What is the battery model for Audi A6?

Audi A6 is equipped with a Fengfan 58043 battery. Fengfan 58043: This battery has a voltage of 12V, capacity of 80AH, CCA-640A, dimensions of 315-175-190, and weighs 21.8KG. Precautions for using Audi A6 car battery are as follows: The normal service life varies from 1 to 8 years and is largely dependent on the vehicle's condition. If the vehicle's alternator charges normally and there is no leakage or grounding issue with the electrical system, the battery can generally last more than 3 years. If you notice that the battery is not charging properly, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. Therefore, it is not enough to measure the no-load voltage; the discharge current should also be measured.
My own Audi A6 is the 2018 2.0T version, which originally came with a Varta AGM start-stop battery, model H8 80Ah. During the last maintenance, the technician mentioned that this model is particularly crucial because vehicles with auto start-stop functionality must use AGM batteries—ordinary batteries can't handle the frequent current surges from repeated starts. Recently, I'm planning to replace the battery and specifically checked the manual. It turns out that the battery models vary significantly across different model years of the A6. For example, the 2015 model commonly uses a 12V 70Ah battery, while the 2020 hybrid version employs a specially designed lithium battery. It's essential to ensure compatibility when replacing the battery. Last time, someone in the car owners' group opted for a cheaper regular battery, and within less than six months, the start-stop function failed, ultimately costing double to replace it again. It's advisable to first check your car's production date and, ideally, remove the old battery to confirm the model by checking the label on its side.
