Not all Durangos have two batteries. Only models equipped with the eTorque mild-hybrid system use a second battery alongside the standard 12V battery, while non-hybrid Durangos rely on a single 12V battery.
The Dodge Durango's electrical system varies by powertrain. In recent years, a mild-hybrid setup known as eTorque has been offered on certain engines, bringing a second, 48-volt battery into the mix to power the hybrid starter/generator and assist with torque delivery. Other Durango configurations continue to use a traditional 12-volt battery for normal vehicle electronics and starting.
Understanding the Durango electrical system
Most traditional vehicles use a single 12-volt battery to supply power for lights, the starter, and onboard electronics. When a mild-hybrid system such as eTorque is installed, a separate 48-volt battery pack works with a belt-driven starter generator (ISG) to provide torque assist, regenerative braking, and smoother start-stop operation. This pairing means the Durango can have two distinct battery systems, depending on the powertrain.
Two batteries: which Durango models have them?
Below is a general guide to when Durangos tend to have two batteries. Availability can vary by model year, trim, and market.
- Durango models with the eTorque mild-hybrid system (introduced on certain engines in later 2010s and continued on various trims) typically have two batteries: a standard 12V battery and a 48V lithium-ion battery pack powering the eTorque system.
- Durango models without the eTorque system or older, non-hybrid powertrains use a single 12V battery for all vehicle electronics.
In short, the presence of two batteries indicates the presence of the eTorque mild-hybrid system; if your Durango does not have eTorque, you should see only one 12V battery under the hood. For a definitive answer on a specific VIN or trim, consult the owner’s manual or a dealer.
How to identify on your vehicle
To verify whether your Durango has two battery systems, you can inspect the vehicle or check service documentation. Look for a second battery or a dedicated 48V battery pack (often labeled or described in service documentation as the eTorque 48V system). The 12V battery is the standard one you’d expect for starting and electronics, while the 48V pack powers the mild-hybrid components. If you’re unsure, a quick VIN lookup with a dealer or service manual can confirm the exact powertrain configuration.
Summary
The Dodge Durango does not universally include two batteries. Two-battery configurations exist on models equipped with the eTorque mild-hybrid system (a 12V battery plus a 48V battery), while non-hybrid Durangos run on a single 12V battery. If you’re shopping or maintaining a Durango, check whether your powertrain includes eTorque to determine the battery setup.
