A 2018 Jeep Renegade uses a standard 12-volt lead-acid car battery. The exact size depends on the engine and trim, but most models take a Group Size 86 (also listed as H6) or 86R, typically delivering about 60–70 amp-hours and roughly 430–540 cold-cranking amps.
To be sure you get the exact battery your Renegade requires, check the battery label on your car or your owner’s manual. The OEM specification can vary by engine configuration and optional equipment.

Choosing the right replacement
To ensure you select the correct battery for your Renegade, follow these steps.
- Check the owner’s manual or the current battery’s label for the exact Group Size (for example, 86 or 86R) and the rated CCA/Ah.
- Inspect the existing battery for terminal layout and polarity to match the replacement.
- Note whether your model uses idle start-stop technology; if so, confirm whether an AGM-style battery is recommended by the manufacturer.
- Compare replacement options from reputable brands, ensuring the replacement meets or exceeds the OEM CCA and Ah ratings and fits the under-hood space.
In short, confirm the group size and electrical ratings from the manual or battery label, and choose a battery that matches or exceeds those specs while fitting your vehicle’s space and terminal configuration.
