It sure does desulphation, basically it try's to remove sulphates from the lead plates of the battery restoring battery capacity. It does this with very cleaver charging programme, pulsing voltage I believe but only to a point, if the battery drops below something like 10v (don't quote me on this figure) the battery is shot. They also auto detect what type of battery you've got WET, MF, Ca/Ca, AGM and GEL, think that's all of the current types, all of which are charged slightly differently.
A quality well maintained battery will last for many years, I've got a 15yr work car it's still got the same battery from new. It's used regularly and charged twice a year, never allow a battery to become discharged for long. Some of these cheap Chinese gel batteries most stealers flog are crap, lasting no more than a couple years at best, if allowed to discharge this can be months, I kid you not.
