I used a standard tender on my last Harley Battery and got 8 years out of the original factory battery.......not too bad if you ask me
Desulfation feature, that's interesting. Another way of saying equalize charge I'm guessing. The only problem with commercial batteries is there isn't enough room at the bottom of the cell to handle much lead sulfate, so in a short amount of time you'll end up with a short Industrial batteries typically have inches in this area and can easily handle repetitive equalize charges to shake off the iron sulfate without causing problems.

I may try a tender on my Harley. 2 batteries now in 2 years and probably only 3 rides
