Hello everyone, I am now also proud owner of an Audi R8 V8 FSi bj.2007 420 hp. Now I am faced with the problem of getting the vehicle / battery problem-free over the winter. And I have to buy a CTEK maintenance device to bring the battery over the winter. Has someone already made the experience with a product from the aforementioned manufacturer? If yes you can recommend me a device that is best suited for the vehicle? And above all how did you proceed at the time of joining eat and how long did you leave the vehicle unattended? Thank you in advance
