The Chrysler 300 uses a 12-volt automotive battery. In most configurations it’s a standard flooded lead-acid battery, while models with start-stop or mild-hybrid features may use an AGM (absorbent glass mat) or enhanced flooded battery designed for frequent cycling.
Overview of battery types in the Chrysler 300
Below is how the battery type can differ by feature and era, along with what to look for when replacing or maintaining the battery.
Note that the exact specification depends on the model year, trim, and whether the car has start-stop or a hybrid/electric option. The following categories summarize common configurations.
- Standard flooded 12-volt lead-acid battery: Most non-start-stop Chrysler 300s use this conventional design, which is easy to replace and widely available.
- AGM (absorbent glass mat) 12-volt battery: Some trims with automatic start-stop or higher electrical demand use an AGM battery, which handles repeated start cycles and provides better vibration resistance.
- EFB (enhanced flooded battery): An alternative to AGM used in some start-stop systems or to balance cost and performance on certain trims.
In plain terms, your 12-volt battery type in a Chrysler 300 is usually standard flood, with AGM or EFB installed where the car's electrical system demands more from the battery.
How to verify the battery type in your vehicle
To ensure you get the right replacement or understand your car's electrical needs, use these steps to confirm the exact battery type and group size for your Chrysler 300.
- Check the battery label under the hood for the part number, type (AGM or flooded), and the cold-cranking amps (CCA) rating.
- Consult the owner's manual or the battery specification page for your specific year and trim to identify the correct battery type and group size.
- Look for the battery group size on a sticker or stamping; common group sizes in full-size sedans vary, but your manual will specify the exact one.
- If your vehicle has Start-Stop or hybrid tech, expect an AGM or EFB battery; if not, a standard flooded unit is typically used.
Having the exact battery type helps with replacement, warranty, and ensuring compatibility with any accessories or stop-start features.
Maintenance and replacement considerations
Note on maintenance: AGM and EFB batteries may require different charging profiles and tool compatibility; always use the recommended charger and replacement part from the manufacturer or a reputable part supplier.
Summary
The 12-volt battery in a Chrysler 300 is typically a conventional 12V lead-acid unit, with some trims using AGM or EFB configurations for Start-Stop or higher electrical demand. Always verify the exact type by checking the battery label, owner's manual, or dealer specification for your model year and trim.
