The same goes for me with many systems. I mean if a system is not really needed for everyday life it’s not a big issue, but important systems like the leisure batteries, there I want to have as much feedback and influence as possible – and thats o the case with maintenance free AGM batteries. So next time – wet deep cyclers. Not as convenient, but speaking from what I read, a lot more sturdy.
But back to the Megapulse:
This thing is on the market for over 15 years now and several studies, as well as reviews from private people proofed the unit to be working, although at first it raised a lot of suspicion amongst people who thought its a rip of scheme for people who believe in magnetic bracelets for better health and the like. But in the meanwhile the general consensus seems to be that it actually does what i claims to do.
Basically it operates on the principle of sending many pulses (8000 per second) into the battery at the frequency the sulfation crystals have on their own, which loosens and destroys them (as far as I understood) – because when you hit something with its own frequency, it goes bonkers (basically the same thing why some glasses explode when some opera singers sing). The main problem with a sulfation is theat lead acid batteries, when not fully charged, develop a kind of layer of these crystals on their lead plates, so there is less and less remaining place for the chemical reaction in the battery and this unit kicks them in the arse.
