I want to upgrade the battery in my Audi A7 to increase its range. I'm curious what the max size battery is that will fit in the vehicle's designated battery location without any modification to the car's wiring or electronics.
ReplyAccording to official Audi documentation, the largest compatible battery for the 2021 Audi A7 is a 12V 95Ah battery. However, many owners have reported successful installations of even larger batteries, such as the 12V 110Ah, with minor modifications.
I suggest consulting with a certified mechanic or dealership before making any modifications to your Audi A7's battery size. They can provide specific recommendations for your vehicle and ensure compatibility with your car's wiring and electronics.
