The 2018 Chrysler 300 uses a standard 12-volt automotive battery based on conventional lead-acid chemistry. It is typically a maintenance-free, sealed design and not a high-voltage or lithium-ion pack. Exact specifications such as cold-cranking amps (CCA) and group size can vary by trim and production batch, so the label on your battery or your owner’s manual should be consulted for precise numbers.
Battery type and general specs
The car’s electrical system relies on a traditional 12V lead-acid battery for starting and power to accessories. This is the same class of battery used in most non-hybrid gasoline vehicles. It’s usually maintenance-free, with sealed terminals, but you should check the label for details about CCA and capacity.
Typical characteristics you can expect are:
- Voltage: 12V
- Chemistry: lead-acid (flooded or maintenance-free sealed)
- Performance: designed for starting the engine and supporting on-board electronics
- Maintenance: usually maintenance-free; periodic inspection of terminals is recommended
- Replacement: match or exceed OEM CCA and ensure proper fit for the battery tray; exact size varies by trim
Because production changes may occur, always verify with the battery label or dealership records for your specific vehicle.
How to verify your exact battery in a 2018 Chrysler 300
To confirm the precise battery installed in your car, use the following steps. This will help you identify the group size, CCA rating, and whether an aftermarket replacement is appropriate.
- Open the hood and locate the battery; inspect the top label for the group size (e.g., a code) and CCA rating.
- Record the part number and check the owner's manual or service booklet for OEM specifications.
- Compare the battery label with OEM replacement recommendations from Chrysler/Fiat dealerships or parts catalogs.
- If planning a replacement, choose a battery with equal or higher CCA and the same physical fit for the tray and terminal configuration.
Note: AGM batteries are not standard in most 2018 Chrysler 300 configurations, but certain regional or dealer-issued options or extreme climates might employ different choices. Always confirm via the battery label or dealer documentation.
Summary
The 2018 Chrysler 300 uses a conventional 12-volt lead-acid automotive battery, usually maintenance-free, for starting and electrical systems. The exact CCA and group size vary by trim, so check the battery label or the owner's manual to confirm the precise specifications when replacing or servicing it. Overall, this is standard for gasoline-powered Chrysler 300 models of that year.
