From day one I always plugged my Spyder in to a Battery Tender after each ride......I noticed it always took about 10minutes to roll from the charge mode to the maintain mode.....this past week I rode every day but did not plug up to the Tender.....today after a one hour ride I pluged in to the Tender and after 3 hours it is still in a charge mode......my other bikes roll right to maintain whether on or off their tenders for any length of time.....Anyone else notice the charging system on the Spyder does not seem to maintain the battery at full charge?? The Spyder cranks good and strong....battery seems up.....maybe this is the nature of the unit:dontknow:
