The 2018 Dodge Charger uses a traditional 12-volt lead-acid automotive battery for starting the engine and powering the vehicle’s electrical systems. There is no high-voltage traction battery like in a hybrid or electric vehicle in standard Charger models.
The Charger’s battery is designed to supply power to the ignition system, lights, and onboard electronics. While all trims share this 12-volt power source, there can be minor variations in battery size or labeling based on trim level and regional specifications. For exact details, always refer to the owner’s manual or the under-hood battery sticker.
Key characteristics of the Charger’s 12-volt battery
What to know about the battery’s fundamentals before you buy or replace it:
- Type: 12-volt automotive battery (lead-acid), typically sealed and maintenance-free.
- Purpose: Starts the engine and runs the vehicle’s electrical accessories and systems.
- Variations: Most trims use a conventional lead-acid battery; some configurations may use an AGM (absorbed glass mat) variant, though this is not universal across all 2018 Chargers.
- Replacement basics: Choose a battery with similar electrical ratings (group size, CCA, and reserve capacity) as specified for your model; consult the owner’s manual or dealer for the exact fit.
These points summarize the general battery setup for the 2018 Charger and help guide replacement or maintenance decisions.
How to identify and replace the battery in your Charger
Before you replace or inspect the battery, verify the exact specifications for your particular trim and region:
- Check the under-hood sticker or battery label for the group size and CCA (cold-cranking amps) rating.
- Compare the existing battery’s part number or size (often printed on the top or side) with OEM replacements.
- When purchasing a replacement, match group size and CCA to the specifications in your manual; consider optional features like AGM if your model lists them.
- Have a certified technician perform battery installation if you’re unsure about terminal connections or safety procedures.
If in doubt, consult a dealer or automotive service professional to ensure you select the correct type and size for your 2018 Charger.
Summary
In short, the 2018 Dodge Charger relies on a standard 12-volt lead-acid automotive battery, with potential minor variations by trim or region. There is no high-voltage battery associated with hybrid or electric propulsion in the stock Charger lineup. For replacements, verify the group size and CCA from the manual or sticker, and opt for a maintenance-free, sealed battery that matches OEM specifications.
