From 1st year college level general chemistry:

A salt (there are many) like Magnesium Sulfate (Epsom Salt) is what is left over after you neutralize an acid, like sulfuric acid. (battery electrolyte) That's exactly what you DON'T want more of inside your wet cell batteries. The chemical engineers who have been designing and building wet cell batteries for over a hundred years all know that. I guess everyone else didn't get the memo!

Mmmmmmmmmm...

Oatmeal and black pepper in the radiator. Quaker oats and Indian fresh Telecherry ground pepper are best. Trust me [emoticon]

I don't believe it's snake oil, there's actual peer reviewed studies behind it the process. however it's not going to turn a destroyed battery back to new, which is pointed out in those studies.

Epsom "salt" has the disadvantage of being touted as a cure-all for a number of medical conditions as well, a tiny grain of truth mixed it with a lot of misinformation.

One gearloose study had me pulling plates out of a destroyed L-16

Immerse in monel vessel with 1.300 density H2SO4 (2liters)

Add approx 4 oz of magnesium sulfate

Heat to 90 degrees celsius. Remain for ? days (I forgot it was several)

Under 10x loupe, no change in crystalline structure. Waste of time other than the test yielded a hard finding.

Some low intensity tests like maintaining 16.0 volts for 2 weeks with Magnesium sulfate yielded 100% plate shedding (stripping) of plate material. Hardened sulfate is some tough stuff. What may work is a noble metal catalyst. Beyond the scope of my ability.

I'd be interested in just how much improvement and for how long afterwards before cliff diving begins, that epsom salts make.

But this info would likely just be used by used car sellers and the like, hoping to not have to put in a new starter battery before sale.

But I guess there are plenty of integrity free, something for nothing folks everywhere, so magnesium salting of rv batteries before sale is not out of the question.
Legion has it used car salesmen use alum in batteries for this reason.

I did build a battery desulfator. Used to to revive several dead batteries.

Large capacitor and rectifier. It works, but not without several risks, including the fact it could kill you.

My dad's service station had a used car dealer next door. First order of the day -- change oil and brake and clutch pedal pads. They washed the engine then sprayed it with clear coat.

Bob Bellemore. A classic. Houndstooth coat, fifty brilliant white teeth a mustache, foot long cigar, and the secret got out. Buy then sell at 200 percent markup.

When something sounds too good to be true -- trust your instincts.

The real "miracle" is the incredible lubricity of them extracting cash from your wallet. Anytime you see print information along with an image of someone shouting the same info in your ear, it's a con job.

If you trust Wiki as a credible source, see:

https://en.wikipedia.org/wiki/Lead%E2%80%93acid_battery

Go straight to the section on "Additives" (near the bottom of the page) if you are easily bored with science, facts, history, and other stuff like that.
