I can answer that- NO - but do it anyway.
Unhook the battery for two weeks and do not put it on a charger. Take a voltage reading before and after.
How much did it drop in two weeks with one post disconnected and no charger?
New batteries can be defective too. What new battery do you have and how new?
Matt- Did you paint your bike yourself. It looks familiar.
Thanks Mike. I do not know the maker of the current battery. Although I do know that it is sealed. The other one that went bad for being off the charger for awhile was not (that battery was only two years old). Each experienced the same drain.
Regarding the paint, I painted it myself. I was told it looks a lot like another member; I think his name his Snarf.
