Question about Ctek MXS 5.0 (CH version)

HARLEY DAVIDSON RIDERS!!! This charger fully recharged my dead battery without loosening any screw (works with the top modern Harleys, but also with older models). But it still needs a small adapter device (here: https://www.galaxus.ch/de/s4/product/ctek-comfort-indicator-pigtail-mit-batteriestandsanzeige-12v-batterieladegeraet-10125864?supplier=406802). A real dream for over winter. There are many modes (charge battery, "hibernate" battery, maintain battery, etc.). On the side of the Harley, a small cable peeks out. Remove the cap, plug it in and DONE. Really good! :)
