Most Dodge Charger models use a 12-volt lead-acid battery. The common group size you’ll encounter on many late-model Chargers is Group 94R, though some older generations and certain trims may use Group 75 (or other sizes). Always verify the exact size from your owner's manual or the current battery label for your specific year and trim.
The Charger has spanned multiple generations and configurations, with variations driven by engine options, start-stop systems, and electrical load. This article breaks down typical battery sizes, how to identify the correct one for your car, and tips for replacement and maintenance.
Common battery sizes and what they mean
Group sizes you may encounter
Before listing the sizes, note that Dodge has used several 12-volt battery groups across Charger generations. The most frequently seen ones are Group 94R for many contemporary Chargers, with some older or specialty models using Group 75 or related variants. Start-stop-enabled versions may use AGM batteries, which can have different group numbers but still fit within the same general size range.
- Group 94R: A widely used 12-volt option on many late-model Chargers; typically supports modern electrical loads and start-stop systems, with varying CCA and RC ratings by supplier.
- Group 75 (and related 75/58 variants): Found on some older Chargers or configurations; different dimensions and terminal layouts, so fitment matters.
- Group 94 (non-R version): Some earlier Chargers used the traditional 94 group; terminal orientation and dimensions may differ from 94R.
- AGM-equipped batteries: Trims with start-stop systems may require an AGM battery, which can share a similar external footprint with groups like 94R but differs in internal construction and jump-start characteristics.
Concluding: The exact group size depends on the Charger’s year, trim, and whether start-stop is equipped. Always confirm with the label on your current battery or the vehicle’s manual.
How to confirm the exact battery size for your Charger
Use these steps to determine the precise group size and rating for your vehicle:
- Check the owner's manual or the battery section of your Dodge Charger for the recommended group size and type.
- Inspect the current battery’s label for the group size (for example, 94R, 75, etc.), CCA (cold-cranking amps), RC (reserve capacity), and terminal layout.
- Use your VIN on Dodge’s official site or with a dealership/auto parts retailer to pull the exact spec for your year and trim.
- If replacing with an aftermarket battery, verify compatibility with any start-stop system (AGM vs flooded lead-acid) and ensure the selected size fits in the tray.
- Consider climate and driving habits when selecting CCA and RC to ensure reliable starts in extreme temperatures.
Concluding: The precise battery group size is year- and trim-specific. Always verify via the vehicle’s label or official documentation to avoid fitment or performance issues.
Tips for replacement and maintenance
When choosing a replacement and installing it, keep these considerations in mind:
- Battery type: AGM batteries are common for Chargers with start-stop; if your car doesn’t have start-stop, a conventional flooded lead-acid battery may be acceptable depending on the factory spec.
- Physical fit: Make sure the battery fits the tray, with secure mounting and proper terminal orientation (positive/negative) for your model.
- Electrical compatibility: Ensure the new battery meets or exceeds the original CCA rating and RC to handle cold starts and electrical loads.
- Safety: Disconnect the negative terminal first and reconnect it last; avoid sparks and wear eye protection when handling batteries.
Concluding: Matching the correct group size, type (AGM vs flooded), and electrical ratings is essential for reliable starting and avoiding electrical issues on a Dodge Charger.
Summary
In short, the Dodge Charger typically uses a 12-volt battery, with Group 94R being the most common size for many modern models. However, the exact group size can vary by year, trim, and whether the car uses an start-stop system (which may require an AGM battery). To ensure you get the right battery, check your owner's manual or the current battery label, or consult a dealer/parts retailer with your Vehicle Identification Number (VIN). This will help you select the correct size, rating, and type for your Charger and climate.
