Annie’s F800GS, went for a ride of about 60 miles. Bike started normally at our place and after one stop during the ride. Got home and cut off the engine and shortly thereafter tried to start without success. Put a meter on the battery and it was at 11.4 volts. Charged it overnight and it was at 13.2 volts. Reconnected battery and started the bike. The battery dropped to 11.4 volts under load. Bike was charging at 14.2 volts at idle. The battery was at 13 volts after shutting off the engine.
About 8 years ago we had a battery that would preform normally for awhile and then seem to lose enough charge to start the bike. We were on a ten day trip and I had to jump her bike once or twice a day. I was told that AGM batteries can have a connection between cells fail, thus reducing the charge available, and then the break can temporarily weld itself when the battery is under load. This explanation seems to describe what happened.
So, is there another plausible explanation for what is happening now? That being, a battery that was under charged after a ride on a bike with a functioning charging system, but took and is now holding a charge. Anyone else have an intermittent failure on a battery?
