Where is the battery located in an Audi A6?

In the older models of the Audi A6, the battery is located under the rear seats. For the newer A6 models, the battery is in the trunk at the rear of the car. There is a handle on the floor panel; lifting it reveals the battery and the spare tire. The Audi A6 is a luxury vehicle produced by Audi, with dimensions of 5012 mm in length, 1855 mm in width, and 1485 mm in height, and a wheelbase of 2945 mm. The Audi A6 incorporates Audi's advanced global high-tech proprietary technologies, further enriching its luxurious features and endowing it with exceptional sporty characteristics. From design to performance, it embodies flawless quality, characterized by being more luxurious, dynamic, and mature.
The battery location of the Audi A6 depends on the model year. Based on my experience with many cases in recent years, older models before 2010 usually have the battery in the engine compartment – you can find the black box at the front right when opening the hood. However, for versions after 2011, most batteries were relocated to the trunk to balance the vehicle's weight. Lift the floor panel, and you'll find a plastic cover on the right side of the spare tire or the left rear side. Last week, a friend's car suddenly wouldn't start, and we found the battery buried under clutter in the trunk, with oxidized positive terminals. When checking it yourself, be careful not to use excessive force when removing the cover, as the plastic clips can break easily. If you're completely inexperienced, it's better not to replace it yourself – Audi's electronic systems are complex, and disconnecting the battery might trigger fault codes.
Five years of driving an Audi A6 taught me that locating the battery starts with identifying the model year. In my 2020 model, the battery hides under the trunk floor mat—just remove the sound insulation to reveal it. Meanwhile, my friend's older version sits in the battery tray on the right side of the engine bay. Crucial reminder: Models with auto start-stop require EFB or AGM-specific batteries; regular ones won't last. For DIY inspection, first empty the trunk, then pry open the black plastic cover with a flathead screwdriver. Check electrode terminals for green corrosion (clean with baking soda solution if found). Note: After disconnecting power, reset windows by holding their switches briefly.
The battery location of the Audi A6 has undergone significant changes, and I've studied the specific design logic. Previously, it was placed in the engine compartment for wiring convenience, but now relocating it to the trunk improves the front-to-rear weight distribution, enhancing handling. When actually locating it: lift the trunk floor panel and look at the right-side compartment, or remove the foam blocks around the spare tire. For hybrid versions, it might be under the front passenger seat. Last week, while helping a neighbor with an inspection, I discovered a trick—turn on the interior lighting and then feel the battery terminals; a slight vibration indicates the circuit is live. It's not recommended to perform this operation on rainy days, as water accumulation in the trunk could seep into the battery compartment and cause a short circuit.
