No chance... I had fully charged it the last day it worked, and it worked great. I ran it about 45 minutes or so. Popped it on the charger before I hit the sack. The next morning, when I got to the head of the path I ride, I pushed the "on" button. Nothing. Nada.
So unless my charger somehow decided to become a DIScharger, that wouldn't be the reason.
Good idea, tho.
My LBS thinks its the connection on the top of the battery. Unfortunately, it's not servicable.
