Where the Battery Is Located in a 2019 Audi Q7

In a 2019 Audi Q7, the main 12‑volt battery is located in the rear of the vehicle, beneath the cargo area floor on the right-hand (passenger) side, rather than under the hood. This design is typical for modern premium SUVs to save space in the engine bay and improve weight distribution.

Understanding the Battery Layout in the 2019 Audi Q7

The 2019 Audi Q7, built on the MLB Evo platform, uses a rear-mounted battery layout for its primary 12‑volt system. When owners open the hood and don’t see a conventional battery, they often assume something is missing or hidden; in reality, Audi has relocated the main battery to the rear cargo area while providing dedicated jump-start points in the engine compartment for convenience.

Main 12‑Volt Battery Location

The main 12‑volt battery powers the majority of the vehicle’s electrical systems, including starting, lighting, infotainment, and control modules. Knowing its exact location is important for replacement, inspection, or any work involving the electrical system.

Accessing the Main Battery in the Cargo Area

To help you visualize and safely reach the main battery in a 2019 Audi Q7, here is a step-by-step explanation of where it sits and how to get to it inside the cargo area.

• Open the rear tailgate to access the cargo compartment.
• Lift the cargo floor panel: this is the removable or hinged floor section that covers the spare tire or storage well.
• Look to the right-hand (passenger) side beneath the floor: the battery is mounted in a recessed compartment along the right side of the spare wheel/storage area.
• Remove or tilt any side trim cover or plastic panel on the right side if present; some versions have an additional cover over the battery for protection and sound insulation.
• Once exposed, you will see the 12‑volt battery assembly, including cables, hold-down bracket, and nearby electronics (such as a control module or fuse elements, depending on equipment).

This rear, right-side location under the cargo floor is where Audi technicians and parts diagrams show the main battery for the 2019 Q7, and it’s the area owners should access for battery replacement or direct work on the terminals.

Under-Hood Jump-Start Terminals

Many owners expect to find and access the battery directly in the engine bay. Because the Q7’s battery is in the rear, Audi provides dedicated jump-start or charging points under the hood so that you don’t have to use the battery itself for routine boosting.

Finding the Jump-Start Points

Rather than searching for the entire battery under the hood, drivers should locate the designed positive and negative terminals intended for jump-starting or charging.

• Open the hood and secure it safely.
• Locate the positive (+) terminal: it is typically near the cowl or on one side of the engine bay, often marked with a red cover or a “+” symbol; you may need to flip open a small plastic cap.
• Locate a solid negative (–) ground point: this is generally a designated metal stud or bracket in the engine bay, often marked with a ground symbol and specifically identified in the owner’s manual.
• For jump-starting, connect the booster cables or charger to these under-hood points rather than directly to the rear battery.

Using these official jump-start points is safer and avoids removing cargo panels just to attach cables, which is why Audi incorporates them despite the rear-mounted main battery.

Why Audi Puts the Battery in the Rear

The battery’s rear placement in the 2019 Q7 is not accidental; it is part of Audi’s engineering approach to space management, handling, and safety in a large SUV.

Engineering Reasons for Rear Battery Placement

Several technical and practical factors influence the decision to move the battery from the engine bay to the cargo area in vehicles like the Q7.

• Improved weight distribution: Shifting the heavy battery toward the rear helps balance weight between the front and rear axles, which can support more stable handling in a large, front-heavy SUV.
• More room under the hood: The Q7’s engine bay is densely packed with turbocharged engines, cooling systems, and emissions hardware, making rear placement more practical.
• Thermal protection: Keeping the battery away from constant engine heat can extend its service life and performance consistency.
• Crash safety and packaging: Integrating the battery into the rear structure lets engineers protect it within controlled crumple zones and interior packaging.

These considerations mean the rear is often a better location for modern premium vehicles’ batteries, even if it feels less intuitive to owners familiar with older layouts.

Important Notes for Owners Working on the Battery

Because the 2019 Audi Q7 is heavily computerized, servicing or replacing the battery is not as simple as swapping one part for another. There are technical details and cautions to consider before tackling the job yourself.

Service and Safety Considerations

Owners planning to access or replace the rear-mounted battery should understand the implications for the vehicle’s electronics and their own safety.

• Battery registration/coding: Modern Audis often require battery adaptation via diagnostic software when a new battery is installed (especially if the capacity, type, or brand changes). This allows the energy management system to charge it correctly.
• Correct specification: The replacement battery must match Audi’s specified type (often an AGM or EFB battery) and capacity for the Q7’s electrical load and start/stop functions, where equipped.
• Safety while disconnecting: Always turn the ignition fully off, remove the key or switch off the start/stop button, close doors or ensure no consumers are active, and disconnect the negative terminal first to reduce short-circuit risk.
• Data loss and reset: Disconnecting the battery can reset clocks, radio settings, and may cause temporary warning lights until systems reinitialize. In some cases, windows and sunroof may need normalization per the manual.
• Professional service recommended: Because of the integration with control modules and the need for potential coding, Audi dealers or qualified independent specialists are often the safest option for battery replacement.

Keeping these points in mind helps ensure that any battery-related work on a 2019 Q7 maintains both safety and full functionality of the vehicle’s electrical systems.

Summary

In the 2019 Audi Q7, the primary 12‑volt battery is not in the engine bay but in the rear cargo area, under the floor on the right-hand (passenger) side. Audi provides dedicated under-hood jump-start terminals so drivers rarely need direct access to the battery itself. This rear placement supports better weight distribution, frees up space under the hood, and helps manage heat and safety more effectively. Owners who need to service or replace the battery should be mindful of proper access steps, electrical safety, correct battery specification, and, in many cases, the requirement for electronic adaptation or coding after installation.

Where is the battery located on an Audi?

The Audi battery is most commonly located in the trunk under the spare tire, accessed by lifting the carpeted floor, removing the spare tire, and then taking out a plastic cover. For some models, like the Q7, the battery is under the front driver’s seat. On very rare occasions, it could be under the hood in an older model. If the battery is dead and won’t open the trunk, use the designated jump start terminals in the engine bay.

For most Audis (A4, A5, A8, S5, etc.)

1. Open the trunk: Use the key fob or the button on the driver’s door panel to open the trunk. If the battery is completely dead, you will need to use the jump-start points in the engine bay to open the trunk first (see below). 
2. Access the spare tire: Lift the trunk’s carpeted floor mat to reveal the spare tire. 
3. Remove the spare tire: Unscrew the central nut holding the spare tire in place and lift it out of the trunk. 
4. Locate the battery: The battery will now be visible underneath where the spare tire was. There may be a plastic cover or other components to remove before you can get to the battery itself. 

For Audi Q7

• The battery is located under the front driver’s seat. 
• You may need to open a compartment or lift a panel to access it. 

If the battery is dead and the trunk won’t open

• You can use the jump-start terminals under the hood.
• Open the hood and locate the positive (+) terminal, which is often under a red cover marked with a ‘+’ symbol.
• Find a good ground point on the engine or body (an unpainted metal surface).
• Follow proper jump-starting procedures, connecting the positive and negative terminals correctly, to give the battery enough power to open the trunk.
