The battery trick really works!

by 30 comments
My truck's battery went completely dead about a month ago. I drove it about 30 minutes at 60 MPH to try to recharge it. I went in the grocery store for about 25 minutes, came out and tried to start the truck. Nothing. Not even a click from the starter. The battery was totally dead.

From my research on the web and particularly Youtube, I heard there was a way to "recondition" car batteries. I was skeptical...Nothing could be this easy. BUT IT WORKED!!!!

Here's what I did. I took 8-9 tablespoons of epsom salts. I mixed it with just enough distilled water to create a liquid. The epsom salts dissolves the sulfate that builds up on batteries and causes them to die.

I put 1 tablespoon of the mixture into each of the 6 cells of the battery. I put the battery on a slow trickle charger for a couple of days...(The trickle charger was very weak/slow).

It's been a month since I did this, and the battery is still going strong and starts my truck like a new battery.

Doing a little more research, conditioning batteries like this can give a "4 year" battery a life span of 8-10 years. And adding a little of the mixture about once a year to a good battery can double the cranking amps.

The other possibility for a dead battery is a short in one of the cells, and this method won't work. But if it's sulfate, which is the most likely cause, adding Epsom salts will work.

As expensive as car batteries are, and as bad as they are for the environment, I really hope the next time your battery dies that you give this a try. And don't wait for it to die...When you top off your battery with distilled water, add a little Epsom salts to the water to keep sulfate from building up.

    Ironically, Lead Acid Batteries, are probably among the MOST environmentally safe batteries. The kind used in MOST big vehicles, like motorcycles, cars, trucks, boats, and ships. They are powerful, USED to be maintainable, like yours, and had simple components. ALSO, there is an efficient and well done RECYCLING program! MOST, if not all companies in the US have a refundable "core" charge. You get the charge back when you return the dead battery. And it has been done for DECADES.

    Oh yeah, the biggest waste product from their operation? HYDROGEN!

    Interesting tip Kurt!
    I have never heard of this before, but I have a dead truck battery, and nothing to lose...I'm going to give this a try, revitalizing the cell plates - it makes sense, I don't know why it didn't occur to me before...epsom salts - so simple, it plumb evaded me...

    I wonder what kind of reaction would occur if you put it on standard charge, or if you overcook it ? (luckily for me my charger regulates itself)

    But slower is better. You were smart to trickle charge it.

    Yeah I used to watch my dad fill batteries with water & battery acid when I was a kid, I never understood why he did it until I grew up & got a car of my own.

    Kurt - I had someone tell me once that a crushed aspirin in the terminals would revive a battery as well. What's your take on that one?

    Cool thread, thanks everyone.

    I have two dead batteries I will test this on sometime soon. One is a set of golf cart batteries, the other is a riding lawn mower battery.

    Did anyone else try this yet? It's been about 6 months and my battery is still going strong.

    Again, my battery was not only totally dead, it wouldn't hold a charge at all. 20 cents worth of epsom salts seems to have saved me $75 for a new battery.

    A couple of things - I know it was mentioned earlier in the thread, but a charging battery emits hydrogen. Be SO very careful around the battery when you have it on a charger. Remember the Hindenburg? All it takes is a tiny spark and you have a big TOXIC boom - if the explosion doesn't get you, the airborne sulfuric acid will.

    Second is that you shouldn't charge a battery with the vent caps off. If you're going to replace electrolyte or add water or whatever, do that first and then replace the caps. The vent caps keep the electrolyte from escaping from the cells during charging - and may save a big cleanup job if you happen to tip the battery over at some point.

    Last is that lead-acid batteries DO wear out. You may be able to put off spending the money for a new one for a year or two or three - and that's a good thing - but you WILL be replacing it eventually. The chemical reactions that store and release electricity within the battery also dissolve the lead in the plates, and there's no way to rejuvenate that.

    Hey thats really wonderful trice, hope it would work for my motorcycle.

    Thanks for sharing that. My battery in my truck has been going down lately and I've had to keep putting the charger on it so I could start my truck.

    Will give this a try.

    Thanks for bumping this thread.

    I have a car battery I need to try this on, it cranks slow & has buildup on top of the battery. I never did test this on the golf cart/mower batteries, the cart sold & junked the mower.

    Very interesting indeed! I'm going to get the necessary a.s.a.p.
    Just wondering about the proportions. In other words how much grams of Epsom salt do you think I should combine in a litre of distilled water? Or how much in the case I had to add it directly into the cells? Is there any need to grind it more into a powder to facilitate the dissolving?

    I know that as the plates get heated up through charging, they are slowly damaged. A battery will have less energy each time it is used. So how many times can you do this?

    Some people use alum, some people use epsom salt. Which one works best? Why not refill with regular battery acid?
