Audi R8 battery model is FSI standard engine 4.2L. Audi R8 battery lifespan: The battery lifespan of Audi R8 varies from 1 to 8 years, depending on the vehicle's condition. The battery, also known as the storage battery, uses external electrical energy to regenerate internal active substances during charging, storing electrical energy as chemical energy. When discharging is needed, it converts the chemical energy back into electrical energy output, similar to the principle of a mobile phone battery. Multiple electrical devices, avoid overload operation: With so many electrical devices in the Outback, when using these devices, try not to let the battery work under overload conditions, otherwise it will reduce the battery's lifespan.
My cousin's 2016 Audi R8 encountered the same issue when replacing the battery last year. After removing the trunk floor panel, we discovered the original battery was a 110 Ah Varta AGM battery with EFB marking, which is mandatory for vehicles with start-stop systems. Later, I checked the repair manual for him and found that pre-2015 models often used the 115D31R type, while newer models mostly adopt the H8 specification. I recommend taking a photo of the original battery label during disassembly. Last time, I almost bought the wrong one because I overlooked the cold cranking amp requirement of over 750A.
From a professional perspective, it's recommended to first check the original battery label as there are significant differences between R8 models from different years. Older V8 engine models often come with Bosch S5 115, while newer V10 models require AGM H8 specifications, with a suggested cold cranking amperage (CCA) starting from 800. When replacing it yourself, remember to wait for 15 minutes after disconnecting the power before proceeding, otherwise it may trigger an electronic parking fault code. In some modification cases, people have used the Optima Red Top 55-pound lightweight version, but this requires modifying the battery bracket.
