It may be your Spinner that's doing this with your charger. With the Spinner II we've found that it does strange things when charging. What we've worked out as a work-around is to put the Spinner on the charger. Wait a few minutes and then take it off the charger then put it back on right away. The normal charging cycle will go through. We haven't figured out why the Spinner II does this, but we've learned to live with it.
