There is a rather large misconception that "Battery Tenders" are a useful tool to keep a "Trickle Charge" on our precious Ducati batteries.

I hope this has helped some realize that these products are FAR SUPERIOR to any normal Battery Chargers found at your local Bike Shops! Stay safe and ride it like you own it -
