Hello, since my battery has already exceeded the 5 year limit, I would like to replace it before the beginning of winter. (Not least because it can come to various software problems due to an empty battery). Now I have already found some change instructions over the SuFu. However, all these instructions go to it, if problems have already arisen due to wrong battery changes, or various units of the instruments have failed. My question: How wec hsle I correctly my vehicle battery without getting any problems with the electrics? Bzw., what do I have to take into account? BTW: Which battery brand would you recommend? Thank you!!! LG, Nordisk.
