Managing battery for extended period of non-use of the car
I owned a 2013 Passat. I will be away for a long period (more than a month) and the car will be at the car park.
Question: should I (a) disconnect the battery and run the risk of instrumentation issue during restart or (b) leave it as is and then do a jump start when I return (by which time battery could be dead and may require a replacement, and still messes up the instrumentation)? Is there another solution?
