ok guys....some little advise on the original-factory-fitted banner battery:
was driving in the high mountains again. parked the car outside over night and was a bit surprised the next morning when pushing the starter button! took over 40sec to start the engine. hhhmmmmm.....so end off story was, a 90% dead battery because of minuis 12 degreece over night!!! the battery froce over and killed it self (cell closure). so allways take your battery with you to the hotelroom, when its cold outside!!!!
