The Dodge Charger relies on a conventional 12-volt starting battery for daily operation, with an optional 48-volt lithium-ion pack for its mild-hybrid eTorque system on select engines.
Battery system overview
The Charger’s electrical architecture blends a traditional 12-volt battery with a higher-voltage option on certain trims. Here’s how each part functions and what it means for owners and maintenance.
12-volt starter battery
The 12-volt battery powers the engine start, ignition, lights, infotainment, and other electronics when the engine is off or during low-load situations. In most Chargers, this is a lead-acid battery, with some trims using an absorbed glass mat (AGM) variant for improved durability and cycling performance.
- 12-volt lead-acid battery powers starting and most daily electronics when the engine is off or idling.
- Commonly located under the hood and connected to the alternator and vehicle power systems.
Across all configurations, the 12-volt battery remains the essential power source for routine vehicle functions.
48-volt eTorque battery
On models equipped with the eTorque mild-hybrid system, a separate 48-volt lithium-ion battery pack supports the belt-driven starter generator, stop-start functionality, and mild-hybrid torque assistance. This pack works alongside the 12-volt system and is not intended to replace it.
- 48-volt lithium-ion battery powers the eTorque starter generator and enhances start-stop performance and torque delivery during acceleration.
- Part of a dedicated 48V electrical subsystem that supplements, rather than replaces, the traditional 12V system.
In summary, the Charger uses a standard 12V battery for everyday operation, with an optional 48V lithium-ion pack on eTorque-equipped trims to enable mild-hybrid capabilities.
What this means for maintenance and ownership
For most owners, the 12-volt battery is the primary maintenance item and replacement point. If your Charger has the eTorque system, the 48-volt pack is generally serviced through dealership maintenance and is less frequently replaced, though it may require checks during major service intervals or if hybrid performance problems arise.
Summary
The Dodge Charger relies on a traditional 12-volt lead-acid battery for starting and standard electronics, with an optional 48-volt lithium-ion battery pack used on eTorque-equipped trims to support mild-hybrid features.
How do I know my car battery type?
While you could grab a ruler and attempt to measure the exact width and height of your current car battery, pop the hood and simply look for "Group Size" printed on the label of the battery or check your owner's manual.
