Just replaced the battery in my 02 '1500' Drifter. The battery was installed by the previous owner about 18 months ago. The brand is a Pirate Battery. From what I could find on it was that the warranty issued was only for 18 months so I guess that is about right as it would not hold a charge anymore as I tried charging it. Put in a new battery and bike started right up. Has anyone heard of this brand? And if so, any opinion of it?
