What kind of battery does a Challenger take?
The Dodge Challenger uses a 12-volt automotive battery. The exact size and type vary by model year and trim, so check the owner's manual or the current battery label for the precise Group Size and rating for your car.
Battery Type and Voltage
All Dodge Challengers operate on a 12-volt system. The battery provides starting power and supports the electronics; while base models use a standard flooded lead-acid battery, some high-performance variants or modern configurations may use an AGM (Absorbent Glass Mat) battery to support higher electrical demands.
Important Considerations Before Replacement
Before choosing a replacement, consider the following factors:
- Group size (the physical dimensions and terminal layout) must match the vehicle's tray and cables.
- CCA (cold-cranking amps) rating should meet or exceed the OEM spec to start reliably in cold weather.
- Battery type (flooded lead-acid vs AGM) depends on vehicle features like start-stop and high electrical demand.
- Warranty terms and battery life expectations for your trim and climate.
- Terminal orientation and polarity (positive/negative) must match the existing setup.
In short, the right battery depends on year, trim, and climate; verify the exact specification before purchasing.
How to Find the Exact Battery for Your Challenger
To nail down the correct battery for your Challenger, use these steps:
- Consult the owner's manual for the recommended Group Size, CCA, and reserve capacity.
- Inspect the current battery label for Group Size and rating; note the terminal arrangement.
- Use your VIN when shopping at parts stores or with a dealer to get the precise OEM specification.
- Ask about AGM vs flooded variants if your Challenger has start-stop or high electrical draw.
- Choose a battery with a warranty that suits your driving climate and usage.
With the right checks, you’ll ensure reliable starts and proper electrical performance across seasons.
Maintenance and Replacement Tips
Tips for longevity and safe replacement:
- Disconnect negative cable first; reconnect it last when removing or installing a battery.
- Clean corrosion from terminals and ensure clamps are tight.
- Dispose of old battery at a proper recycling facility or have the auto shop handle it.
- If your Challenger has start-stop, ensure you use an AGM battery that supports frequent cycling.
These practices help prevent charging issues and extend battery life.
Summary
The Dodge Challenger relies on a 12-volt automotive battery, but the exact Group Size and type depend on the model year, trim, and features such as start-stop. Always verify specifications through the owner's manual, the existing battery label, or a dealer to ensure you select the correct replacement. When in doubt, consult a qualified technician to confirm the right choice for your specific Challenger.
