I asked my mechanic if they could do it for me. He said yes, but had never seen any positive results.
On the Trojan site I found a video once ( can't find it now ) where the narrator said you could do the same by charging the battery, unplugging the charger and then plugging it in again. Didn't say how long to leave it unplugged, but I suspect maybe 30 seconds so the charger resets.

One battery website had the following procedure for desulfinating a battery: 1) charge battery for 72 hours, 2) let sit for 12 hours, 3) read voltage output. Keep repeating until voltage reading stops improving after each charge/rest cycle. At that point, the battery will be "desulfinated" as good as it's going to get. This all came up when the instructions for a charger splitter I purchased for charging two batteries at the same time said the two batteries had to be at the same level of desulfination for it to work properly, but the instructions did not indicate how in the world to determine that. Still not sure how to compare the level of desufination of two batteries other than if they have the same voltage output they might be similar enough in desulfination. Any ideas?

Since the individual cells within a single battery won't be in exactly the same state, I doubt there's a good way to establish anything definitive about the "sulfinated" condition for a battery.

Years ago, I worked with an engineer who had done it himself several times... This was back in the seventies when "Lead Acid" was pretty much it. I will warn you though, if you attempt it you will be buying a new wardrobe of work clothes no matter how careful you think you are! As explained by my mentor back in the day, sulphur deposits and other contaminants collect in the acid solution at the bottom of the cells. This build up of deposits is harmless at first, but becomes a high resistance current bleed into adjacent cells until the cells effectively die. If the structural components of the battery including the lead plates are intact, then the batteries can be emptied, flushed out, re-filled, and re-charged... Easier said then done. If you make it this far, you have two problems... First - what to do with the acid and goop that was remove/flushed from the battery and Second - where do I source the correct solution and strength of Acid to re-fill the batteries... This is where I lost interest back in the day and saved my money for purchasing new batteries. I will tell you though, it did work and the batteries behaved like new ones.

While I like the idea of fixing things rather than throwing them away, I think in the case of acid-filled batteries it's probably a better idea to let a battery factory do a more thorough version of the same thing: recycle the failed battery into a new one! But the flush-and-refill method does make sense; I'm sure it would work for many batteries.

The pulsed desulfation mode that some newer chargers have does seem to work. They do a smarter and more automated version of the unplug/replug thing, pulsing a higher voltage charge then dropping back down. I've personally had some luck with the Schumacher one on car batteries. Much less messy than opening it up and physically removing the crystals, and no worries about getting the acid content just right.
