WOW!!!! 11 years on the original battery. I wish I had your luck.

My original battery lasted 1 yr and 11months. Loaded the bike on the trailer for Thunder Beach, battery was fine. Tried to start the bike to unload and it was dead as a hammer.

 

only got 3 years out of mine.went bad after leaving lights on and running it dead.

 

I wound up checking the battery on the multimeter directly to the terminals which showed nothing. Also took it down to the shop to have it tested and their machine wouldn't even read it, it just said "replace battery" getting a New gel battery today#
