Wow. This is a trick I learned over 20 years ago when I was a HS/tech school/college student. I resurrected a few batteries this way back in the day - always amazed me how much more time it bought me to save for a new battery. In one case, the battery survived several more years of winter in Fairbanks, AK (-40*F was 'normal' in the winter there) and I wound up selling the truck with that battery still in it, working just fine.
There are several components to battery repairing. One plan I discovered that succeeds in merging these is the Magic Mender Wizard (google it if you're interested) definately the most useful info i've seen. Check out this unbelievable site.

That is great news Mark! This really works in most cases. If the battery has a shorted cell it won't but to rejuvenate and clear surface area to gold a charge again this works amazing. Thanks for sharing your experience!
Helpful video but I have a few issues, with terminology and safety. Battery acid is sulfuric not hydrochloric acid, hence the "sulfates". And ALWAYS pour acidic solutions into water, not the other way around. That way any splashback is more dilute and less likely to cause harm. Also, it's best to use enough baking soda until it stops fizzing, then dilute with water to neutralize acid.
Yes, battery acid is typically sulfuric acid. I think people get confused because batteries can off gas hydrogen gas which is extremely flammable AND can cause an explosion (think Hindenburg). This is why you never smoke near batteries and always connect the ground last ( AWAY from the battery carburetor/fuel-injection system).
Thanks for your input. I would like to know if I can just buy Sulfuric acid from the store and pour it instead of distilled water and the old acid from the battery? Thanks
One of the best videos--because you did it comprehensive and detailed--on refurbishing an old battery. Simply amazing. A new auto battery will run at least $ 140.00 plus sales tax in California, we're getting killed out here. That can feed me for two weeks and such. You bringing it back to peak level, nice and clean, ready to roll, means a lot. You do this 3 times over 10 years, you are talking 500 dollars in your pocket. Watched it twice. The details are everything. That cranking was "Beast Mode". # A D approved
@@AskTheCarExperts I'm working on recharging a similar battery for auto. Model 35/Size 35. Voltage above 12V, but charge is at 68%. Have to decide to I want to top off cell with distilled water or a quart of sulfuric acid. Want a robust end charge that holds its charge for a period of time. Steps are solid. Will apply. Looking forward to more good instructions on auto maintenance.
That is what i am doing and adding to that is to measure the voltage reading of each cell and must have the same reading: (+)-1st hole, 1-2, 2-3, 3-4, 4-5, 5-6 and 6-(-). 1st and last reading shall be added. This state tells you battery can be revive at slow charging process. Using acid tester tells a charge state of the battery.
Second time I tried this, it worked !!! Charged both my bus batteries, burped them at 225 amps 3 times for 6min each, cooled them between charging, final charge, 10 amp for 3 hrs, left 1.5 amp maint charger For over night, 13 volts , and full load Test ! Ripped that 3208 Cat diesel Right to life ! Gonna do more batteries for my buddies !
Wouldn't it be better to replace the Electrolyte with new? You can buy it at parts stores its fairly inexpensive. Its seems counterproductive to clean the battery then reuse the old stuff even if it is filtered. Just asking?
Yup! I put new electrolytes in my batteries. Price at the Auto Parts stores that stock it is $10.00 per 850 cc. BUT one container is only enough for 3 cells, so you will need two containers. So $20.00 for new juice.
Okay. I did this procedure on one of my vehicles when you put this video out, Dec of 2019. I was about to replace the battery when I saw the video. Anyway, over two months later and all is well with the battery. So again thank you for yet another valid no b/s instructional video. As I said before your videos were immensely helpful when I replaced my valve cover gasket, pccv system, water pump and thermostat, oil filter housing gasket... I could increase the list ad Infinitum. Seems like you disappeared for a while but sure glad you’re back.
Thank you for commenting! Great to hear the battery is still going strong! Between work and family health concerns I did not have any extra time. Glad to be able to provide helpful videos again! Great to hear you have found them helpful!
Question: whats the cold cranking amps, specific gravity and battery RESISTANCE prior and subsequent to any rejuvenation? Important tests which should be done.....
wouldn't hurt to stuff a piece of polyester at the bottom of the funnel to catch the bigger bits as well from the acid (cotton or any other organic compounds like coffee filters will dissolve)
I have actually got really good results by adding a little bit of washing machine liquid detergent in water and washing it with that and then 3X rinsing and now my battery works exactly like when it was new. If you ever put that black muddy liquid in a plastic bucket you will find later that you can not wash the bucket clean from it just with water but add a bit of detergent and it washes off 100% clean that's why I used it the 2nd time I reconditioned my battery and like I said it's now like 100% new or even better
Just saw this video, looks awesome. Wondering 2 years later is the battery still running strong? My battery is on the way out I think, it reads at 12.6V after driving and drops to about 12.4 to 12.38 overnight. I have it stuck on maintenance charging for a week hoping it will not die. I think I will have to do what you are doing this winter. Last year it always read 13.4V after the drive and drops to 12.6V over night. What is your over night reading on your battery?
Good video. FYI, @10:25 -- not exactly. The device that converts electrical energy to mechanical energy is for example the starter (or any other electric motor). Batteries convert chemical energy to electric potential.
Ouestion: would a high voltage DC (brief....max 1 second) PULSE put into a battery have a benefit. Would a REVERSE pulse de-sulfate the plates? The pulse HAS to be brief so as not to physically distort the plates. High voltage pulses have long been reported to rejuvenate dry cells. So would this be helpful or would ruin a typical automotive wet cell?
Thanks for the video. I watch through the whole video and I have one question. There is a mention of the battery is from 2014. How much of usage the battery had before it went bad? How may years of usage or how many miles? It would help to know the information to determine how long it take the battery to go bad as yours. Thanks.
Hi Michael, That is a great question that is hard to answer. There are many reasons why a battery can go bad. Usually in this case the battery failed from improper charging and discharging. As the battery is discharged too low it can create a coating on the surface area of the internal plates. This can be cleaned and re-activated using this method.
I want to try this on a 8V golf cart battery,which has one suspect/dead cell. It is usually charged together with the other 5 using a 48V charger. How can I recharge it on its own, having only a 6V/12V charger?
Very good 'IF' this battery can at least last a year and even better for longer. So how long did this battery last in this vehicle and hopefully it's still in there? Please respond, Thank You!! :D
Hi Patrick, I still have the battery and it is still cranking in the E46! This is definitely a low cost attempt with usually very good results barring any internal shorts in the battery.
@@AskTheCarExperts I am at present conducting the same experiment. But I am following your directions over other people direction. I think you have the most effective method.
I have watched several battery reviving you tube shows. Most say that you don't mix the acid. I was wondering if after the battery is flushed several times could you install new electrolyte?
Yes you can get fresh Sulfuric Acid. Used to be more commonly available. But it's is strong and very corrosive. It needs to be diluted with distilled water. I don't know the dilution off hand. But also a hydrometer inside a tool that looks like a big turkey baster is available to help measure the dilution. Useful if one keeps topping up with water only over years...it can show if it's too weak
First of all, why don't you take a high pressure pump and surge distilled water forcefully to the cells? Secondly, yes you can shake the case but its better to ALSO strike the case with a lump or smaller sledge hammer against a wood plank on the battery case. Of course, the pulses you're dire ting against the case have to be within sane limits. But carefully controlled sharp pulses have to lift sulfates which will not be dislodged by just "soft" shaking. Of course, you should seek expert advice before you try any technique.
Very interesting but down to the end I see you're using a funnel why don't you take one of your empty gallon containers instead of doing the battery and put it in an empty container where you can see it's clean and then put it in the battery just saying
Nope. Rain drops are usually created by nucleating around a seed particle - usually dust or grit. Unless desperate, better to use proper distilled water.
I did with my 2007 ford focus , I cleaned all the cells and used old acid and mixed up with baking soda. after i charged then I installed my car , It starts the car but after 15 minutes it says low battery. When i use radio and headlight high beam after 5 minutes battery signal show on the dash.
Hi Shafiq, The battery may not be the main cause. Check your charging system. You should have 13 to 14 volts from your alternator with the vehicle running. This should be able to me maintained under load from your lights and radio. It may be a bad alternator.
@@AskTheCarExperts thanks for replying me. I will rinse the acid again and clean all cells. I will do the same procedure again today. If give me the same problem then I will buy a new battery. After if shows again the low battery sign then I will change the alternator. I guess you right and also thought that the alternator is bad. I will clean all cells again for the last time.
@@shafiqshafiq4990 Before going through the battery process again use a boot meter set an DC voltage. State your car and check between the positive and negative cable. You should see 13 to 15 volts if the alternator is charging. If you do not see this the alternator is not charging. Hope this helps.
Its a gud tutorial, safety way to 're animate' a dying (sulfated') battery. Personally, I think it's a bit of a hit & miss effort. De better way is to 'maintain it' in de first place. Easier, n prolong sulfation build ups. Depending on battery usage, a sitting battery will eventually die even if new. Sulfation creep starts wen electrolyte solution added. I maintain a fairly used car battery by 'shock charging/ discharging' it every 6months n it will give U a reasonable 4-5yrs saving U heaps. Using a variable amps welder can do dis. Check dis method out from TH-cam but b careful as it's also dangerous if U r not careful.
You turn chemical energy into electrical energy to power an electric starter motor for your engine or your lights or the car. The alternator is supposed to recharge that battery once you get the car running the alternator has a capacitor and diodes so when you put the battery back in your car the capacitor once charged from the alternator the alternator capacitor sends it back to the battery
Really we dont know how the process turned out which would require letting that battery sit over night out side then reading the voltage prior to cranking vehicle. RIGHT?
Hello Andrew, I know the battery I performed this on was much stronger when used. But to test it you would need to charge it fully. Remove the surface charge and use a load tester to compare to the original reading.
😂 you don’t needed to saving that very old used Electrolytes Acid liquid.Just cleaning those acids holes with warm water and with baking soda to cleaning out of those batteries cells plates very well.Uses about 12 ounces of Epsom salts and about a jug of distilled water and mixing it togethernesses very well.Than pouring it back into those battery acids holes and uses a smart battery charger and settings it to repairing mode and charges that battery within 12-24 hrs.Your battery power should be restoring back to it about to that of 95-98%.That could saving you about $150-200 dollars depending cranking Amps and brands of batteries you’re buying..
You don't want to put baking soda in the battery. That neutralizes the acid. You can use distilled water and not re use the Electrolyte but it is good to start with some elecrolyte.
@@AskTheCarExperts The Epsom Salts and the distilled waters.Within 12-24 hrs minimum of electricity ⚡️ charging it.That liquid will be turning into new Electrolytes Acids liquids for the battery to uses..
Correct. I had a friend accidentally set off a trunk full of the outgassing from a bad battery when he was putting on the terminals. Full hair / eyebrow singed.
You can get dam near pure sulphuric acid for your pool. Open the bottle and it smokes. Especially on a humid day. It will explode if you add water to it. BAD move. Acid must be added to water. At 18-20 Molar strength you have a potential bomb if you add water into it.
Hi Jason, I do not have a load tester at home unfortunately. However, I did charge the battery before starting the procedure and it would not hold a charge due to the sulfates plates internally. After the cleaning it has been working great. Thanks for posting!
I'm not sure you had to go to all that trouble of flushing the battery. Just put a battery charger on it and charge the battery. I've had lots of batteries that go flat, but come to life with a charge. Often the alternator is bad and doesn't replenish the charge and eventually, the battery just runs out of gas so to speak.
Hello, Do you have a volt meter to check the current voltage of the battery apart from the charger? How long has the battery been dead? Did you try the charger on a different battery to make sure the issue is not the charger?
Hi Jeff, AGM batteries are glass cells that are sealed. If your battery does not have access to the acid via the ports in the battery you will not be able to do this procedure.
@@AskTheCarExperts I been zapping with the start feture on cen-tech battery charger. And it still won't hold it starts at about 7 amps and drops. So I'd say it's shot.
Newish batteries have much less lead in them ie thinner plates. Restoration of these is nigh on impossible. That's my observation having been in the motor trade. Very old batteries respond far better to restoration because they were built to a far spec and quality. Everything these days is to do with cost cutting materials down to the bare minimum
I boiled distilled water and mixed with baking soda and than i cleaned all the cells around 10 times. and after I filtered old chemical .and boiled 2 liters of distilled water mix with less than half pound of baking soda. and then I mix with old chemical which I filtered . ,and after I filled up all the cells. After i charged my battery 3 days and night . I check the voltage ,it comes 12.4 . when I check with charger clump with charging it comes 13 volt. as soon as i remove my charger clump the voltage drops from 13 to 12. what should I do now . should I add more baking soda or start the car with it. Can u please let me know. Thanks
First of all, what was the cold cranking current and volts prior AND after any procedure. After filtration, whats the specific gravity of the electrolyte? Does the filter material somehow chemically interact with electrolyte?
Baking soda neutralizes acid. Sulfuric, acetic, Muratic, hydriotic, all acid's. If you mix baking soda with the electrolyte from a battery you've successfully neutralized the acid. Making it impossible to charge Lead-acid battery's make electricity by chemical reaction.

I maintain a fairly used car battery by 'shock charging/ discharging' it every 6months n it will give U a reasonable 4-5yrs saving U heaps. Using a variable amps welder can do dis. Check dis method out from TH-cam but b careful as it's also dangerous if U r not careful.
Smart man Francis! Maintaining is WAY BETTER!
If I don’t have a battery charger, could I put it in my car and jump start it?
Hi Shawna, To charge the battery correctly you will need a charger. Using the car would take A VERY long time and it could strain the alternator.
You turn chemical energy into electrical energy to power an electric starter motor for your engine or your lights or the car. The alternator is supposed to recharge that battery once you get the car running the alternator has a capacitor and diodes so when you put the battery back in your car the capacitor once charged from the alternator the alternator capacitor sends it back to the battery
Really we dont know how the process turned out which would require letting that battery sit over night out side then reading the voltage prior to cranking vehicle. RIGHT?
Hello Andrew, I know the battery I performed this on was much stronger when used. But to test it you would need to charge it fully. Remove the surface charge and use a load tester to compare to the original reading.
😂 you don’t needed to saving that very old used Electrolytes Acid liquid.Just cleaning those acids holes with warm water and with baking soda to cleaning out of those batteries cells plates very well.Uses about 12 ounces of Epsom salts and about a jug of distilled water and mixing it togethernesses very well.Than pouring it back into those battery acids holes and uses a smart battery charger and settings it to repairing mode and charges that battery within 12-24 hrs.Your battery power should be restoring back to it about to that of 95-98%.That could saving you about $150-200 dollars depending cranking Amps and brands of batteries you’re buying..
You don't want to put baking soda in the battery. That neutralizes the acid. You can use distilled water and not re use the Electrolyte but it is good to start with some elecrolyte.
@@AskTheCarExperts The Epsom Salts and the distilled waters.Within 12-24 hrs minimum of electricity ⚡️ charging it.That liquid will be turning into new Electrolytes Acids liquids for the battery to uses..
@@Chu3505 Interesting, I have not looked into using Epson salts.
Battery acid is not explosive. Hydrogen gas is. But not the acid
Correct. I had a friend accidentally set off a trunk full of the outgassing from a bad battery when he was putting on the terminals. Full hair / eyebrow singed.
You can get dam near pure sulphuric acid for your pool. Open the bottle and it smokes. Especially on a humid day. It will explode if you add water to it. BAD move. Acid must be added to water. At 18-20 Molar strength you have a potential bomb if you add water into it.
Not even a load test?
How do you know if this even worked, or just a dead battery?
Hi Jason, I do not have a load tester at home unfortunately. However, I did charge the battery before starting the procedure and it would not hold a charge due to the sulfates plates internally. After the cleaning it has been working great. Thanks for posting!
So you published a video about reconditioning a battery and you do not own a $15 battery hydrometer???
how long u can drive.
Is sulfuric acid ( H2SO4 ) not hydrochloric acid ( HCL ) jus be carful.
Lol thanks! I have had a lot of people cakrify that for me 😀
I'm not sure you had to go to all that trouble of flushing the battery. Just put a battery charger on it and charge the battery. I've had lots of batteries that go flat, but come to life with a charge. Often the alternator is bad and doesn't replenish the charge and eventually, the battery just runs out of gas so to speak.
Why don't you use baking soda to clean out battery?
Baking soda neutralizes battery acid. You need the acid for electrolysis. I would not recommend putting this in your battery. Distilled water only.
What if i get no reading from battery, charger says Err, is it fixable or is it completely dead?
Hello, Do you have a volt meter to check the current voltage of the battery apart from the charger? How long has the battery been dead? Did you try the charger on a different battery to make sure the issue is not the charger?
We wesh by peur water
I have a battery that has a date of 12/21. Won't take a charge. It's an AGM. Can I do this procedure to it?
Hi Jeff, AGM batteries are glass cells that are sealed. If your battery does not have access to the acid via the ports in the battery you will not be able to do this procedure.
Nice job
Thanks! Great way to save some money and get some extra life out of a weak battery.
My battery was frozen, I was in a hurry to warm it up. Into the microwave she goes! 💥
LOL! If you do that I want to watch the video!
was your test bench a E36?
E46
Be very carful
Indeed! Gloves and safety glasses!
Your probably SOOL if you can't access my the cells right?
Hello, Unfortunately any sealed battery is not able to be rrcovered.
@@AskTheCarExperts I been zapping with the start feture on cen-tech battery charger. And it still won't hold it starts at about 7 amps and drops. So I'd say it's shot.
@@masterdomhowie871 Yup it sounds spent unfortunately. Weak batteries can also lead to failing alternators.
Newish batteries have much less lead in them ie thinner plates.
Restoration of these is nigh on impossible.
That's my observation having been in the motor trade.
Very old batteries respond far better to restoration because they were built to a far spec and quality.
Everything these days is to do with cost cutting materials down to the bare minimum
Your not wrong there Jules. It's all about cost cutting or raising prices on the little guy.
I boiled distilled water and mixed with baking soda and than i cleaned all the cells around 10 times. and after I filtered old chemical .and boiled 2 liters of distilled water mix with less than half pound of baking soda. and then I mix with old chemical which I filtered . ,and after I filled up all the cells. After i charged my battery 3 days and night . I check the voltage ,it comes 12.4 . when I check with charger clump with charging it comes 13 volt. as soon as i remove my charger clump the voltage drops from 13 to 12. what should I do now . should I add more baking soda or start the car with it. Can u please let me know. Thanks
If you put baking soda mix in the battery you most likely damaged it. At this point you will need to replace the battery.
First of all, what was the cold cranking current and volts prior AND after any procedure. After filtration, whats the specific gravity of the electrolyte? Does the filter material somehow chemically interact with electrolyte?
@@cindylawrence1515 after cold temperatures drops to 22 volts. I installed my car and car start bot voltage dropped to11
Baking soda neutralizes acid!
Baking soda neutralizes acid. Sulfuric, acetic, Muratic, hydriotic, all acid's. If you mix baking soda with the electrolyte from a battery you've successfully neutralized the acid. Making it impossible to charge
Lead-acid battery's make electricity by chemical reaction.
That car sounds like it needs some help. 😂
LOL Hi Costas, She does my friend! I still have the E46 3 series and I keep going back and forth between fixing it or parting her out. Buy she still has a lot of knowledge to give via more videos after my BMW N20 series. Please subscribe and I hope to talk to you again soon! If you get a chance check out my video on tips for fuel saving!
nice info
Sulphuric Acid....
Yes sulfuric :)
I know right😂
proof is in the pudding
Hi Tracy, Thanks for commenting. I used to do this on small lawn tractor batteries after they sat for the winter season and went dead. It also works on car batteries. The one in my BMW 3 series is still going strong :)
You should redo this video correctly sulfuric acid funnel use etc.
Thanks for the input James. It was a fun project. Maybe I will in the future but the info and steps are all valid and this really works!

Salfuric acid
LOL yup
Sulfuric acid. Not hydrochloric
LOL Yes Thank you.
