Hello, everyone from Spain: Have a short question today, my battery charger – constant continuous charge – warms up from time to time according to the car application, i.e. with that of my son (Ford Fusion) warms up and charges with my Tiguan without this problem. Sometimes it is different. OK with my son or from a neighbor and bad with mine. If it warms up, the battery charges – or signs the device – that the battery is not fully charged after hours. Woran kan n hang it ? Problem with the cable ? Even from the device ? How can I check it ? Thank you all in advance for your gifted support. Greetings from Spain. Spain
