To protect the car battery from low temepratures, I want to remove it from my old car and store it in the basement over winter and then recharge it before the next start of the season. The battery is from Bosch, model S4, 44 Ah, I think a stinkormal, maintenance-free car battery. See photo below. My questions. I always write basement, but by the slope position is half of the “cellar” a basement and a house connection room and the other half are two normal Room. The door from the basement room is always open and the room is relatively warm. So anything but a typical cold and damp basement. If I tilt the window in the basement room and in one of the rooms below, then probably some lutf movement would take place – might not hurt when loading, right? EDIT: Or sometimes asked quite differently – does the battery even have to get out of the car into the basement? The beetle is in a normal prefabricated garage, on the left and right there is Nachb argaragen, behind a wall with four small ventilation holes. It is located in the Rhine-Main area, where, as is well known, there are no hard winters.
