I've bought the BMW Motorrad charger for my 2018 1200GS while I'm not using it on salty roads. It's plugged directly into the aux socket and seemed to be doing the job. However, I've noticed sometimes when I go into the garage that it is charging and it's giving me a really low reading on the battery charge status. I've seen it down at 38% once. I thought it would fully charge the battery and then just give it small top ups every so often.
Does it sound like my charger is somehow abnormally discharging my battery?
Cheers
