ITS just not that easy to say if they work well or not,, You cant just make blanket statements saying yes or no There are thousands of people that swear by them saying they really do work there are just as many others that say that using additives does nothing
I have never found anyone that says using additives damages a battery.
Its very difficult to ever do an exact side by side comparison showing they work or not.
If you can get the additives cheap then why not use them? as what is there to lose?
There are some battery sellers that will even extend the warranty of the battery if you use the additive they sell.
"I'd rather race without tires then [sic] without VX-6 in my battery!"
Since the 1950’s chemical additives have been used to reduce lead sulfate build up on plates and improve battery condition when added to the electrolyte of a vented lead-acid battery. Such treatments are rarely, if ever, effective. Two compounds used for such purposes are Epsom salts and EDTA. Epsom salts reduces the internal resistance in a weak or damaged battery and may allow a small amount of extended life. EDTA can be used to dissolve the sulfate deposits of heavily discharged plates. However, the dissolved material is then no longer available to participate in the normal charge/discharge cycle, so a battery temporarily revived with EDTA should not be expected to have normal life expectancy. Residual EDTA in the lead-acid cell forms organic acids which will accelerate corrosion of the lead plates and internal connectors.
Active material changes physical form during discharge, resulting in plate growth, distortion of the active material, and shedding of active material. Once the active material has fallen out of the plates, it cannot be restored into position by any chemical treatment. Similarly, internal physical problems such as cracked plates, corroded connectors, or damaged separators cannot be restored chemically.

Floating an oil on top of the electrolyte makes sense to me, and I'd appreciate hearing if that actually makes any difference.
I tried an additive in my semi-truck batteries a few decades ago. The batterys were getting old (but still worked to start the truck) and I read on the label how they'd be "rejuvenated" by just adding the stuff. I did. The batteries were then stone-cold dead within 2 days.
I haven't tried any battery additives since.

If additives could significantly improve the performance or longevity of a battery, why wouldn't they used in the manufacture of the battery?

On the other hand, Amplitude Modulated Pulses at the resonance frequency of the crystals to shatter the covalent bonds that hold it together. This allows the lead sulfate to be reconverted once the battery is charged.

Epson salt solution will dissolve crystalized lead sulfate. It will drop to bottom of battery so you will not recover the loss. Only helps on a deep cycle battery known to have not been charged for nine to twelve months or more suffering from hardened sulfation. At least is gets more plate area exposed. You will have a reduced SG since the lead sulfate takes acid along with the lead bond.
Pulse charger can help for softer sulfation by getting peak current up without subjecting the battery to high average current overcharge.
As to 'resonating' crystals to break them up. Even if there is some truth to it there are so many variable to size of battery and needed current density it is very doubtful if any fixed desulfator could get it right.
