life and lead to unexpected failures.

Frequently Asked Questions
How Do I Know If My 2020 Jeep Cherokee Has The Start-stop System?
If your engine shuts off automatically at stoplights and restarts when you release the brake, your Cherokee has the start-stop system. You’ll also see a button to disable it near the gear shifter.
Can I Use A Regular Battery Instead Of Agm In My Cherokee?
No, if your Cherokee has start-stop, it requires an AGM battery for the auxiliary slot. Regular batteries can fail quickly due to frequent cycling.
What Happens If One Battery Dies But The Other Is Fine?
If either the main or auxiliary battery fails, the vehicle may not start, or the start-stop feature may stop working. It’s best to test and replace both batteries at the same time for safety.
How Long Does It Take To Replace Both Batteries?
Replacing both batteries can take 30–60 minutes. The auxiliary battery is harder to access, so many drivers let a professional handle it.
Are Battery Replacements Covered Under Warranty?
Most new Cherokees have a 3-year/36,000-mile warranty covering battery defects. However, normal wear is not usually covered. Check your warranty booklet for details.
Understanding your 2020 Jeep Cherokee’s battery setup saves money and keeps you on the road. Pay attention to signs of wear, check both batteries regularly, and always match the right type for your model.
This approach ensures smooth starts and worry-free driving, mile after mile.
