I bought this for my 2017 BMW R1200RT to charge my bike via Cambus. I haven't ridden in a while due to COVID and the battery stopped turning the bike. The bike turned on and everything was fine, just not enough power to flip it. As many have said, the lights on this thing are incredibly mysterious. Even after reading the manual I wasn't 100% sure what this charger was doing at any given point. I went ahead and just plugged it into the port and let it do its thing. After about 8 hours I was finally able to identify a phase of the flashing lights. It was the one showing a solid green light, indicating a good charge/tested battery. Once it does, it goes into pulsed charge mode, then seems to retest and just repeat the process. So you can always connect it to your bike. So while the charger couldn't understand what it was doing. At the end of the day it charged my battery and I was able to start it with no problems. It's a good charger, but don't expect to always know what it's doing at different stages.
