I used a Battery Tender Jr on all my Harley's and have used an Optimate 4 on all my BMW's plugged through the CANBus port. I have a pigtail directly connected to the battery and could do that if I needed to, but so far, no problem.
The only battery I have had to replace was one on a 7 year old Harley, it was the original 36 month battery.
