I worked in a chemical laboratory where each winter one guy would bring in his car battery , empty it , flush it out with water, rinse it with distilled water and put new mixed battery acid back in. We used to mix battery acid for replacing it in fork lift trucks on the plant. He said his battery was now 20 years old and he did this every year just before winter. The sulphate (black) that gathers on the plates falls to the bottom forms a sediment and can build up to short out a cell. You need to get that black crystals out. Clean it with a water jet several times until no more comes out. New acid and off you go again. Try and avoid other chemicals.

Battery acid is just so expensive... where do you get it cheaper? Cheapest I can find is $20 for 64oz. How much does a 6v flooded golf cart battery hold? I'd like to change mine out also. I was going to do the old welder trick and dump/replace... or dump and put in new... thoughts?
@@dustins4194 Battery acid in the laboratory was easy, as we used to mix it for the Fork lift trucks on the chemical plant warehouse. I actually tried the old welder trick this year as I had a big battery which had a weak cell. However that just completely wrecked the weak cell.
The best way is to just empty the battery and hose it out to remove the sulphate sediment which can build up in the bottom and short out the plates. Then refill with new acid you can buy from battery suppliers. 64oz would be way too much I think. Flush and refill is probably best.
@@awalk5177 the videos using just 35-50 amps looked promising. Don't arc it too badly inside and just heat it all up. Then shake it, dump it, clean it out, and refill it... that was my thought anyway.
@@awalk5177 do you remember the mix to make it? Buying it is pricey
You might want to try skipping the baking soda wash out. Any residual will kill the new acid.
Yeah, I'm no expert but the most I'd do is rinse it out with distilled water.
Epson salt don't work either
I followed your instructions just now 3/6/23. I added EDTA with baking soda. Flushed till clear, filled with electrolyte solution and they are perfect without charging.
Same here .voltage went up on it's own
Good Video. Honest fellow. I have tried different ways myself over the years and never revived one battery. Found it to be a waste of my time yet I watch these videos hoping someone actually restored a battery back to like new condition. Once again this is a good video from a honest person with honest answers.
I have spent months researching into battery repairing and found a great website at Magic Mender Wizard (check it out on google)
The best thing I've found is that when you can convert a weak battery to alum and use it to run camp lights and stuff. I don't think you can really restore a weak battery to a state where it would be good for starting a car. Especially in cold weather. The one thing you can try is overcharging and discharging the battery (to 11 volts) about 5 or 6 times. This has been known to sometimes give a weak battery a little more life, but no miracle restoration. Real restoration typically involves tearing the battery apart and replacing bad plates. Dangerous and unhealthy work.
@@donnybowers7832 my Grandpa worked in a battery manufacturing plant in southern industrial California,he worked with all those cancerous metals which are now banned..
He ended up with Cancer while still handling it..his health deteriorated quickly and also went home contaminated and transferred it to all the furniture in the house and ultimately and unfortunately his wife also through years of exposure,she also ended up with Cancer..
Grandpa was only in his early 60s.. Grandma lost her battle years later..
Be very careful around opened Car batteries,it's not just the liquid part but also the fumes can accumulate in your organs..eyes, lungs, you breath it and swallow your saliva and on..
yip, my experience was exactly the same, came to see how you fared :) did save 2 drycells with rinse and new acid pour. all the car /ldv batteries i have tried was a waste of time, but i still enjoyed trying.. tks Bob.
First of all, I'm glad your wore those rubber gloves. Blisters from acid burn make it near impossible to play the guitar. I'd like to thank you also for doing this so I wouldn't throw $13.00 into my battery and maybe get the same result. Mines been sittin dead for almost a year and a half. Great video.
I hear a secret they don't want you to know. You need a 200 amp charger 15 minute intervals 5 times resting 1 hour after each 200 amp blast takes about 5 hours, but at the 5th blast all the cells will read good on the electrolytes, but check gravity first you'll see 0 or very close, but after the 5 cycles it will restore the battery then trickle 3 amps until it is complete
The problem you are having is caused from using baking soda to clean the battery.
Baking Soda is an alkaline and will neutralize acid. If you don't get all the Baking Soda out it will destroy the acid. All you need to do is fill the battery with plain water, shake it around a few times; do this as least two times. The water will flush out any loose lead Particles that may be shorting out the battery. Pour out the water and fill with new battery acid. It worked so well for me that I didn't even need to charge the battery.
thanks so much.
It's not lead particles, it's sulfur (sulfuric acid), that's why it is called sulfation! The act of electrolysis causes the sulfur to form a film on the lead plates which reduce their conductivity. The whole object of reconditioning a battery, is to get the sulfur to leave the surface of the plates and re-suspend in the electrolyte.
@@Rattlerjake1 nope. lead sulfate.
@@thedavesofourlives1 - Try reading what sulfate is! Sulfation is the salts from the sulfuric acid. When I said it is the sulfur, I should have specified it is the salts. Lead doesn't have salts. So to be specific - lead sulfate is nothing more than the salts from the sulfuric acid forming on the lead.
"The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO²⁻ ₄. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid."
Curious. How about distilled water to wash it out ?
I always find car batteries next to dumpsters at apartment complex buildings. I guess people don't hassle with dying batteries. I've found a couple of good ones that just needed a little acid and a charge.
I charge batteries all the time, but when one goes dead I usually have to charge it for 3-5 days to have a good charge, and I use a hydrometer to check the charge of each cell, also with a hydrometer you will know when you have a bad cell.

I tried that with my 200 amp booster charger on 4 different batteries. No luck.
@@glenchadwick420 really, I seen a video but I believe once you dissolve the build up plates and replenish with electrolytes, unless mechanically damage should work, but best substance for cleaning the plates idk
hi everyone ,if anyone else is searching for reconditioning nicad batteries try Jons Mender Guide (should be on google have a look ) ? Ive heard some decent things about it and my friend got amazing results with it.
True i use a 40 amp charger and let it slowly charge goes well too
How much does a 6v flooded golf cart battery hold? I'd like to change my acid out also. I was going to do the old welder trick and dump/filter/replace... or dump and put in new... thoughts?
I did not clean out my battery I just dumped it out then put in new acid and tested it right away and it was 11.5 v but it took about a day to get my 100% charge
Reconditioning method depends on cause of battery failure. But for simply flush, you should empty old acid, put in emsom salt+distilled water solution, then charge it. Then empty it out once again and then add the battery acid.
Does this work?
Unless U check cell by cell wid a meter or wid a hydrometer, Ur not going to de specific 'heavily sulfated ' cell or kno if it's completely deterioted n jus get anodda new one. There is a reason batteries has a self life cos de plates r thinner (cheaper $$) and completely breaks apart.
The bubbling you see from adding the Sodium bicarbonate, a salt (a base chemical) is because it is reacting with and neutralizing the sulfuric acid that was first in there.
There is no "cleaning" action as it has nothing to do with buildup of (sulfur?) crystals on the plates.
I don't understand why people think baking soda will help. The best way to break up sulfation is to overcharge and then discharge up to 5 or 6 times. There are some devices that claim to desulphate while charging. My understanding is that they work, but only to a point. The cheap ones would take months (maybe years) to desulphate a badly sulphated battery. In any case you'll never restore a battery to anything like a new battery.
I believe the baking soda breaks up the sulfur buildup @@donnybowers7832
With them batteries you have to keep cleaning till clear liquid comes out and also before emptying all the way turn on the sides and tap it against the ground a bit
😂 "Again, wear rubber gloves like I am" (shows his hands with no gloves on camera) 🤣
Great video. Thank you for sharing
The only thing I've see work somewhat for trying to bring a battery back for use in a vehicle is using a dumb charger to try to break up the sulfation on the plates. It usually involves overcharging (24 hour low amp charge) and discharging 4 or 5 times. A typical charger won't work well for this. You need an old fashioned dumb charger that doesn't stop charging when the battery is fully charged, and you have to monitor the battery to make sure it doesn't boil over or overheat.
There is a type of battery restoration that I use all the time that has maybe a 75% success rate. But it involves converting the battery from acid to alum electrolyte, and it's not a good idea to use them in your car, truck, tractor etc. They can be very powerful batteries and you don't have to worry about how low you drain them like you do with the acid. But, the voltage will be lower than a regular lead acid battery. A good one will usually hold about 11.5 volts (you really should use an 11.1 volt solar charger to charge it rather than a regular 12 volt). If you convert one and it only holds about 9 or 10 volts you have a bad cell and you shouldn't use it for high amperage circuits, but you could still use it to run maybe up to an amp or two. The reason being that the dead cell will heat up and boil off the electrolyte. You especially don't want to charge it with more than an amp or two.
I would say the reason your battery will only hold about 9 volts now is because you probably have a shorted cell and maybe another one that's starting to deteriorate or just a lot of sulfation. You could drain the acid and replace it with alum water (about 1 1/2 cups to 3/4 gallon of water), but don't expect a car battery. You could use it to run a low amp 9 volt circuit. I've even run 12 volt - 3 to 5 watt camp lights on them because the lights I use will continue to work down to about 8 or 8 1/2 volts. I have one I've been using for about 3 years to run one of those little ten dollar 9 volt "Mighty Lights" (as seen on TV) that has a motion sensor and a dusk to dawn photo switch built in. I use two 9 volt hobby solar cells from Radio Shack to keep the battery charged up to 9 volts. It actually works great with very low maintainance. And the nice thing is that you can discharge it as low as you want and it won't damage the battery like with lead acid, which will begin to cause damage as soon as it gets below about 11 volts. Some say 12 volts.
Isn't all that messing with the electrolyte just as likely to stir up the sulfate sludge from the bottom of the case and short out the plates?
@@michaelcyr8215 Yes. That definitely can happen. Typically you try to rinse as much of that sludge out of the battery as you can, but I have had batteries that developed a short most likely caused by sludge or debris bridging two cells. It doesn't happen all the time, but it does happen. Again this is probably not a good way to try to restore a battery to start a vehicle with, though if you get lucky and get a good one it will start a vehicle. Obviously the dirtier and more eroded the plates are the more chance you'll have of failure.
Nice video, thanks. I like the idea better than the Epsom Salt idea. One thought: After emptying out the bi-carb solution and before putting in battery acid, perhaps a soak with just distilled water would help. Any residual bi-carb will probably not make a huge difference, but every little bit counts when trying to save an old battery. Sorry it didn't work out for you.
thank you.
yep I think a good flush out before adding the electrolyte may help. good video
Since the fresh battery acid didn't do the job, how did adding epson salt to the fresh acid work? (I didn't see a video from you on that... sorry if I missed it.)
I know this might be a stupid idea but after flushing the battery out a couple times with the baking soda water, what about sticking a pressure washer nozzle in the holes and physically blast all the sulphur crystals off the plates and then add your Epsom salt water/battery acid?
That will wreck the plates & separators (which probably weren't healthy to begin with), effectively killing the battery.
@@videopipeline6419 I see. Thanks!
You don't want to pressure wash the inside of a car battery, you might destroy what is left of the plate separators.then you will for sure have a Battery that cannot be reconditioned.. just rinse it out with a garden hose repeatedly until it flushes out clear.,then maybe a few baking soda treatments with battery shakes and tumble after the gases settle..final rinse and shake with distilled water..
Now check out each cell bank for voltage increments from the negative to the last one next to the positive post..any deviation drop in voltage as you get close to the positive post ,will most likely dictate that the battery is having plates issues and maybe not a good candidate for saving or spending any more time and money on it..
Was about to try pouring new acid. But thanks a lot for this video I don’t need to do it anymore.
Honestly it was a very bad idea to put baking soda inside the battery and that very well could be why his attempt at refurbishing the batteries failed. Car batteries require acid in order to hold a charge, and baking soda neutralizes acid. Unless he got 100% of the baking soda out of the battery, which I doubt he did, the left over baking soda reduced the acidity of the electrolyte solution and further impaired the battery's ability to accept a charge.
@@AllPainNoGains This and most other videos like this start out by dumping the existing electrolyte in an attempt to remove the "plate shed" (see below) that accumulates in the bottom of the battery. But just like it's impossible to dump out all the electrolyte, I think that inverting and shaking a flooded battery tends to cause some of those byproducts to get stuck in the plates, making the problem worse. After I did this to a battery that apparently had one dead cell, the voltage dropped further, indicating it now had three dead cells.
* from Battery University BU-804a Corrosion, Shedding and Internal Short: "As the battery sheds its lead to the bottom of the container, a conductive layer forms that gradually fills the allotted space in the sediment trap. In time, the now conductive liquid may reach the plates, creating a shorting effect. The term “short” is a misnomer and elevated self-discharge or soft short would be better terms to describe this condition. Soft shorts are difficult to detect because the battery functions normally immediately after charge and everything seems fine. In essence, a charge wipes out all evidence of a soft short condition, except perhaps an elevated temperature during charge that may be noticed when touching the battery housing. However, once rested for 6-12 hours, the battery begins to show anomalies such as a lower open circuit voltage and reduced specific gravity."
It is 65% distilled water and 35% sulfuric acid, unless it says ready to use electrolyte. If the plates inside the battery has lead sulphate buildup on them then changing solutions is not going to work because the electron flow in being blocked by the lead sulphate buildup.
Change the plates or try to find a way to clean up the lead sulphate buildup.
After equalising an old depleted battery wid an ok battery brings up old battery to allow normal battery 'trickle charge' charger to work. Need to check battery acid levels r topped, leave caps off and charge it for 24hrs min. Another thorough step before dis can be to 1) empty old battery of acid and store for later use 2) fill battery wid warmed up mixed Epsom salts and shake it a bit den charge it.
3) empty all water /Epson salt and flush again wid more distilled water. 4) fill back old battery acid (sulphuric acid)/ filter over an old cotton to rid of residue metals, dirt.
5) cycle charge wid high amps (above 16.5amps or some use a adjustable amps welder) for 5mins (till solution bubbles) rest for 30-45mins. Repeat this X3. Check voltage n amps, if load meter is gud disconnect and check again next day. If it hold, den U hav revived a sulfated battery. Some times U might need to add more battery acid if hydrometer shows ratio is light ( not concentrate enuf).
well, you are honest. I tried this and the 200 amp method, neither worked for me.
Other tuber put them on trickle charger 1 amp for 4 days. What was the water to acid ratio you used?
good video, how much acid into an average size battery/
Remember to used only distilled water, caused pipe water contian chorine. You can however get the water that being filtered with a carbon base, these take out the chlorine to some extend. Boiled the water after leaving it to cool will also help. But the same battery may not be washed with soda more than once or twice, the soda will kill off the plates inside the battery.
Thanks for trying, and showing us your result!
Was the sulfuric acid you bought pre diluted or did you have to thin it with distilled water. I know with new motorcycle batteries the fluid is allready mixed at the proper ratio. Other times ive bought 5 gal sulfuric acid and it was near pure and had to be diluted.
Don't know where he got what he got. I usually buy pre-diluted electrolyte from oreily's. Pretty simple to work with
Due to the inability to reach all the areas soda Invades inside , will still be there.
A water pressure in-FLUSH-OUT is needed to get it out.
The loose Plate material scale-particles cause lots of short out "parasitic voltage losses" making the battery appear bad when it just needed the scale flushed out.
yes, did you WASH the baking soda out thoroughly? must wash it out good...
Most of your standard cheap car batteries arent worth reconditioning, the positive plates tend to fall apart, the grids are solid but the iron dioxide lead paste on the positive plates is just a paste, and after a couple of years they become brittle. Your more expensive automotive batteries you can get away with reconditioning only if the positive plates are tight and thick, otherwise not worth messing with. The same with the golf cart batteries are the same, the cheaper ones have thin plates and fall apart, but the more expensive ones are worth trying. Now forklift ilfa batteries you can recondition, because the plates are made thick with tubular design and are 5 times as thick as standard car battery.
The way you can tell most times if the battery is able to be reconditioned, is dump some of the acid out, if you get really dark almost black, or redish color acid coming out then probably not going to work, this is because the batteries positive plates have fallen apart and become so soft that when you empty and flush, the rest of the plate will just fall apart, the positive plates almost always fall apart, but the negative plates usually stay good, and if rebuild battery you can reuse the negative plates. I have recondition batteries for years, i have reconditioned a wide variety of batteries, i have even taken batteries apart and repasted positive plates with iron dioxide and put batteries back together. I have casted new plates and completely rebuilt batteries for projects. I have reconditioned forklift ifla batteries and even cased new plates and completely rebuilt forklift batteries, i am offgrid and run on 4 forklift batteries, and cost of forklift batteries, i decided ill just take apart, pulled all plates out, completely clean plate grids and repasted and put back together. All 4 of my forklift batteries have been complete rebuilt, and going on 13 years and show no signs of wear. For those that asking, you can buy battery acid at most autoparts store, it comes premixed 35% acid and 65% water. The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries. This range indicates that the battery is fully charged and in good condition. If the specific gravity is below 1.225, the battery is discharged and needs to be charged. If the specific gravity is above 1.299, the battery is overcharged and may be damaged.
This is one of only a couple videos online that actually show that once a battery fails due to age, there is simply no magic potion in existence to magically restore a worn out battery to new condition. The only somewhat exception to this is if a battery fails strictly due to sulfation and not from internal shorts between the plates that buckle and pierce the separators or if the plates simply fall apart. There are some industrial methods and equipment out there that can restore a sulfated battery to a useable condition but I am not sure of the procedure involved so I wont comment on it, I only know there is a way and apparently it does work at least to some extent.
I did four out of five so far but different way put dumb charger on 100 amp boost for 15 minutes let sit for half hour repeat five times worked well..
did you use new acid or the old acid?
Where did you get your electrolyte that cheap? Battery acid is just so expensive... Cheapest I can find is $20 for 64oz. How much does your battery hold? 64oz? How much do you think a 6v flooded golf cart battery holds? I'd like to change mine out also. I was going to do the old welder trick and dump/replace... or dump and put in new... thoughts?
Amazon. I was extremely successful with my attempt. I also used EDTA with the baking soda.
Battery specific gravity is an important metric in determining the state of charge and health of a battery. It is defined as the ratio of the density of the battery electrolyte, relative to water with which it would combine if mixed evenly.
The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries, which indicates that the battery is fully charged and in good condition.
Understanding battery specific gravity is crucial for maintaining the longevity and performance of your batteries. Factors such as temperature, battery age, and battery type can all impact specific gravity readings.
Additionally, testing battery specific gravity and interpreting test results can help you troubleshoot issues and take appropriate safety measures. An interpretative chart can be a useful tool in understanding specific gravity readings and determining the state of your battery.
I am wondering on a new quad when it sits for an extended time theyalways need a charge any toughs?
A few things wrong here.
1. baking soda/sodium bicarbonate will kill the battery, yes it will neutralise the acid, but it will remain soaked in the separator, which is typically natural fibre or porous plastic, so when you add fresh acid or you add water and charge (which produces acid), the acid will continue to neutralise
2. you will never see anything "collapsed". What happens is you get plates crack and/or the separators disintegrate. Visually you will not be able to make any determination on the condition of the battery just peering down a 3/4" filler hole.
3. a clean battery with fresh acid (35% acid to 65% water) should show you 12.6+ volts / 100% charge. Either the acid is not right concentration OR point 1 above, the residual sodium bicarbonate has just neutralised your new acid (hence the 9-10v)
Regardless of the above, you cannot just pour fresh acid mix into a battery and expect it to come alive. You need to have the lead plates (lead and lead oxide) in the right state so that the redox reaction (the one which lets the acid in the lead create current) can do its thing. If the battery was dead flat before you started, your electrolyte mix was close to being water (well a very weak sulfuric acid), your +ve plate which started out as lead oxide will have swapped the Oxygen ions for the SO4 (sulfate ions) and be coated in lead sulfate. Adding more sulfate ions (via fresh sulfuric acid mix) will only make the problem worse. You need to reverse the sulfation and the only way to do this is to charge the battery with fresh water.
Bicarbonate serves as a buffer solution neutralizing acids and bases, so I would recomend to flush the battery with filtered water, I would say distilled but it is hard to get distilled water so just filtered water or even bottled water would do, and then use the acid.
:-)
thanks so much.
Distilled water is not hard to find. Every pharmacy carries it.
Boiling water or filtering it doesn’t remove the impurities... distilled water isn’t hard to find either, it’s in every grocery store in the US.
If you aren’t sure of something, don’t go around making suggestions.
Distilled water is 88 cents a gallon at Wal-Mart...
Hang a lid half off of a pot or pan of water, the hanging half end will drip water outside the pan.. Collect this water. Whala distilled water
Okay. Got you. Two small questions. Where do I buy the battery acid? Is it diluted or full strength? I'm kind of new to this type of DIY project. I did enjoy your video! Have you found that a lot of these DIY projects go a lot better with a helper? That excludes my Wife. If she helps, I have to take her out for dinner!
O'Reilly's or Autozone
I have tried some of these "methods" and the Epsom Salts were an abject failure. Cleaning out the cells and replacing the electrolyte failed as well.
Dumping old electrolyte and then using baking soda and water to clean I have mixed feelings about. Putting a base in a old battery cell in reality should be a no no on first thought. However it may have some helpful and desired effects. Assuming we are using 100% sodium bicarbonate and distilled water. The bubbling from the c02 productions may help scrub sulfated lead off the cells. If we are Assuming the battery plates are 100% sulfated not allowing any current to pass through them. you may have to do something like this to even have a chance to properly charge. Don’t know if these two things are the best to use even. But I could see how it could be. If we did wash with distilled water and bicarbonate solution it will have to be cleaned very well after the process with warm distilled water 6 or more times removing all of the sodium sulfate, hopefully lead sulfate, and H2O2 “peroxide”. You will be leaving some water behind diluting your electrolyte some keep that in mind. A hydrometer is your friend. In keeping and maintaining a lead acid battery. Meet to be checking them after something like this. Because you have diluted electrolyte when charging you should charge slow to evaporate some of the water out with a high frequency charger/desulfurization device. Reason being if the problem with the battery in the first place was from being sulfated you will need to deSulfate it in some capacity. Let me tell you something you do not want to hear it will take many use and charge cycles to start getting results from the battery if No other problems existed and you removed the Byproducts left from the co2 generator you made earlier. Not sure how they would effect the process of the lead acid battery producing power. But that brings me to the point I wanted to start with about another problem you could be having with your lead acid battery. Sometimes good batteries die unjustly. Here is how. The electrolyte get low no one thought to check the water in it over the last 2 to 5 years. Then the battery was needed and was used hard causing some of the over sulfating to accuse. Pretty sure. But the biggest of a battery problems could happen. And does often. That is the lead connecting back bone can get hot enough to drop plates off a cell randomly or the actually just open the cell from the battery totally. If you are trying to recondition a battery you have seen a open cell. Nothing you do will ever bring it back. Unless you open it and repair the circuit. You tube how check cells. After you let it sits off charger what does voltage fall to? 14.4 volts is a heathy fully charged battery with no load. 13.7ish is typically what you will see on most new batteries fully charged no load however. So a good cell should read somewhere around 4.5 max. 3.0 volts good cell but needs charged. No voltage a bad cell. So if you see 9 volts across the post you after it sits and it settles to 9 ish volts you probably got a dead cell. Or one that will not go above 4 v probably got 2 bad cells. Hell keep it on the charger little longer you might even see 3 bad cells shortly after that. So keep that in mind when doing this. Make sure your cells are intact before you go through this. If your battery has around 6 to 6.5 volts before the reconditioning you may have a battery good enough one to try reconditioning. Check electrolyte solution with a hydrometer and but one or 2 of the 15 dollar desulfating device off Amazon and run it through some cycles on that and the chargers. If you are not rebuilding the battery from ground up it will have to get some cycles done on it the bring it back to good health. Reconditioning them will not bring back to 100%. 85 to 95% sure. If you don’t think your battery is fixable go to your local scrap yard with a volt meter. Get rid of our old one and probe a few of the ones they have bought. Most scrap yards will sell you anything they have for little more them they paid or it. 5 to 6.8 is the range I would hunt for. 2ish volts on the 3 cells kinda tells you all cells are connected. 8 to 9 is only 2 cells , 4.8 or less only one cell is in tact. Not 100% of the time this is true but for the most part you will find it falls inside of this. And but 2 or 3 of them. What 30$ if you get one to come back you are still ahead. Hopefully this helps you with misdiagnosed battery failures. Before you start trying to reconditioned one. Ps cheap, badly charged for whatever ever reason and dropped batteries can contribute to damaged cells. Keep that in mind when you rack your brain on what was done wrong in the first place.
I used EDTA with the baking soda and mine was fully charged before the charger
Also, have you ever tried the welder trick to break up the sulfate?
We take 4 to 5 old batteries and boil off they water to just have h2so4 then put it in one or 2 barriers and bang new batteries
just rinse with distilled water. If rinsing would work, and that is hit or miss, then that would do it, then put the right mix of acid and distilled water back into it. It's hit & miss since you can't see between the anodes and cathodes to see just how bad it is.
The lead plates within each cell should look like they're not touching, which is usually the main cause of a lead acid battery failure during the charging and discharging fees of electrons, leaving the lead and sulphate plates causes corrosion or buildup of sulphates which intern cause an unintentional short within anyone battery cell. If anyone battery cell reads below 2.1 V the battery state of health will be compromised even if the SOC state of charge reads optimal within the 12.4 to 12.8 V range with ideal voltage always being 12.6 V after a quantified load test is performed with the gold standard being a carbon pile resistance type manual battery load tester. While electronic devices can be a good and fast test to indicate a batteries condition. we must first fully charged that battery with a known working charging source a.k.a. 10 amp battery charger while also taking note of the batteries, internal temperature and electrolyte levels. It's electrolyte level is low always add purely distilled water or reverse osmosis water to a level approximately half an inch above the top of each of the plates in each cell. Keep in mind that these cells are in fact, individual cells meaning each cell contains its own to similar metals within an electrolyte solution.

If you use that lincoln behind you an hook up to the battery it'll hold charge.
Pouring baking soda into the battery cells will neutralize the sulfuric acid in the electrolyte to sodium sulfate that cannot discharge to lead sulfate in the normal discharge reaction. This will also permanently reduce the capacity of the battery, which was most likely already low.
The best recommendation for potentially recovering a sulfated battery is to save your money and try using a long, slow charge. If you have a battery charger that has a reconditioning or equalizing charge mode on it, that may be your best bet. “Use the equalization charge mode regularly, about once a month, on deep-cycle lead-acid batteries to extend the life of the battery. Regular equalization charges prevent sulfation and stratification by balancing the individual cells and properly mixing the electrolyte.
Why not take the lead out of several dead batteries, take it to the scrap dealers, get money and buy a new battery, its prob easier.
Where to buy battery acid
You have to cycle it a few times, ive done it few years ago just adding distiled water n ep salt on garbage batterys and it helped alot but they was shot shot b4 i did it got me a few weeks more out of them/ i trickeled them then slowly drain hook up a bulb or just put it in a vehicle leave lights on n repeat/ also i might of missed it but want charge them with caps loose as it should slowly leak some acid out as she charges.. im about to try it today again myself on a battery thats not as old as the others i tried before was 7 or 8 years old this junk autocraft silver is 4 years old n garbage.... IMO FOR new "NAPA Legend's" 100% the way to go for long lasting and keeping cca my last one was the 8 year old battery lol they are pricey! Royal king is a good budget battery and i beleave there made by excel just my 2 cents
You be lucky if you can obtain any battery acid for sale nowadays. Its only for commercial companies, no sale to general public. Some can get through 'cooking it off ' drain cleaner solutions? But easiest is just recovery from 'old batteries', filter out gunk and reuse these.😮
Thx for the heads up

I have thought about trying to rejuvenate a 12v battery by replacing the electrolyte. This is my thoughts on how you did the test.
1 - Baking soda will neutralize the acid in the battery; you ran the cleaning twice. Did you flush the baking soda out with clean distilled water before adding the electrolyte?
2 - Is it possibly that there could still be some of the baking soda mix in the battery that might have deluded the electrolyte?
Did you try "cycling"? Bringing down the voltage with a load and, then, recharging. Do that a few times. I saw it on RUclips.
will do, thanks
Top off with battery acid. Run 200 amps for 15min till boiling, rest for 1 hour and repeat 5x. This will just start the battery.
I have had very good results by adding the baking soda water a few times... then washing out the battery many times with water... get all the baking soda out... let the battery dry upside down... then filling with 35% Acid 65% water (or ready to use acid) then trickle charging it for a few days (low amp charger). Trickle charging is the best. If you have no charger find a AC/DC wall wort converter that has 'OUTPUT 12 V DC'. Strip the ends. - you can find these at a thrift store or around your house... And if you want to really hill billy it... use orange soda instead of baking soda water... but FLUSH it out many times ~ if this doesn't work - nothing will IMO. tc
So you use new acid? not the old acid?

Once you've determined that the battery is clean and the electrolyte battery acid level is that the correct specific gravity of 1.35 using a battery spectrometer or electrolyte testing device such as a rubber bulb dial indicator similar to Coolant antifreeze tester. Then place the battery on the lowest amperage setting ideally 1-2 amp trickle charge setting and leave charging for three days straight periodically checking the electrolyte level. Generally speaking, even though you will see bubbles with this low amperage setting, they will not cause significant electrolyte level loss but rather wants the 72 hours is up. You will notice the levels have decreased and need to be filled accordingly. I have performed above procedure with great success when reconditioning batteries.. unfortunately what I find with RUclips is often times RUclipsr get either lucky or there was nothing wrong with the battery to begin with? it makes for a great entertaining show but if it were that easy, none of us would have to buy car batteries again it's plain and simple. Clean the battery properly as many as a dozen times with a garden hose or pressure from a pressure. Washer is the best way I found to clean the plates. It's not until the water in which you dump out is as clear as the water in which you dumped in when the battery has been properly cleaned. I've found agitating shaking and turning the battery upside down to greatly increase the odds of a battery being restored. Remember these lead and lead sulphate plates are two dissimilar metals in an electrolyte solution, which is by definition a true battery if any of the eights within any given cell are touching one another this creates an unintentional ground or a one metal electrolyte solution, which will not create ample amounts of electrical current needed to start a car. The more surface area that is cleaned and able to allow the movement of the electrolyte solution, causing the electrons to go back-and-forth from the anode to the cathode will greatly increase the odds of success. It's OK to use regular top WATER during the cleaning process once the battery is completely cleaned simply rinse one more time with purely distilled water and then your battery acid electrolyte solution. Be sure to test the electrolyte solution in which you're using with a proper tooling as the range of specific gravity must be achieved in order for the battery to operate properly.
Epsom salts do not work, neither do ANY of the other "remedies". When a battery cannot be charged to 600 cold cranking amps, or it won't start your car or truck, that sucker is dead, dead, dead. Stick a pry bar into your wallet, and go buy a new one with a warranty. If you have a battery with caps on it and want to make it last, use distilled water only. Wash your battery with distilled water everytime you check fliuds in the engine compartment. That dust you see on the road is actually RUST from other cars. The dust rust you see on your battery causes a high resistent short that slowly kills your battery and maybe even your alternator. Protect against battery corrosion by using the green/red felt pads or the old way with petroleum jelly brushed liberally on battery posts and cable connections. Blow the alternator with high pressure air not directly pointed into the vents to keep it cleaned out. Adjust the belt tensioner periodically on your serpentine belt and check for cracks or splits in the belt itself. Do not use belt conditioner on your car/truck, use it on your lawn mower ONLY. Use a rubber protectant recommended at the car parts place of your choice ( good for tire sidewalls to keep from cracking). Got questions? Go to Scotty Kilmer's channel here on YTube, he has LOTS of answers, good ones, too. I've gotten lots of good advice from Scotty, fixed a lot of cars and trucks with his online help. Good Luck!
longshorts3 thank you for your advice, i usually post comments like this to help others. do you have any other maintenance advice? i don't watch Scotty Kilmer anymore, i got fed up with him after he started posting fake video titles like "This Scan Tool Destroyed My Car and I'm Mad as Hell" to trick you into watching his videos.
Great video
I feel your flashlight 🔦 pain
What ratio water/acid? Maybe that's your problem!
You didn't DESULFATE, so your lead was all full of gunk and couldn't produce the proper charge. Your "cleaning" was no more than a chemical reaction between the sulfuric acid in the battery and the added baking soda. It did not "clean" anything, as you need to desulfate the corroded lead.
Only battery solution, great😀
He said it didn't work
The battery acid in my battery is brown so I think I am going to try this .
Wear polyester it wom't burn from the acid
One problem is you cannot put pure acid in a discharged battery.
When the battery is dead the electrolyte is weakened and has more water content.
Hydrochloric Acid, 50% (v/v), 4 L, 3580-1 higher ratio
When prepping for battery acid replacement gloves glasses long pants are great but dont forget a condom. It could splash. Noone wants to look like a Ken doll.
And a ballbag
@@scottcrowley2061 that goes without saying everyone knows to wear a safety banana hammock when handling corrosive acids
Put them on a 200 amp charger and roast them plates clean
Hit that thing with a few hundred amps right off the bat
EDTA not baking soda or epson salt. If you are going to replace the electrolyte anyways just add the EDTA to the existing battery and flip on the head lights and let it discharge. Recharge then drain. Rinse with distilled water and refill with new electrolyte. I can add backing soda to vinegar and get foaming but that does not mean it is cleaning anything. I would say that the bubbling is a fools folly you are getting a reaction but you have no way of knowing if it is doing anything use full. You can get a 4oz bag of EDTA for $8 off Amazon.
wow, thank you. have you done this and it works.
What is EDTA?
@@heinrichwaldeck2220 C10 H16 N2 08 Ethylenediaminetetraacetic Acid
Agree completely. Used EDTA and refilled with electrolyte and they were gulley charged before the trickle charge
Made me laugh 🤣🤣🤣🤣🤣
HF flashlight.
Buy a new battery - its not going to let you down
This is just superb, I have been researching "reconditioning a car battery" for a while now, and I think this has helped. Have you heard people talk about - Ammaceen Reconditioning Rabblement - (do a search on google ) ? Ive heard some incredible things about it and my brother in law got cool results with it.
Lol
Nogood
Too much blah blah!!!!
He must vote democrat. Seems to seek disappointment ...
Lol no doubt
best multimeter you can get from harbor freight :)
The lead plates within each cell should look like they're not touching, which is usually the main cause of a lead acid battery failure during the charging and discharging fees of electrons, leaving the lead and sulphate plates causes corrosion or buildup of sulphates which intern cause an unintentional short within anyone battery cell. If anyone battery cell reads below 2.1 V the battery state of health will be compromised even if the SOC state of charge reads optimal within the 12.4 to 12.8 V range with ideal voltage always being 12.6 V after a quantified load test is performed with the gold standard being a carbon pile resistance type manual battery load tester. While electronic devices can be a good and fast test to indicate a batteries condition. we must first fully charged that battery with a known working charging source a.k.a. 10 amp battery charger while also taking note of the batteries, internal temperature and electrolyte levels. It's electrolyte level is low always add purely distilled water or reverse osmosis water to a level approximately half an inch above the top of each of the plates in each cell. Keep in mind that these cells are in fact, individual cells meaning each cell contains its own to similar metals within an electrolyte solution. So when filling one of the cells the other remaining cells will typically remain at the same level. Each of the 6 battery cells are connected in series I in order to create at 12.6 perfectly charged and perfectly working healthy battery once a load test has been performed. 6 x 2.1V in series equals 12.6v OPTIMAL BATTERY VOLTAGE. We must realize there is no such battery that consists of maintenance free as this is just an advertising gimmick in order to entice consumer interest to best sell their products. even when it batteries says maintenance free, the battery can be disassembled with the use of a utility knife and a hot air gun or hairdryer to soften up the rather rigid plastic materials in which the battery is encased in. Always perform this task wearing the proper PPE in an outdoor or well ventilated environment in order to inspect and properly clean a standard lead acid battery. The fill holes are simply just that electrolyte fill holes and is generally not considered a best practice when inspecting the internal battery structure. This can better be achieved with the use of a endoscope type camera of any quality that could attach to your cell phone or have a dedicated high definition screen with a LED light at the end of the scope to better diagnose a battery condition. if a battery is not completely or sufficiently cleaned of its shedding materials all of the work being performed will be rendered useless as a starting battery for an automotive setting.
