The 2020 Jeep Renegade typically uses a 12-volt lead-acid automotive battery. The exact size depends on the engine and trim; common replacements are in the 60–78 Ah range with about 730–760 cold-cranking amps. Always verify the specific group size on your current battery or in the owner's manual.
Battery sizing for the Renegade: what varies
The battery size for the Renegade is not universal. Jeep assigns group sizes based on electrical load, engine choice, and accessory packages. The 2020 model year offered the Tigershark 2.4L engine and various trim options that influence battery specification, so there isn’t a single fixed size for every vehicle.
Common group sizes you may encounter
In the aftermarket and on dealership replacement parts, you’ll often see two group sizes listed as possibilities for this model: Group 86 (also known as H6) and Group 48R. The numbers refer to the physical size and terminal layout that fit under the hood and connect to the starter and alternator.
- Group 86/H6: About 730–760 CCA, 60–78 Ah capacity, tall case commonly used by mid-size SUVs.
- Group 48R: A compact option with similar CCA and Ah ratings, sometimes used in higher-load trims or where a shorter battery fits.
Note: Battery specs vary by market and supplier; always confirm from the vehicle’s label or manual.
How to identify the exact size for your vehicle
To ensure you buy the correct battery for your specific Renegade, use these steps to confirm the proper group size and specs before replacing.
- Inspect the current battery for a group-size code (for example, "Group 86" or "H6") on a label near the terminals.
- Check the owner’s manual or the vehicle’s official parts catalog for your VIN to obtain the recommended group size and CCA/Ah requirements.
- Contact a Jeep dealership or reputable parts retailer with your VIN to confirm the exact group size and specifications.
- Measure the physical dimensions of the battery bay and the terminal layout if you’re considering an aftermarket option to ensure a proper fit.
Once you have the correct group size, choose a battery that meets or exceeds the original specifications to ensure reliability and warranty coverage.
Maintenance and replacement tips
Maintain your Renegade’s battery by keeping terminals clean and free of corrosion, ensuring a secure connection, and avoiding prolonged exposure to extreme temperatures. If your climate experiences harsh winters or hot summers, consider a battery with higher CCA or Ah ratings to maintain reliable starts. Replace the battery every 3–5 years or sooner if you notice slow starts or electrical dimming, and have the charging system (alternator, belt) checked if problems recur.
Summary
The 2020 Jeep Renegade does not have a single universal battery size; the correct group size typically falls around Group 86/H6 or Group 48R, with capacities around 60–78 Ah and 730–760 CCA, depending on engine and equipment. The best way to ensure an exact match is to check the current battery’s label, consult the owner’s manual or VIN-specific parts catalog, and verify with a dealer or reputable parts supplier. Proper identification helps ensure fitment, performance, and warranty coverage for your Renegade’s electrical system.
