I've had my motobatt for approximately 2yrs, I have 5 motorcycle, GL1800 Honda, Kawasaki Concourse 14, Yamaha FJR and two 1150 BMWs, Bmw are Junk, but the Motobatt trickle charger is awesome, they don't charge from dead and 99% of trickle charges will NOT charge a dead battery. Buy a $200 manual charger to do that and stop mixing Apple's and oranges together. Since I've had the motivator None of the motorcycle have ever had a battery issue and I leave the motorcycle on the motivator year round when not riding. I don't worry about them any more. I have purchased some of the extensions 12' and the leads were crossed right out of the box, so I had to cut the extension and soldier back but then they worked fine. I recommend the motorbatt.
