CAN YOU FIX A DEAD CAR BATTERY? - How to rebuild a car battery DIY Fix a Dead Battery
Can you fix a dead car battery? Yes, you can, well sorta! In this video HOW TO REBUILD A CAR BATTERY for UNDER $5 BUCKS we see how some baking soda and Epson salts can fix a Dead Car Battery Fix and Revival of a Dead Battery.
This didn't work the first time for me when I tried to rebuild a car battery in my 1967 Porsche 912/911, it took a few tries before I found that it takes about 8 to 10 ounces of epson salts per liter of distilled water to get the right mix.
But fixing a dead car battery isn't hard to do, but the time it takes to recharge or rebuild a car battery it might be better just to buy a new battery. This process takes several days, and if you need your car sooner, then by all means just buy a new battery and maybe keep your core (old) battery as a back up and follow these steps to rebuild a car battery.

Don't drop or rattle your battery too hard or the lead plates will dislodge and your fucked. You do want to slosh the baking soda/distilled water solution in the battery though, just not crazy hard. You know what I mean? Anyway this method worked fantastic with my battery. It's only 2 years old, but I don't use the vehicle very much. I did go to Harbor freight and buy a cheapo $10 trickle charger with the solar panel. I've heard good reviews on it, so I'll have to see. I payed $150+ for the stupid battery a couple years ago and it's already gone up to almost $200. This is January of 2024.
Yes baking soda works. Just did it. My battery died but brought back to life.
Hello it's nice connecting with you, how's it going with you over there?
Batteries die because the lead plates create a sulfate on the plates. Eventually the sulfates build up to the point that they no longer flow electrons . Cleaning may expose more of the lead and get the flow going again, but usually by this time the lead plates are pretty much used up, so even cleaning the sulfates and putting in new acid will not save it, it may have voltage but very low cranking amps. Another old trick was to overcharge the battery with a high amp charger which would cause the sulfates to flake off the plates, but this was only a temporary solution as well. When you've got no lead, your battery is dead.
OLD SCHOOL You are correct , sir.

Batteries are made with two types of oxides. This ia paiste made of sulfuric acud and lead. This paiste is called posive msterial which is then applied to the positive grid after drying to cure it then becomes a positive plate. This is where the battery gets its voktage .the negative plates are formed in much the same way .but chemicaly work differently.the positvive provide the voltage and the negative plates are there to carry the amperage from one plate to the next..
everything has a life and nothing beats new,esp batteries,i dont' know about most people but to me a car truck that won't go state to state, its not worth much,new batteries,new belts,new hoses,every 4 years,no matter what,oil changes every 3500x3 then go to 5000 x3 then back to 3500,keeping the pan clean is all of it,OLD SCHOOL you know nothing beats new or first design,the first anything was designed because the guy needed it,hang in there

You understand my pain lol thanks for watching!
Go with spending the money on an Optima battery. I had one in my 2000 Montero for 11 years plus. When I had to scrap the car after my daughter let the coolant go way low and blew out one head gasket. I took the battery out and it is still working perfectly 5 years later! $325.00 Well spent as I probably would have had to change batteries 4 or 5 times during that 16 year period. ONE MAJOR BENEFIT ...gell pack batteries will not outgas or leak and cause rust in your classic Porsche 👌👍
I’ve got a yellow top optima gel battery and it’s still good and strong after 6-7 years now of being used and ran dead on several occasions as well as drained on several Saturday nights over them years in my dirt track car.
Don't forget to turn then upside down for two weeks a year.
There are way better batteries than optima
Back in the early 80's I worked for a used battery service' the owner had a contract with JCPenney's/Sears Kmart to buy all their old batteries' we'd pour all the old acid water out and use a 50/50 mixture of white distilled cleaning vinegar to wash them out then rinse out and repeat' fill with new acid' place them on the charging tables' up to 200/250 batteries at a time' hook them up all together in parallel and charge them on 2 amps for 3 days' then let them sit for a week off charge' about 25% of them would not hold charge' the ones that did' we were selling them for $15.00/$20.00/$25.00 depending on appearance' some would last a couple of months some would last for years. Slow charge is the key after cleaning and new acid.
What do you do if you don't have the caps on the battery
@@pawtaylor Back then the majority had caps' there were a few that were sealed' on those we had to peel the manufacturer label off the top of the battery and under the label there were caps' they were recessed and sat flush with the top of the battery' on some you could see a small hairline crack between the cap and top of the battery' a small flathead screwdriver or pocket knife and pry them out. On others you could see the outline of the seal' on those we had to take a utility knife and cut into the outline of the seal to separate the cap from the battery and then pry it out. I remember being in the lower shop and all the sudden BAMM!!! Sound like a cannon had went off from the charging process' I could feel the battery acid on my face and arms from being in the air' there was a couple of times they blew a hole clean through the tin roof of the charging area.
This works, I had a car quest gold last 12 years doing this. In brutal cold to insane hot.
Good to hear! Thanks for watching
without load testing, the battery after doing the recondition 12 v means nothing.
That’s what i was thinking, where was the load test, you can surface charge just about any lead acid battery.. load test the fooker to it full CCAs and then show us..
You are correct
@@formosabrowning3539 at my workshop, we managed to charge a four lemons to show 12volts, We were Successful in lighting a tiny LED bulb on a test light for about 40 seconds.. (did I technically recondition the lemon). 😂
You are so correct A+for you !!
Yep. Volts ain't amps. 😂
Sounds really good thank you for the good advice
No problem 👍
I've got 50 12 volt battery's that I'm now rebuilding thank, you
thank, you. it works now I've got 50 new rebuilt 12 volt battery's
I keep a battery tender on my old truck battery and lawn tractor when sitting for extended periods of time. Works great.
That's a good idea!
Battery tender will constantly charge it, which means that the internals of the battery get warm, distilled water will evaporate, overall liquid levels will drop, acid concentration will be too high and cause corrosion on lead plates inside the battery - this results in a residue that will short circuit one or several of the canisters. Battery tender wont know that there is one faulty canister and will overcharge the other ones to reach the 12 volts. While doing that, it will further overheat the other canisters. The battery will start a car for one time or two and then it has lost its charge to 9v or lower. Also when one of the canister is shorted out or low on liquid, the battery will start boiling when alternator charges it. What the process in this video does is remove mentioned corrosion residue and clean the plates. Then refill with clean acid or salt water. It helps but some of the plate material is still gone and its not comparable to a new battery. Its OK for warm climate areas and petrol cars but not high cranking current demanding diesel cars. Battery tender will work too without any issues but only if you check the liquid levels and top up with distilled water - of course if the caps on the canisters can be removed - on most newer batteries they cant because battery manufacturers use ultrasonic welding to make the covers not removable so that you would have to buy a new battery instead 🤓
Love your videos. Arizona ROCKS !
Thank you Johnny, appreciate you watching and leaving a comment.
Sure are a lot of experts in the comments section
Use sodium sulfate instead of epsom salt (Much gentler on the electrodes and does not heavily oxidize the positive plates when charging And it's even more conductive too) And it also has much higher output current than magnesium sulfate. Alum sulfate will also work as well. but its not the best choice. Just add about a tablespoon worth into each cell (Not too much!) This will raise the conductivity of the electrolyte if its weak. and also aid in forming the electrodes gently. re-forming the lead sulfates into lead and lead oxides. without over-oxidizing the positive plate like the magnesium sulfate/espom salt would I have had nothing but bad experience with magnesium sulfate and several tests ive done. it is simply too aggressive and attacks the positive electrode quite strongly. (it is fast at forming the lead oxides. but it will increase corrosion) No need to use any baking soda either or removing or replacing the electrolyte.. Just charge the battery with the sodium sulfate added to it for a long time at a low current and allow the voltage to rise to whatever it takes to accept that low current (Charge at about C1/100) Until the voltage is about 14-16v. Then the battery can be put on a normal charger and held in absorption (14.4-14.8v) for several additional hours. until the current has stabilized at a low value. Watch for heating of the battery. Take a measurement regularly if it starts warming up at any point. let it sit for several hours to cool completely. Regularly check the voltage and current as well. just to be sure theres no shorted cells or anything unusual happening You can also add about 1/8 teaspoon of boric acid or borax to each cell. as an additional additive. it creates a protective boron layer on the electrodes. specifically the negative. resistant to sulfation. if all else fails and you cannot revive the original sulfuric acid out of the lead sulfate stored in the plates. (Cannot raise the specific gravity) Only then may it be time to try replacing the electrolyte with an alternative such as alum. sodium sulfate. mixture. or baking soda (Possible electrolyte alternative could be washing soda or sodium carbonate. as it is the strongest alkaline electrolyte ive found that can still form the lead oxide in the plates. creating an almost super-capacitor like battery performance. Very tough and hard to kill. can be charged and discharged thousands of times with no damage. Deep discharge is completely harmless) You will get a significantly lower voltage though. between 8-11v so there is a drawback for going completely alkaline-for the electrolyte. PH will be roughly 10-11 if fully converted to alkaline.
What type of sodium sulfate and where to get it.
@dallaslouie Thats my question. Where you buy the stuff?
For some of the comments who are quick to go to the shop and replace or repair , Please such DIY are for people who find themselves off grid , imagine you are in Alaska or some very rural African place , this can really help. And again some people even if they may be located in big cities they still don’t have money to replace a battery .
Well said.
Awsome dude, thanks it really works. Try the ark weld method first. Then the cleaning process. Add new Epsom solution afterwards.
rubber gloves, safety glasses and a good mask thank, you.
Thanks for trying this out .Other attempts suggest that Epsom salts will result in a battery that will only give 9 volt but last for over five teen years .That is interesting for making large static battery banks for off grid use where 48 volts is wanted do 5 of these 9 volt batteries will give the 45 volts which works for them .The upside with salt battery it seems they don't get damaged from total discharge but they don't preform well under large loads . Many You tubes on Epsom salt replacements .Also in third world many KZhead's on how to melt the lead plates and remake new battery using acid systems . LSO many you tubes an using welder equipment with 200 amps to boil battery in five minute bursts until battery works again . I have yet to see a 12 volt Epsom salt battery return 12 volt solutions for any interesting time periods so very interested for your results now 11 months on .Can it supply cranking power to start gasoline engine .I don't mind to gang together several to get cranking power for my 13 HP marine engine on my boat and for domestic us . Li thuim ion ferros oxide phosporn type Li Fe PO4 has problems with cost and expensive chargers and cold temperature charging and high temperature s and Alternator charging in marine use . Lead crystal battery costs per cycle is also a problem . We need more people to do these experiments to see if we can rescue lead acid batteries to keep from forkingbout big bucks every few years especially in warm countries where lead acid batteries have much shorter lives than temoerate regions
It's a 12 volt battery not 48 volts
You wire the batteries in series to make 48 volts. That is exactly what the OP is writing about. Please read his post.

After dumping out the baking soda water you should have rinsed the battery a couple times with water to get all that out of battery, then before adding any of your Epson salt concoction used a specific gravity tester to test the strength of your concoction to ensure proper strength 1st before adding any of it to your battery. Filter your used electrolyte and pour equal amounts into each cell and top up with your concoction. After adding the proper strength solution to battery, then put charger on deep cycle battery setting if you have that setting. A smart charger may do the same thing by charging at different rates until fully charged over a 24 hour period or longer. I have seen batteries after trying to fix them that showed 12.8 volts but as soon as I went to turn the engine over the battery went to 7 volts and would not turn the engine over. This indicates that simply charging to 12.3 or above doesn't always translate to the battery being fixed, especially if the battery originally went dead while below freezing and as such froze up and broke some plates inside the battery. I usually use the specific gravity tester in each cell to see which cell is showing weak solution and which are showing normal, I will remove with a suction device like a fluid transfer pump or just the bubble device I am using which is the specific gravity tester, until the fluid is below the plates in that cell. At this point the strong concoction of Epson salts and water can be added just to the specific cells that are showing they are below normal on the tester. This saves a lot of time and most of the original electrolyte gets to stay in the battery. After this I put the covers on the cells and charge for minimum of 24 hours and with all of this there is no guarantees the battery will ever function like a new battery. Prevention is still the best way to look after a battery, remove either it or 1 terminal when not in use for extended periods of time, recharge every 3 months, do not store on a concrete floor but rather on a bench or wood of some kind.
I have to agree with everything you said here with the exception of the concrete floor. This is a myth and a hold over fallacy from the days when car batteries had metal in their cases. New batteries up today have cases made entirely of plastic. You can put a brand new battery on the concrete floor in your shop and put another one on the wood counter and check them a month later there should be no difference whatsoever.
all your blabbing but its redundant. the PH of the acid will literally self balance with a charge. He could do all that but it bbn isnt neccessary on an old junky battery.
@@SEPHICHI420p
Volts is not what you need it is also amps that the battery holds that is important.
You got bigger problems than a battery, someone took your engine and replaced it with a spare tire.
Finally someone noticed lol for watching Tom
@@ArrowheadGarage I have heard of white vinegar on top of 1/4th.cup of baking soda per cell . Then add your mix of epsom salt, wash it out extensively with several fillings with water, drain completely, then add back the settled acid, Why did you not add back the acid, only a charged battery holds the electrolytes in the plates, a discharged one has 80% of the acid in the liquid. Can you say why u did not add acid
Don't make me laugh! 😂🤣
He tried, but is healing up from that .45 cal. Slug through his leg!
@tom mak, good joke, made me laugh but i'm sure you know porsche engines are in the back
I believe the salt water was supposed to be poured out and rinse the battery out once again with clean distilled water. Then refill the battery with sulfuric acid from one of your local parts store. Then it would have worked.
No, the Epsom salt works as the electrolytes instead of the sulfuric acid. Although he could have filtered the old acid and just topped off the fluid with salt mixture additive after cleaning
@@vexxcloud5543 It seems like a lot of salt.
Too much Salt is bad for you.
@@dalehood1846 lol. Too much battery acid is bad for you too. To much anything is bad.
I just saw a clip with a doctor recommending drinking the same to purify your stomach.... 1 Litre distilled water, 1 tsp baking soda, 1 tsp sea salt. Divide in 4 and drink every 2'nd hour... Makes sense 😂 Tip: The distilled water is polluted when poring it in a "bucket" like that...
Thank you 🙏 it is great 👍 to know for less money 💵 💡⏰🎥👍👋
Thank you wonderful knowledgeable information about cheap battery second life.
Glad it was helpful Paul!
Yes a load test will check to see if you can pull a load. Easier yet. Let battery sit overnight and recheck voltage. If voltage drops it’s not going to work. But a load test is better. But if you don’t have a tester check voltage and recheck 24-30 hrs later. If it drops from 12.6- 12.0 it’s not going to work . Nice video . But remember to load test it as well or sit and watch for voltage drop.
hello ......how are you doing??
is it ok to use sulfuric acid to recharge after washing battery with baking soda?
after Getting the battery to take a charge but what is the cold cranking amps. I didn't see a load test. it can show volts but can it hold up while in use.
about six months in and battery is still doing well
@@ArrowheadGarage ❤❤
👏very well done, kinda, yes the plates will create a build up, and this build up flakes off over time and settle in between these plates creating a short circuit. Getting this gunk off and out between these plate is a must along with putting new acid in but if you first filtered the old acid and poured back in and connected a old none smart charger and forced charged that battery on high ,,not the start setting,, and let it set a few days. Battery would have become warm, bubbles would have appeared and alot more flakes would have come off. Then shake and pour out. Put in new acid and charge. !!BUT!! a smart charger, A charger with a chip, will not force charge any battery. A old transformer type charger can bring back a completely dead battery, a smart charger would see it as a short circuit a (bad battery)and kick off. They do this even on a week battery that won't take a certain amount of charge over a certain amount of time, they just kick off.. old chargers, they charge using a transformer, not through a programed chip that's also design to test the condition of a battery and that's what they all do, and if a battery isn't in near perfect condition these charger just keep kicking off. Look for at Flee markets. Garage sales, maybe ebay? . I just found another one for 10 bucks at a flee market in great condition and if you had it on that battery you would have seen over 14 volts on your volt meter forcing a charge on that battery. You read 12 volts with charger connected to it, your charger kicked off...a bad battery can show 12 volts, but it's about available current (amps) that does the work,, you can sometimes get a little more life out of a old worn battery, but not with a digital computer chip charger. These Chargers are much cheaper to make and sale. Get an old one to have around and you won't be replacing your riding mowers, ect, batteries as often either.
i can vouch for this. i used an old laptop power supply and soldered in some battery clamps on the output and it'll easily charge to as high as 15 to 16 volts if u let it sit. im not sure how good that would be for a battery under normal circumstances to be charged that much more than its intended output, but for this use, i think it will be ideal. i guess i'm gonna find out as im about to attempt to refurbish my battery in the next day or so.
I have an old transformer type charger but it doesn't work anymore. Do you know anyone that fixes them . I'm not sure what the problem is or if it's worth fixing
Dunno if u have a tractor supply where u live but they still sell the old type chargers for like 60 bucks I have 1 of them and also an old charger that's about 30 yrs old just because I hate the smart chargers for the facts u stated we had a battery totally dead and all we had was a smart charger kept kicking off so we didn't have jumper cables at the moment do now anyway we took 2 pieces of coated wire and hooked the dead battery to a fully charged battery for about 30 minutes enough that it would spark and the smart charger finally recognized it didn't have a short in it and finally charged it
"The wife gets a little concerned" LOL
She have too " LOL😊
now, I see what makes a battery cell goes dead is that the lead plates inside the battery gets dirty. Again, thank you for you're video
thank, you for you're video
Why not take the old battery to a car shop to do the revival with fresh sulphuric acid? Epson salt is not the correct acid for battery.
Led acid batteries consist of 2 different kind of lead plates sitting in acid. This makes electric current. The plates wear out and become the same kind but a different lead together. So no current flow. Cleaning the sulfate off will help, but charging turn the places back to their original lead type. With sulfate removed there won't be as much lead, but there will be current flow, just not as much.
What do you have in the tote in the beginning of the video? It also has some liquid. Do you have a video of that too?
Question. How long does a battery last. I had mine since 2018. Do I need a new one. ?
Why not just removing the sulfuric acid and doing the clean out with the baking soda why not just put sulfuric or new sulfuric acid back in
Terry where do u get sulfuric acid
@@saltwell80 in USA it is available guessing you are from UK?

With this is a temporary fix, because if you mix those two things within that battery, it’s gonna eventually corrode the lead in it common sense. If you wanna fix a real better either go buy a brand-new one or pay the money for actual battery acid be smart.
From my experience it will worke for 2 days just enough to crank the car twice... But thank you for your efforts
Just watched from 2 years ago. Can't find the update you were mentioning. How did th we battery do over time?
THAT is a classic. I think that's the only 911 I'd want.
I just love the short wheel based long hoods!!! Thanks for watching and dropping a comment, I appreciate it!
I'm aircraft avionics tech. You makes me smile.
you need to remove your Epsom Salt water rinse it good, and filter your aced you drained out put it back with a little Epsom Salt in each cell then charge it heavy then see what you get, works better that way.
It's NOT EPSOM salt It's Baking soda!
What happened to the other half of the epsom salt solution after you mixed it? When you poured the finished solution from the pot and into the gallon jug, the jug was only filled half-way.
You can soak your tired feet in it!
Drain battery and flush it with a garden hose, then one rinse with distilled water. That dislodges any particles of plate material that build up on the bottom of the n battery and might be causing slight internal short circuits between the plates
Most important... Pour distilled water back in the battery for the final process..!
Well you know once you did the baking soda clean step step and then you Drain it You can go to most auto parts stores and buy battery acid I know at least Advanced auto parts has it But I would definitely check around
Cool thes will help me God Bless you are Angel I am Lady willing to learn how to do the proceso tank you.
Better yet, do the recommended maintenance, such as topping off with distilled water; make sure the alternator is in working order; belts tightened, etc.
Great videos as always sir❤❤❤ also can we put the indicators and scan charts for reference like the Keystocks software??
Yes, absolutely
@@ArrowheadGarage Would love a follow up with the capacity and lifetime added.
You need to rinse out batt after the initial 24 hours of the distilled water and epsome soak. Rince out batt several times with regular tap water. Then make some more epsome salt and distilled water mix and add to batt cells. Charge for 24 hours on slow charge. Now its a new battery.
You're pretty smart on this one lot of people don't know that
Wrong you need new electrolyte which is sulfuric acid after initial cleaning. You can buy it at some auto parts stores.
@@rickpaz9562 you do it your way I do it my way
Nice ride
I have used distilled water and it worked.
Before you start your procedure hold the battery upside down about 6-8" inches above the pavement and drop it a time or two...If the posts aren't recessed zip tie a piece of wood to it first... sounds crazy but trust me.
It sounds like youve been smokin some of the new stuff.or ya need to .
sounds good to me! Ha. You need to physically break the seals between the pieces of lead, so the liquid can reach all the lead. Am I right?
The plates in a battery have seperaters between each plate..without them the plates would simply short out .

You can neutralize sulfuric acid with baking soda and water then if ok to dispose anyhow you want
Makes good toilet cleaner
Pour it on a fire ant mound 😋
Get an alkaline substance to neutralize spilled acid. Ash from a wood stove may be used if nothing better is available.
That's what I want to know!!!!! also ...
How long does the battery last after that service
Ive seen 100% better batter rebuilds by guys sitting on dirt floors in India and 100% theirs actually worked.
Send us some links.
I buy those jogs of sulfuric acid from any auto parts store, and then drain and refill. Now this has worked for say, 6 out of 10 batteries I've tried, and my best guess for the bad ones, is damage to cells, or extreme contamination since I've never 'rinsed' or cleaned any of them. Using these ingredients is even cheaper.
How much does the sulfuric acid replacement at the auto parts store cost?
Doesn't the positive side of batteries actually deform? I heard that two used batteries will give you two almost pristine negative sides to combine to make an almost new battery with.
i was in the battery reconditioning bizz for 30 years. i'll give you a 2 out of 10. One free tip , dump the old acid in 5 gallon buckets , lock them up in an out building for a week, all the crap settles to the bottom. I never bought new battery acid. The next 1000 tips are not free. Think i'll write a book.
Put a load tester on it to check Cold Cranking Amps. Residual voltage isn’t telling you anything.
If there is no damage something you just need to charge it for 3 straight weeks to get it like new condition. In rare cases yes you have to buy parts for them
Quite an interesting video, but I would have used pure concentrated sulfuric acid instead of the hydrated magnesium sulfate solution with the distilled water. Handling this strong acid is risky if it splashes on you though. May be you are better off just buying another new battery. The consequences of a splash from sulfuric acid could be permanent. It is the strongest industrial acid out there. It could go through your cloths and into your skin in an accident. Always be careful if you mess with chemical agents, electricity or gasoline components. I usually stay away from them.
I once drained the 10% acid and replaced it with 20%. Fi ed the battery for three days. On the third day on the way home from work the battery exploded and blew the hood off of a 1982 ford Ltd. .

As long as the lead boards inside are still intact just replace the acid and your good to go however the lead boards are what causes a battery to fail because of the caustic nature of the acid and they have cut back on the amount of lead in the board's they start to warp and when they start to touch you get a bad or weak cell and then it will not hold a charge I get it how frustrating it is to have to replace your battery but the best trick to extending the life of your battery is use a battery tender if you are going to have your car parked for any amount of time over a couple days and keep it always fully charged I can make a battery last almost 10 years and I live in the worst environment there is for a battery the Arizona heat is very hard on batteries
I'm all about saving money and fixing things but really just get a new battery or used. It is interesting though.
So, you don't use new battery electrolyte / acid to refill the cells??
I will try this
Would you do this with a battery that's starting to act like it's losing its charge and not completely dead and another question is have you considered hydrogen peroxide to go in there and boil out the lead plates just questions no idea what I'm doing
Hydrogen peroxide is extremely dangerous if accidentally mixed with acid directly so I'd say no
Wow. I clean my bong the same way
How many people can do all this? Have the equipment? I buy a new battery when due. Thanks
Just solved the problem in my Chrysler 300.Went to mr tire and got a new battery.They are hard to install cause they are in the trunk under a mat.Several wires on the terminals and i broke one the last time so i let them install it.best 200 dollars I've ever spent.stay safe people cause another virus is coming.
So you're just saying after 2 days of charging it did not work. Now you want to charge it for another day. What about doing the load test on it after you get a voltage reading. Need to see that. Jim
I like to tinker so I'm gonna try this but how much is your time worth? Thanks for the video.
The battery lasted about 2 months, before I replaced it.
Do u know what ahydrometer is oh and maybe a load tester u just junked a good nattery
can't find follow up on this video. so what happened? how long did the revived battery last? thanks.
Anything yet from this man?
Need to put a load tester on and see if it really holds the load
Yes, this is "half baked" thing. The result is not convincing as later he admitted it that he have to buy new battery. just waste of time.
@@junkvista61 the battery had over 12V to start with.
Update video! ! Please and thank you bro !
How does the Epsom salts turn into acid like what was poured out
A Question can a guy reuse the old battery acid ? Run it through a Coffee filter ?
What would happen if you put white vinegar instead of Epsom salts into battery?
I paid 497 dollars for mobility scooter batteries in 2021 in Australia.
What a total wast of my time.
A friend of mine claims he has some ocean front property in Arizona for sale cheap.
Love that song!
Mr arrawhead garage may I ask you somthing does baking soda,salt, and water will work on any battery
I think so, this hack lasted a few months for me.... being in Phoenix Arizona USA where its 120F in the summers its hard on batteries.
Would have liked to have seen you load test it
I don’t think your wife is coming home, you probably killed her mixing chemicals in her cooking equipment 😂
i just add table spoon epsom saltzto each cell let set over night it desolves crud on plates
Don't wast your time. Clean the terminals on the battery and the car. charge the disconnected battery then load test. replace if it fails. it is what it is.
Work with agm?
Man you did an awesome job on that firebird, it looks like a Porsche now. Hahaha God bless
lol amazing what some bondo will do lol
So what did you do with the old battery acid?
My local county has a recycling location that takes just about anything you have to dispose of.
Something tells me he can do alot of non food related butter knife tricks 😂
Can I use iodized cooking table salt instead of Epsom salt???
Jude no you gotta use the epsom salt on this hack!
how does this chemical process repair Plate Area loss??
Let your wife cook the battery for dinner don’t forget the String Beans.
Where did you recycle the old acid?
The battery voltage without a load really tells you nothing. You need to measure the battery voltage under load. I highly recommend that people do not try to refurbish a car battery as there are so many ways to hurt yourself. I get it - they're expensive to replace - But so are your eyes! When plates in batteries wear out they're toast. Simple as that.
hello ......how are you doing??
You removed sulfuric acid from the battery but did not show the proper (safe) disposal of it. You "cleaned" the lead and lead oxide plates with baking soda (sodium bicarbonate), which would just neutralize any remaining acid and form the participating sodium sulfate. Then you supplied a rich solution of magnesium sulfate and charged the battery. The charging current would cause the magnesium to plate out on the negative battery plates. The chemistry of your "experiment" just doesn't work. Although you may have what appears to be a good voltage reading, that battery will have virtually no cranking power.
Please explain to all of us more, that problem with new liquid, how can man make acid that was first in battery, let's assume, there is no acid to buy
Epsom salt solution replaces the sulphuric acid??
Totally agree with you on that. Ph of magnesium sulphate is about 6, almost neutral.
I like your chemical analysis of this. I have seen inside and seen what happens to the lead , Just buy a new battery. People trying to restore old batteries is a waste of time.
I had the same thought on all the points you mentioned. As for the safe disposal part.....well that was simply tossing it on the ground outside.
