Yes, some Dodge Durango models use two energy storage units. The presence of a second battery depends on whether the vehicle is equipped with the eTorque mild-hybrid system, which adds a 48-volt battery pack in addition to the standard 12-volt starting battery. Models without eTorque typically have a single 12-volt battery.
In practice, the Durango's electrical setup can vary by year and trim. The eTorque system is designed to improve stop-start fuel economy and torque delivery, but it requires additional battery hardware that operates alongside the conventional 12-volt system.
Which Durangos have two batteries?
The information below describes when a Durango would have two energy storage units and how to identify them.
- Durango models equipped with the eTorque 48-volt mild-hybrid system. These trims use a second 48-volt battery pack in addition to the standard 12-volt starting battery.
- Durango models without eTorque generally rely on a single 12-volt battery for starting and standard electronics.
- You can verify the presence of the 48-volt system on the window sticker, owner's manual, or by checking for a label or component in the engine bay indicating "eTorque" or "48V." Some dealers can confirm via the VIN.
In short, a dual-battery setup is not universal in the Durango lineup; it exists on models with the eTorque mild-hybrid option and is absent on non-hybrid builds.
How to tell if your Durango has two batteries
Use these checks to confirm whether your Durango has the dual-battery arrangement:
- Open the hood and look for a second battery or a separate 48V battery pack in addition to the main 12V battery. The 48V pack is typically smaller and labeled with 48V or eTorque.
- Consult the window sticker or owner's manual for references to "eTorque" or "Mild Hybrid 48V."
- Ask a Dodge dealer or check the VIN-based build sheet, which will indicate whether the vehicle was equipped with the eTorque system.
Be aware that not all Durangos offer eTorque; even within the same generation, only specific trims include the dual-battery setup.
Maintenance and care for dual-battery Durangos
Dual-battery configurations require basic maintenance just like a single 12-volt battery, with additional attention to the 48-volt system if installed. Here are practical tips:
- Inspect both batteries for corrosion on terminals and ensure they are securely mounted.
- Keep the 12-volt battery fully charged; a failing 12V battery can affect the eTorque system's performance or start-stop capability.
- Follow the maintenance schedule for the vehicle and consult a technician for any "48V system fault" warnings.
Note: If the 48V system requires service, a dealer or qualified technician should handle it, as the high-voltage components require safety precautions.
Summary
In summary, whether a Dodge Durango has two batteries depends on the presence of the eTorque mild-hybrid system. Dual-battery configurations include a 12V starting battery plus a 48V battery pack, while non-eTorque models use only a single 12V battery. If you’re unsure, check the window sticker, owner's manual, or consult a Dodge dealer using your VIN. This distinction is important for maintenance, battery replacement, and understanding the vehicle’s fuel-efficiency features.
