Sounds like a macho de-sulfate cycle.
This is one of those inventions that could make a huge environmental difference. If I didn't already spend my fun money this month, I'd buy one
Have we ever talked about the makerspace splitting purchases like these? Would 4 other guys be $50 interested instead of one of us being $250 interested? I'd commit to that for sure.
Something like that sounds good for mini-makerspace-crowdfunding, as this is a device that wouldn't need to be used all the time. I would be in for $50 also.

I wouldn't jump on this just yet. This is something I use to do back in the 80's - nothing new. It only works on Lead acid and NiCad's - and I really wouldn't say that it "works".
He also is way off on his data - think about how long you have owned your car (assuming you don't lease new every 2 years) How often have you changed the battery? My car is 9 years old - I've changed the battery once - not 3.6 times (9 / 2.5 = 3.6). He then states later that the average is 3 years. ?? Actually, The average life span of car batteries is 5 to 7 years. The average lifespan of Boat and RVs are 4 to 5 depending on usage.
What happens to your battery is that the plates sulfate a little with each charge/discharge cycle. As the sulfates build so does the resistance. as a result the battery can no longer perform as expected. What this device does is "cook" or "shake" the sulfation off the plates. This does in turn give you a little bit more life - but not that much. In my experience, about 6 months to a year for a car battery - IF the sulfation isn't very heavy. But that's not all. The sulfates don't just magically disappear - where does it go I wonder ?? Humm - could it be to the bottom of the battery? If it's heavy enough it can short the battery (because now it is connecting the plates together) and in extreme cases cause it to catch fire or explode.
When I was doing this way back in the stone age I found that the only time it really worked was on batteries that didn't really need it done. If you really want your battery to last longer - keep it charged.
My advice - buy a new battery. But if you really really want one - I can show you how to make it for less than $50.00, ( I wonder if an ATX power supply would work for this ).
In the RV industry they call this "Battery Equalization" and that really doesn't work either.
EDIT I think this says it all
The ReVolt3000 cannot correct bad chemistry, dried cells or damaged plates. Therefore, it works best on batteries which have not fallen into these conditions
In other words - the ReVolt3000 only works on good batteries.

Some things are meant to be closed. Your mind isn't one of them.
To be fair this process does work fairly well to rejuvenate those old NiCad screw gun batteries, or NiCad's for your robot. But it don't need to be that big. But a good NiCad charger has that feature built in. That's what I mainly used it for, I still ended up buying new batteries eventually.
