Good morning dear forum members I have a problem, I don’t know yet with what. Have a Dethleffs 8000 XXL on an Iveco. As every year I run the heating in winter very small however on 220 V wanted to unpack it yesterday (plane) the lifting supports (electric) in and nothing works. Have tested the two gel batteries and my indicator shows me zero Kommanix, I bought the batteries last year. Replacement battery connected and it works. Mei a question actually the charger charges the batteries when I connect 220V. Have connected electric block EBL 99 from Scheidt with an additional charger. All fuses checked on the device all in order. Can check today if really 220V arrive at the electric block. Maybe someone has had the same problem and can give me useful tips. My second question I can recharge gel batteries that are completely emptied or are broken. Please forgive me and don’t make so many foreign words or abbreviations around my ears I am an absolute layman in the field, trust me everywhere but don’t understand it immediately. Thank you very much for your answers. LG Rüdiger
