What kind of battery is in a Dodge Charger?
Most Dodge Chargers use a 12-volt automotive battery. In practice, you’ll typically find either a conventional flooded lead-acid unit or an Absorbent Glass Mat (AGM) battery—depending on the model year, trim, and whether the car uses start-stop technology.
Battery types used in the Dodge Charger
To understand what powers the car from the starter motor to the infotainment system, it's useful to note that the Charger relies on a 12-volt battery, with the exact chemistry varying by features and generation.
Two common configurations
- Conventional flooded 12-volt lead-acid battery
- Absorbent Glass Mat (AGM) 12-volt battery for models with stop-start and higher electrical demand
In practical terms, most Chargers without stop-start run a standard flooded battery, while higher-demand or start-stop-equipped variants favor AGM technology for better durability and cycling resilience.
How to verify the battery type on your Charger
Knowing your exact battery type helps with replacement parts and charging needs. The following checks apply across model years.
What to look for
- Read the battery label for "AGM" or "Flooded" and note the cold-cranking amps (CCA) and reserve capacity
- Consult the Owner's Manual or the Vehicle Build Sheet for the specified battery type
- Inspect for Start-Stop indicators or badges in your dash or on the window sticker that suggest AGM usage
With this information, you can source the correct replacement and apply appropriate maintenance.
Maintenance and replacement considerations
Proper care extends the life of the 12-volt battery and prevents no-start conditions in everyday driving.
AGM vs flooded care
- AGM batteries typically require a charger compatible with AGM charging profiles; using a standard flooded-battery charger can reduce performance or lifespan
- Flooded batteries require periodic electrolyte checks and terminal maintenance to prevent corrosion
- Regardless of type, keep terminals clean, avoid deep discharges, and follow manufacturer guidelines for replacement intervals
Following these guidelines helps ensure reliable starts and steady electrical performance.
Summary
The Dodge Charger is powered by a 12-volt battery. Most models use a conventional flooded lead-acid unit, while some start-stop-equipped or high-demand trims employ an AGM battery. To know your specific car’s battery type, check the battery label, the manual, or the vehicle’s build sheet.
