Fooled myself. My original GSC 10 battery lasted over 2 years. Figured I should proactively replace it. I replaced it and the new one died on my 2nd ride. (About 5 days). I am guessing that it "forgot" how to power down. Looked for some information and found nothing useful. I have put another new battery in the unit and paired it again with my 500. There is no way to tell if the thing is powered down externally. I guess I will see how long this battery lasts. So the question is: Does anyone know if there is a procedure that needs to be performed during or after replacing the GSC 10 battery so that the unit powers down again after rides. I never had any issues with where the magnets were located for the past 2 years, never paid attention but typically the cadence magnet would not have been near the GSC10.
Thanks for any suggestions.
