Hello dear community My battery in the Seat Leon 5F is now 8 years old and still the one that was installed in the vehicle at new purchase. For winter I have now charged the battery for the first time, because it was 60 percent according to the menu in the vehicle. Since then it has been constantly at 80 percent and does not cause any problems for years. Now there should be very unusual temperatures in the west here all week, partly minus 15 degrees at night and during the day permanent frost. To hang on to the charger for protection overnight in order not to have to experience a nasty surprise? Look forward to your opinion
