I bought the Triumph Battery Optimizer. However, it's interesting that in the Owner's manual, it states "Always remove the battery from the motorcycle" when charging it. This seems to negate using the Battery Optimizer while the battery is still in the bike (which is why I bought it in the first place).
Don't worry about, you're not charging it, you're just "optimising" it!
