How do desulfate batteries - [1]
Hydrometer measures specific gravity of electrolyte - [2]
Questions - how to knock off sulfate and replace battery acid?
Specific gravity of bat acid - [3]
Throw powder down each battery - is this just a base to react with sulfate? [4]
Use a battery load tester to test if battery is back up
Looks like a good instructional on Epsom salt method - [5]. Magnesium reacts with the lead sulphate, nonconductive crystals go away. The thing I don't understand - if the battery reaction involves sulfation - when does sulfation become irreversible? Only when too much sulfation happened, ie, you drained the bat too deep, and you can't get to the underlying metal?

Use epsom salt - mgso4 - [6]. This is great series - [7]. Half cup of epsom salt with water.
- Showed 3 mOhm resistance across 12v bat.
Instructional on using epsom salt to dissolve sulfate - [8]
