Not exactly, what you say does gradually happen but it is much more complex than that.

Sulphation is non-conductive as is depleted acid (water) epsom salts conduct very well and pass through and into the sulphation allowing the plates to charge (which does cause heat which helps to break up some sulphation), they give up their Sulphur to the battery plate and break away sulphur in the sulphation (depending on if you are charging or discharging)

The magnesium also interacts with "rusted" lead.

Lots of things happen when you add epsom salts and being able to charge is one side effect.

Worth a try as the stuff usually does work but again at a cost. EDTA is better and an EDTA wash is better yet.

Good Luck
