Have a 95 Knaus-WoWa, 530 tk Sport. There is the battery next to the boiler in the children’s storage room. So far no topic, now the TÜV has objected. So where with the battery? In plastic pot? Is in size 420 x 200 x 200, (battery is 390-80-200) – does not fit quite in the width, because drain valve for boiler is in the way. In the cabinet to the charger? Must first the wheel box be built over. What do you do? Who knows exact regulations – can I use the Bat terie can also be converted with wood (share a damper box), lead ventilation hose down and finished? Or who better solved this and can give advice? Thank you in advance!
