How much old used battery acid do you mix with a concentrated Epsom salt solution. What proportions? Also , once the battery is restored do you leave the Epsom salts and battery solution in the battery and continue to use it like that or does one discard that mixture once battery is fully charged and refill the battery with fresh clean acid?

epsomes salt / distilled water and leave off the caps while you recharge. 15 minutes on 200 amp start position on charger. Stop for 1 hour, charge for 15 minutes, stop one hour, this is done 5 times. The battery will be like new and last for years with only the recharging for 15 minute intervals.

[@MikkoRantalainen]

The true test is fully charging those batteries, then run them each with e.g. 20 A load (e.g. 4 headlight bulbs in parallel) until the voltage gets down to 11.0 V. You can then compute the total energy released to figure out how much capacity you end up with (basically the longer it takes the better the battery is). Simply being able to load the battery to correct voltage doesn't mean that you can do anything meaningful with the battery. A good car battery is rated between 50-120 Ah as new and if your reconditioned car battery has 2 Ah, it's practically not usable for anything even if it technically still works as perfectly good 2 Ah battery. If you truly just need 2 Ah battery, you should use NiMH or Li-on batteries instead.

[@MikkoRantalainen]

@@christianpowerssavesthewor8404 The 12.58 V that you measured is voltage. When you run the starter you need power and for that you need current. The power is literally current multiplied by voltage. The problem is that when battery is bad, the voltage drops rapidly when you try to drain practically any current. A simple test is to measure your battery voltage like you did and then turn on the headlights and turn the ignition to "ON" but not try starting the car. Then measure the battery voltage once per minute. The current needed for the headlights should cause less than 0.01 V drop per minute (but the drop from 12.58 V in this example to headlights on state could be e.g. 0.3 V even with fully functioning battery). The reason for this is that the total energy stored by the battery is limited by the lead surface touching the electrolyte. With damaged battery needing reconditioning the lead surface is damaged and cannot react with the electrolyte over (large?) designed areas. As a result, you get expected voltage but the total energy is very low so draining any current will drain the energy fast out of the battery. Again, energy is literally power multiplied by time. So the above test with headlights on is actually draining energy from the battery and the voltage drop is used as a proxy to estimate the remaining energy in the battery. You can imagine 12.7 V meaning "100%" and about 10.7 V meaning "0%".

[@Brooslinks]

@@MikkoRantalainen Thank you for the explanation, I didn't know when he use the boil distill water because it looks to me he still refill the batteries with the same electrolyte removed from them.

[@MikkoRantalainen]

@@Brooslinks Oh, you do need to add any lost water but also the part of the lead surfaces that's always submerged get damaged over time. And all the damage there cannot be recovered, no matter what you do and that's the part of the damage I meant above. The parts that are not submerged obviously do nothing for the energy storage so you always want max amount of distilled water in a lead battery.

[@brianlitecky9798]

[@MikkoRantalainen]

@@brianlitecky9798 Definitely. Lead batteries were invented around 1859 and the only thing that has changed is purity of the materials used. The less contamination you have, the longer the battery can live. Of course, the body of the battery is nowadays plastic instead of glass for obvious reasons.

So many of us who owns cars, trucks, motorcycles, etc., for transportation, always thinks that when batteries goes dead, you must always spend more money again to but a new one. I've revived two very old batteries that were dead, by just hooking a 20 watt solar panel directly to them without a solar panel controller. And BOOM! Batteries still works, installed, and started a Dodge Caravan. And the other one is a backup. Someday I'll try your trick, and let you know how it works out!

[@hom240]

The coating in the battery is sulfur oxide. The metal looking debris is mostly lead and some of the steel grid that is imbedded in the lead plate to hold it all together. The Epson salt trick works 1 time. It somewhat removes the sulfur oxide, but over time will deposit magnesium into the plate.

[@CarGroves]

If it works, it works.

[@MechanicalMafioso]

At either rate, the batteries are worthless to begin with, so if it’ll buy a even another year or two. That’s still a win win…

[@daviddawson6394]

Hi all. I'm a mechanic of 27 years. Not everything in this video is correct. If you have an old battery, I can give some simple advice. ( But be assured, the battery will never be like new). You MUST use a "load tester" first, to document the condition of the battery. NOT a Multi Meter, but a LOAD TESTER, that you dial the correct CCA (Cold Cranking Amps) value of the battery as displayed on the label. Once you document the poor condition of the batter, now it's time to recondition it. 1) remove car battery and place is on soft ground such as your lawn. DO NOT open caps or remove any acid yet. 2) Roll the battery around over and over for several minutes. use your boot and kick the battery and make it tumble for a few minutes (this rough contact breaks a lot of the buildup stuck to the plates). 3) Drain all the liquid into a container holding the battery upside down to drain it all. Keep this acid and allow the dirty looking liquid to settle over a few hours, This will take time until the sediments settles to the bottom of your bucket. 4) fill battery with water and repeat process of rolling it after putting caps back on, but DO NOT keep this liquid! instead, dispose of this waste. 5) Once battery is empty again and the captured Acid part 3 has settled and looks clear, carefully pour the acid into another container, leaving lead sludge behind. Finally top up the batter with the clean acid and test the battery on a "load tester".. Yes you can charge it, but prior to doing so, test to see if there is improvement. I recently done this to a Pajero V6 Petrol, that had a dead battery. The Battery bounced back and I got 6 healthy months from it, but eventually it failed to hold a charge. No Epsom salts used in this process, however I am sure that will only improve the condition to perhaps give you as much as 12 months of life out of it, but I cannot verify that as I haven't used salts.

[@Budl1te]

You are correct, The trick is to get the stuff at the bottom broken up and out of the battery. That alone (if it causes bridging) can cause the load tester to give a thumbs down so I am not sure what you would gain by using the load tester first. I am not an expert by any means!

[@Blaaggarding]

Your a mechanic you know well you should just change the battery come on for god sake all that pissing around and then the thing leaves you down at the worst possible moment. If you have got time to this and earn a living repairing vehicles I tip my hat to you sir. 👍

[@daviddawson6394]

@@Blaaggarding this information is valuable and important to know and I'll give you an example. I was working as the mechanic on a remote stretch of hi way on the Nullarbor in Australia. Known as the worlds longest straight stretch of road. This road consumes many cars that were not prepared for the drive, and "the Car Graveyard" located 2km from where I was working, was full of perfectly good cars, with damaged engines. One day a Toyota 4X4 with a flat battery that couldn't be charged broke down nearby. The two young backpackers driving it was freaking out as they needed to get back to Perth to fly home in 5 days, Yet where we are, it will take a week to have a replacement battery sent in. This is when that knowledge is valuable as I did it to their car battery and got them to a point where they could start the car with ease each time, and keep going to complete their last 1400km journey. I certainly do not advice you do this trick to a dead battery and then rely on it like these people did to cross central Australia through the desert. But for their needs and the fact they had little option, it worked 100%. But you are correct, ALWAYS replace the battery and be done with it. Peace of mind is important.. Women will NEVER be comfortable with a quick fix like this. They freakout at the very idea that their could still break down. Men, love the challenge hahahaha

[@danielmorrison7579]

Your voltage reading means nothing until you put a load to the battery. Load testing is the only way to get a true value of the state of a battery.

[@achristian7015]

At the beginning of the video when you talked about voltages, a 10.8V battery is a totally dead battery. A fully charged Flooded Lead Acid (FLA) battery reads above 12.6V...sometimes 0.1 or 0.2V higher. And a voltage test indicates the state of charge of a battery but not its health. You need to do a load test and a capacity test, the latter is time consuming and you need to use specialized equipment. Its all fun though.

[@lobdsk]

@@ibberman I get it from NAPA

[@jimhofoss9982]

sulphation is the killer, sediment settles to the bottom and shorts out the cells. After bathing the batteries in epson salts( for an extended period), and a thorough flush, use distilled water, and proper amount of sulfuric acid to fill the cells. Don’t use the old electrolyte! You won’t be able to remove all the sulfation between the lead plates, but some more limited service of these used batteries is possible. The capacity and cranking amps will still be compromised. Worthwhile to do IF the batteries were not frozen when discharged, and no bulging or distortion of the lead plates is visible. cheers!

[@CarGroves]

Obviously new acid would be ideal. I was just showing how to do it the cheapest way possible. Thanks for watching!

[@Swansen03]

right, of all the assholes in the comments at least one person was able to be objective. if the plates can be cleared and new clean solution added some service can be restored. in my mind, i think this process in combination with a large capacitor for extra cranking capacity is a pretty good solution.(then once failure takes place, find more dead batteries, rinse/repeat but obviously the capacitor would still be good)

[@babelonchabalala1690]

As mechanic i was sceptic about this but i tried the baking soda method yesterday, (without the epsom salt at all) ..... firsy i drained the battery of fluids, added baking soda( or known as Bicarbonate soda) with normal tap water ....let it sit for about 2 hours, shaking it every half hour until the bubbling stops.....then rinsed it with tap water again..... added baking soda again and let it bubble again till it stops.... then sinsed with tapwater again until water comes out clean..... then added fresh distilled water and then fresh battery acid (all for $5) ..... i put it on the charger for about 5 hours.... the next day car cranked slow but started..... i drove around a bit ..... after that car started everytime on the first crank.....before this starter motor didnt even make a click noise thats how bad the battery was....now it starts like a new battery..... my conclusion is that the baking soda method works, and you must add fresh battery acid and distilled water.......my other conclusion is that the alternator charges differently than a house car charger, even better..... i think its about the Amp output of alternator thats higher i dont know but after driving around the battery improved its charge cycle ..... glad i tried this coz it saved me $150 for a new battery lol.... at least i can start saving up for a new battery while the restored one keeps me going 🥰

They would do a couple dozen a day between the 2 shop hands. Safety wasn't as big of a deal back then though and my dad had one explode in his face that was overcharging and starting to boil out the caps. By the time the owner yelled out to him to stay back he already was sprayed with hot acid. It managed to build enough pressure to blow the seal for the top and send the top flying. Luckily he just had minor scarring, his sight was affected later in life though. He still has visible scarring when looked at in the optometrists images after his last laser eye surgery, which made his 3rd to try to correct it.

Getting a battery to come back is very tricky. I have the top of the line charger from Harbor Freight. To see if a battery is doable, do this: Top all the ports off. Maintenance free is still toppable. Most of the time the cells are low. After 10 minutes of charging in AGM mode, do this test. (AGM mode with remove a short off a cell most of the time.) Take a multimeter, go to +, and read each cell with the probe tip stuck in the acid working towards -. If you get at least 1.8 volts difference between each cell, it's doable. Charge at 8/10 amps standard battery mode for 8 hours. Load test the battery. If it dies quickly, drain the battery & add fresh acid. Can be purchased at an auto parts store. Recharge the battery again. It should come fully back & hold a charge. I didn't add epsom salts or cadium tablets & had success.

Voltage is one thing but current delivery is another. The amount of amp hours and cranking amps can't be measured with a multimeter and I doubt they would last in operation. Sulphated plates cannot be physically cleaned this way as the plate separators are compressed with the swelling of sulphation, jamming the lead sulphate in place. A tell tale of these un recoverable dead batteries is the bulging of the case, especially at the ends. The epsom salts may clear around the edges of the plates, but you'd be very lucky to get even 10% back.

[@alasdair4161]

@@CarGroves two ways they can recondition them, one is to do production line impedance and load test and reject below a certain capacity, the other is to cut around the case just below the seam, lift out the plate assemblies, pressure blast the cell clusters and clean out the sediment cavity then reassemble, ultrasonic welding the plastic back together and adding new acid before charging. Again, they would be graded before reconditioning and any falling below the standard just get recycled. Car batteries are 99.9% recyclable, so they can't lose either way.

[@coolvidz1763]

my take is that you didn't clean the plates with the rinse or the epsom , but with the initial 50A charge. Sulfates are stuck on the plates and you'll need high amps to dissolve those precipitated placks on the plates. Usually a good 10-20 minutes on a 100-200A charge until you see bubbles coming out of the cells will recondition your batteries . I wouldn't advise playing around with highly concentrated sulphuric acid. It's extremely corrosive and dangerous if it gets on the skin , it literally slowly burns away any fabric.

Hello Karen

[@bobbiegorham4782]

I watched a video right before I found yours about saving an old battery and the only thing different in the other video was the old guy first charged the old battery as much as it would take, drained the old liquid, and used a solution of baking soda and reagular tap water (10 ounces to 1 gallon) and it bubbled and hissed totally cleaning most of the build-up out of the old battery. He only used 12 ounces of Epsom salt in a gallon of distilled water for the new battery fluid. I don't know if that makes a difference but it seems the whole bag would probably work a lot better than just 12 oz. I figured I would let you know his trick for cleaning out the old gunk it seemed to work really good but be careful because when you add the baking soda/tap water it will cause a reaction and spit and spew pretty good, saftey glassed a must, I'm going to use a 6ft hose so I'm not close to it at all when it starts spitting.

Battery minimum voltage should be 12.5. They should also be load tested. Hate to be negative, but there is many ways that a battery can fail. As a battery ages the lead decomposes and ends up in the bottom. It belongs on the plates. Even if one can bring it back to life it will usually have low cranking amps or test amps. If the battery gets discharged too many times it can also sulfate.

[@steggc85]

K Kenason absolutely! 13.5 is the optimal voltage

[@kkenason8728]

12.5 volts is the Minimum voltage if the battery is sitting not connected to a charger. It is a static rest voltage.

You’re lucky you can still do that in the USA. Here in the UK all batteries are sealed now. But you’re missing a trick by not settling and then filtering the old battery acid. If you filter the settled acid first through a very fine tea strainer to remove the larger particulate matter, then through coffee filters, you will have a far more extensive process, and end up with a much cleaner, more efficient and longer lasting acid. It’s those floating particles which have come off the plates, that cause the drop in efficiency in batteries.

[@CarGroves]

Metal doesn't float in acid

[@G58]

Car Groves that is of course true. But I’m not talking about metal - as you should already be aware. The corrosion or scale on the lead is correctly termed sulphate. As I believe we have both figured out, it’s this sulphate material that’s clogging up the battery, shorting out the cells and causing it to become inefficient. So it’s the sulphate that’s floating about, not metal. Try thinking before typing a comment based upon assumption and insufficient knowledge. Many of the so-called ‘haters’ on here are actually sharing accurate information. I’m one of them.

The battery I have all the cells had very dark H2SO4 electrolyte fluid from dissolved plates. Flushed and filled with baking soda then drained flushed and replaced with distilled water and Epson salts. Tried to boost with 55 amps to activate the cells for 15 minutes and let it rest for an hour 5 times. Then charged with a smart charger overnight. made absolutely no difference. These techniques only seem to work with batteries that are weak but not with bad plates like mine. It was not keep up with a smart charger every time which might have killed it. If the charge becomes very low the plates seem to dissolve. I have two other batteries that are over 10-15 years old and they are still 100%. Kept them up with smart chargers whenever they got low so the de-sulfating setting could work well.

In my case I have a 12 volt 7.2 Ah battery that although the voltage was at 12 volt when it shorted it did nothing. With the distilled water method it improved a lot only that instead of 7.2 Ah it has 5 amperes, with a no-load voltage of 12.40 volt after a week it remains at 12.00

[@dukecraig2402]

@@enzovideogames 12v indicated with a volt meter is actually considered less than 6% charged. What most people don't understand, and apparently includes the guy who made this video, is that the percentage of charge for a lead cell automotive/motorcycle battery isn't 100% at 12v and around 10% at 1v, it doesn't work that way. A battery that shows 12.66v with a hand held volt/ohm meter (VOM) is considered 100% charged. A battery that shows 11.89v with a VOM is considered 0% charged. It doesn't work the way that your common sense tells you it will, the percentage of charge doesn't go from 0v indicating 0% charge to 12v indicating a 100% charge. It actually goes from 11.89v considered 0% charge to 12.66v considered 100% charge, 12.24v is actually considered to be only 50% charged, it's not the same as the battery in a cell phone or a laptop, the difference between 0% and 100% charge with lead cell automotive batteries is completely different then a cell phone or a laptop going from 0% to 100%, this is the mistake people make when evaluating the charge condition of a car battery, they compare it in their mind to how their cell phone works but it's completely different. And then you have a load test that simulates cranking on your starter, a car battery can indicate 100% charge, which is 12.66v using a VOM like he is in this video, but you hit the button on a load tester type battery meter and watch the needle dive down into the yellow or red zone on the scale, which means that even though with a VOM it's showing 100% charge it won't pass the load test (which simulates cranking on the starter). Then you have whether or not a battery will hold it's charge after sitting overnight or a few days, you can charge a battery to where it shows 12.66v with a VOM which is 100% charge and leave it sit for 2 days and then put a VOM on it and it'll indicate 12.24v which is 50% charge, meaning that it lost half it's charge sitting for 2 days. It's far more complicated than this guy leads on to be, the only way to properly test an automotive/motorcycle battery is to charge it to where it indicates 100% charge (12.66v) and then hit it with a load tester for 10 seconds and see if the needle stays in the green zone (acceptable) on the scale or drops down into the yellow (meaning weak) zone on the scale or into the red zone of the scale (meaning bad). Hand held VOM meters only tell part of the story, and can't properly evaluate that type of battery, auto parts stores like Autozone usually have a hand held load tester and will gladly walk outside to your car with it and load test the battery for you.

To really test the quality of your battery rebuild process, charge the car battery at 2 amps for 48 hours. then let the battery sit for 2 days and measure the voltage. It should be around 12.5 volts. Then try starting a car and make note of the sound of the starter speed. Compare that to the sound of a good battery when cranking the same car. A better test would be to take the battery to a auto parts store and have them do a discharge test. Car batteries will provide upwards of 90 amps under load. Batteries fail due to increased internal resistance limiting that maximum current under load. So voltage alone is not a good indicator of the quality of a battery.

Put it back together, add new electrolyte and charge it up. At this point you will have wasted more money and time than buying a new battery.

There is an easier method that only requires 15 minutes of 200 cranking amps 5 times, let the battery sit for an hour in between each 15 minutes, it boils all the crap off the inside of the battery and brings it back to life.

[@Devoneakapimp]

1000% correct. Only if people knew

[@johnboysautobody4214]

What?

[@PIAZI123]

WTF?

[@ChrisLesmerises]

This won't remove the contaminants. It's more akin to acid dipping a rusty frame, and letting it sit in it's own oxide juices so they can recombine again. Let your acid cold settle, then decant and filter your acid solution.

Maybe not wear flip flops

This is good to know bc alot of men would t help there significant others help with there vehicles thanks so much

Ill give you a hand lady

[@suspectalien246]

This article is completely misleading he might have brought the voltage up did you see him try to start a vehicle?no you didn't because they won't they don't have any power in them a battery that reads 12v is practically still flat 12v lead acid batteries charged up will read 13/13.5 or even higher up to 14.4

[@CarGroves]

Ever seen one read 14.5?

[@suspectalien246]

@@CarGroves yes I've seen them hit 18/20but your overcharging and your damageing the battery

[@timedwards752]

Anything over 13.8 is damaging the battery.

[@davidreynolds4684]

Im hoping youll do a follow up video showing if all of the batteries took a full charge and held it. Good video

[@randellgribben9772]

never did...

[@VirantRoss]

*Did I miss the part on the ratios of the sulphuric acid & Epsom salt mixture ratios???? Neither works alone? It must be mixed??* 🤔

[@VirantRoss]

I feel he failed to show us the MOST IMPORTANT part, of making the new Epsom & Acid mixture being put into the battery... Youd think thats most important piece of info in this process! 90% of the video is him draining/emptying the batteries & charging.

[@CarGroves]

Watch video 2

[@brainwashed7244]

Static charge I want to see a load test please

[@CarGroves]

You can static charge your finger by wearing socks on carpet. Thanks for watching.

[@mtay65]

tell us CCA of each battery after charging....getting 12V doesn't mean anything

[@CarGroves]

I'll do a second video soon with CCA

[@ThePreyMantas]

@Brunz M That would be nice to see befores and afters. You'd think that folks would be aware of that since that's what it's all about. ;)

Had a Sears battery that being about a month old died in the middle of a crank. Full voltage yet no amperage would not even activate the solenoid. Took back to Sears told the guy what it did, he put on test bench put big leads on to it. Tested acid with hygrometer- all even- full charge. He hit the amps test and the needle hardly flinched. Threw it in the pile wrote me up for another.

[@jimquantic]

No, it means SOMETHING, but..I know what you mean. And even the 12V, we need to know if it HELD that 12V.

[@MrPhatties]

You can filter the acid you removed through a coffee filter to clean it up before putting it back in.
