Battery drained after 3 & 1/2 weeks standing, cranking slow, and throwing VSS Error - is this normal? Any help appreciated...

Just a thought, I was thinking about your bike and the Noco battery, then I remembered the one time I had an issue with my setup!! I do not have a lot of stuff plugged into my bike for the most part, but one time I had one of those chargers that you plug into the cigarette lighter that is in the back trunk which I was using to charge my phone, it has a little light on it, and I had Sena receiver which was also still on while it was sitting for a week or more - I went to start it and it was dead. I put the charger on it for a few minutes and got it going, went for a good ride and by the time I got home it was good! Needless to say, I haven't done that ever again, Yet!! By chance do you have anything like that plugged in that's not on keyed power?

Good thought, but I have nothing plugged in at all. I run a GPS but it is only plugged in while I am traveling, never when the bike is off.

If you have a USB power supply connected to your battery, and if you don't have one that cannot sense a load it can also drain the battery.

The USB power supply I have for my USB C cord for my Tackform mount cuts itself off when it does not have a load on it, so it does not drain the battery.

Thanks for all the input. Again, I have nothing extra attached directly to the battery or plugged into my USB ports. I did send an email directly to NOCO and received a response today. Not really very useful, but it did mention that for the first few rides you should plug in to a charger as that helps the battery condition itself properly. Also said that "After riding, plug the Genius2 in occasionally (especially for storage longer than 2–3 weeks) to keep the battery topped off." So, since I am making it a habit to just plug in the Genius2 after riding, should be good to go. Did have a nice little 1 hour ride yesterday even if it was a bit chilly and windy.
