maybe 15mi, I dont recall, but at LEAST a commute drive home from work.Before you parked it how much did you drive the bike each time you started it? FWIW my 2009 GS had two batteries go bad in the first year I had the bike. Took the second one apart and found the internal tie straps between cells to be very flimsy. Needless to say another BMW battery did not go back in.
The system was "on" for maybe two minutes doing a read off the ECU, that was it.
