I dont really know... Tough to say, as so many other things effect battery life, like time at temperature. For every 8C above 25 degrees celcius, the life of your battery will decrease by 50%!
It is well established that long durations at high voltage (quite high, possibly 16+V) at very low current can help to dissolve hard sulphate crystals on the plates.
The question is if these desulfators' small pulses, seemingly taken from the battery and then injected back (when the car isnt on) are going to ultimately effect your SOC which can be harmful too.
I personally would treat your battery nice (dont pull load from lights, radio, etc when the car isnt on), top it off with a real charger now and again, keep it cool when you can, etc., and it will last 7-10 years, which is all you can really ask for. Telecon UPS batteries only have service life of 10-15 years practically speaking, and they often live in climate controlled buildings on float charge without ever discharging at all.
