I've watched a couple videos on YouTube of guys draining old batteries and re-filling them with Epsom salt solution.

Anybody done this?

Does it really work?

I got an old Interstate that I'm thinking about experimenting with.

Never heard of it.
Be careful and let us know what you find out.
Also, what would you do with the old battery acid?

Bet it voids any warranty?
But, most likely this is a last resort "solution", and the battery is outside of warranty anyway?

I tried this very recently with the battery from my Honda and it did not work. The charger showed green/100% after about 30-36 hrs and I was all exited. but...No dice, wouldnt even jump start with that battery.

I am not sure if it was my technique or my cheap chinese Harbor Freight charger, but I do know of a place in town here that rebuilds batteies, so I guess it can be done, but not as easily as those videos suggest. ??

You can pour the old acid into a bucket with baking soda and a large amout of water to neautralize/dilute it.

wear old clothes and obviously gloves.

I didnt think I got any on my clothes, but both the old t-shirt and the jeans I was wearing came out of the wash with many holes.

The chemistry doesn't work- - - - -this one sounds like a P.T. Barnum type of sucker bait. Lead, lead dioxide, and sulfuric acid combines to produce a reversible chemical reaction that allows a lead/acid storage battery to discharge and recharge. Adding a foreign substance such as Epsom Salts (magnesium Sulfate) to a battery cannot restore lost capacity.

The chemical reaction in a battery during discharging converts both the negative battery plates (pure lead) and the positive plates (Lead Dioxide) into Lead Sulfate when they react with Sulfuric acid and produce electric current. Recharging reverses the reaction, increasing the strength of the acid and reconverting the plates to their original state. Adding a foreign substance cannot and does not do anything to "restore" a failed cell group.

Batteries fail for two reasons- - - -either the cell plate material becomes dislodged from the plate grids due to vibration and falls to the bottom of the battery where it cannot be part of the charge/discharge chemical reaction, or hard crystals of lead sulfate form on the surface of the plates. Crystalline lead sulfate is almost impossible to re-dissolve by recharging the battery, so that part of the plate group is essentially removed from the charge/discharge cycle. The result is a very low-capacity cell group that has very little reserve capacity or cranking amperage. I can't imagine how adding Magnesium Sulfate would correct either one of these problems.

You can find videos on uTube that show everything from UFOs to Unicorns. You are smart to ask questions before trying it on a good battery. Take anything you read on the 'net with a grain of salt.

UFOs, unicorns? Duh?! How else would they have arrived on Earth?
Sometimes I feel like I have to do all of the thinking around here. Jeesh!

I'm not going to go out of my way to try this. It seems sketchy at best to me.

I was just curious if anyone else had heard of it.

We used to power radios with potatos in science class back in school, so I figure anything is possible.
