Yeah man I tried this exact trick with a battery a couple of years ago and it works just the same it would start the car it only lasted about 4 months it died again but if you're in a pinch that extra 4 months you can save up enough for a new battery

If you have multiple batteries, check to see which one is the best and still has all the cells connected. Desulfate that battery and drain the acid from the others. Remove water from the acid (look up how to). Then empty good battery. mix a 30% acid to 70% distilled water and fill up battery. Then charge with a good charger. This is your best option to fixing a battery besides completely rebuilding.

Need to desulfate the battery so it can be restored. There's a very simple circuit that I saw online and made before with just a capacitor and bridge diode and what it does is charge the battery with a very low amp, high AC voltage. It desulfates the battery, dissolves all accumulated sulfates from the plates. This takes a few days to properly restore the battery to its original state

this idea is great in a situation where someone cannot afford a new battery. experimentation like this is educating for people that like to experiment . very good in an emergency kudos to you guys.

I used to sell air cooled VW beetles during the gas crunch. Rebuild the engine, go over everything else and because 6 volt batteries were expensive, I'd empty them of electrolyte, fill them with water and shake the battery. Drain it again and turn it upside down on cement blocks and flush each cell with a garden hose. When the water ran clear, I'd let it drain upside down for an hour, fill with new electrolyte and charge at 5 amps for 24 hours. I installed the battery in the car and the customer never failed to get at least 9 months from the battery before it needed to be replaced. Cost in materials was about $3.

I'm not a into safety, but do have a "healthy" respect for gloves and glasses around rando batteries. Crank it up!

I love that you always try to motivate the viewers to do the experiments themself. I am so tired of this american "NEVER TRY THIS AT HOME, YOU WILL DIE" mentality. People of today are soo scared to do anything themself because of this crap. Remember that the greatest inventions were often done by people experimenting at home!

The great thing about lead-acid and AGM batteries is that they are 100% recyclable and it's a proven legacy product. Can't say that about lithium ion or other exotic batteries. Yes, Lithium ion batteries are much more powerful but, recycling is difficult and expensive and the technology is still full of problems (like catching fire).

I would have assumed that the baking soda would of just neutralized the acid, if you added more acid instead of water it probably would have worked even better

I've had success dropping one aspirin down each cell and topping off the water. a battery that charged to 50% and stopped, a day later it charged right up to 85% then another hour to 90%, then 2 more hours to hit 100%. had no problems with that battery near two years and sold it with the vehicle.

Good old baking soda and vinegar tricks. I've see others battery hack using epsom salt.

Things to consider before messing around and wasting time: If the battery rests at around 10.5-10.8V after you remove the charger, recycle the battery. It has a shorted cell and it will NEVER recover no matter what you do. If the battery is below 10v for a significant amount of time (over a year) , recycle it. It will never be good enough and you will waste your time. There are desulfator circuits and smart chargers that implement this method, however they are for a very light sulfation and it takes a lot of time to desulfate. This one was a great video. Desulfating batteries is always a patience and time consuming process. Putting them in the charger for a few hours it's just not going to cut it. If you left the battery overnight on a smart charger, they will probably start the car after a few spins. Problem is the voltage drops that low when cranking so there's not enough power left for the the ignition system to function properly(oversimplified) even in carburetor engines. If you have an EFI engine it's even worse because the voltage deeps so low that the ECU cannot function properly. If you could be so kind to do another video (if you have the time) and do the following: 1) Drain the acid into a container and filter it through some plastic cone filter (like the ones for paint) since the plain paper ones will dissolve and clog prematurely, 2) Fill the battery with distilled or deionized water and let it sit for day or two, 3) Purge the water out and refill with the old acid, and top it up with distilled water 4) Put the battery on dumb charger and let it charge overnight in medium amps, if it bubbles a lot reduce the current 5) Check the specific gravity (Special cheap tool with a bulb) of the electrolyte and and if lower add electrolyte (sulfuring acid solution 1,27 specific gravity). If its too high dilute with distilled water. 6) Switch to a smart charger and leave for a couple of days 7) Voila you can squeeze and couple of years out of the battery. Finally, the rule of the thumb in lead acids is the following, when the battery is charged all the sulfuric acid is in the electrolyte and the lead on the plates, and vice versa for a discharged one (oversimplified). In order to recover a battery fully to its original state after discharge, it will have to be under charging for the same amount it took it to discharge. For example: you left if for a week, you charge it for a week under the same rate. The last one is not practical , that's why car batteries fail early.

Pretty easy to predict what happens on this one when baking soda is commonly used to neutralize acids.

If you are successful at this point run the batteries through a few cycles for best results. Don't expect long term use though.

I understand baking soda soaks into pads and the plates inside. And you can't get it all out of battery. If baking soda is left inside it nuetralizes the acid, which you don't want. Best to not do baking soda and just try charging battery with arc welder set at 60 amps after topping it off with distilled and charge 5 minutes then off 10 minutes repeat 5 times. It should revive battery and desulphate plates without adding baking soda that might damage plates. If battery is really sulphated you might have to wash flush out battery insides with distilled water after dumping acid. Then refill with new acid and water. I'm pretty sure its very hard to get all the baking soda out of inside plates so I wouldn't recommend doing that.

Hey my name's Jordan Rider I'm from England and I love your videos there great entertainment thank you

One is supposed to charge a car battery at least for 24 hours to make sure all the cells are fully charged. This is because in the beginning the charging current is anywhere from 4 to 10 amps depending on the charger, but the charging current will drop gradually until the battery is fully charged. You can shock charge a car battery using over 100 amps for short period of time, but that charge is only preserved for short period of time and the battery will die within seconds.

Did you notice that when first starting the car the rpm would go down a little then keep going? this loading of the battery is warming it up . if you charge it again with HIGH amps to make the cells boil momenteraly it should get better(100-400 amps or use a 24 volt charger you could even use a DC welder but be carefull, so it begins to boil then rest for 15 minuts to cool down then repeat about 5 times, you dont want them to dry out just give them a good kick).

Lada cranking KZfaq Captions: [laughter]

Well, this wasn't the most exciting episode ever, but still useful and we learned some information that had practical implications in the real world (unlike 98.75% of Vlad's "scientific" experiments) 😆

You should make a diy electric Lada car that would be great entertainment thank you dude

You did most of the process correctly, but you forgot to add acid back in. Baking soda neutralizes the acid. It can't magically appear out of nowhere. It needs to be added back into the battery. As long as the plates aren't too damaged, it's possible to restore most of the capacity of the battery. You might get a couple more years out if it.

PRO TIP: You might want to reconsider how much you'll gain by doing this, depending on where you want to work on it. Last time I tried anything with a car battery, I ruined all my good clothes and the laminated floor. The acid is weak enough that you won't feel it on your skin right away or see things tear up right away, but still strong enough to destroy everything permanently. I ended up with damage worth the price of several new batteries and the same still dead battery. Now I just buy a new one every time.

From totally not working to somehow working for one day and then die again.

very professional my friend

No you can't. Trust me, tried many times on motorcycle acid batteries... Also you really need to wear some protection equipment during these tests...

Safety glasses

I'm rilly likeing that load cheaker haven't seen one like that before man

Just watched the fix battery ,have you tried the arc welder method??

You are a very good KZfaqr. ❤

The reaction your seeing is not because that cell was bad. It's natural for baking soda on battery acid. I have done this, you cannot revive a crumbling plate. If a battery sits resting at 11v you may be able to clean it out this way due to debris sitting at the bottom shorting out that cell. I got another 4-5 months out of it before it went fully out. Mine were being used for off grid power.

very interesting ! the baking soda dissolves the sulphate which damages the batteries (blocks the charge and the discharge).. just a pity that you do not show more closely the result of the disassembled blue battery.

Here in the US, battery prices have gone up and up over the last 3 years. This info could save a person $150.00, or so. Thanks.

How long will they last sitting on a shelf before they go dead after the battery is charged and would it keep a charge

If the battery plates are good you must drain the acid, fill with distilled water, and attempt to force the lead sulphate to reverse back into solution by charging at a high voltage. After doing this you must again drain the water and refill with acid to the proper level. Pain in the ass, usually doesn’t work amazing, because you get lead sulphate crystals, but it’s the only way. The problem is the reaction of the acid with lead forming pbs04 and you must reverse that reaction and try the acid back into solution to recover battery capacity. No chemical added will fix a sulfated battery

Hi. What did u use to fill batteries after cleaning the plates? New acid?

Does the "pour wine into the batter" thing help as an emergency jump start?

When I was a mechanic I had to empty an old battery, flush into it with our Karcher (not at full pression) then put new electrolyte and surprisingly see it working again. I put this battery on a tractor and it run it for 2 years. Can you try this?

Don't try this at home, try it at your friend's house instead, assuming they're still your friend after the last set of experiments... :P

all it is doing is washing out the old lead that fell of the plates. but if done right It will work like a new battery. but it is hard to get all the water out !!! And I did it without baking soda which kills the acid !!! I turn a riding mower battery from 300cca to 500cca when I was done !!! it took 15 washes to clean the loose lead out. And that battery is till going 5 yrs later. I still have it it's down to 250cca about now !!! but still starts cars and my riding mowers !!!

Maybe y’all could take an engine apart and put it outside for a while then put it back together with rusty parts. Then you could see how long it would run.

Need to measure the CCA before and after ❤

I have seen removing the caps and using a big change that has a 200 amp plus start function and running it for like 15 minutes at a time a couple of times with plenty of time for it to cool off Iit seemed to work for me

Would have been curious to see what simply draining the old electrolyte and adding new stuff would have done. I highly doubt that the baking soda actually did anything.

That next drift taxi sick

Magnesium sulphate Epsom salt’s works like a treat.

I'm not sure because he doesn't outright say it but, when done flushing with distilled water, what did he fill them up with exactly. For me its common sense to fill it with a mix of acid and distilled water. Maybe its so obvious for him to do so that he didn't mention it. Would a lead acid (calcium or not) even function with only distilled water ? Distilled water is a pretty bad conductor so results would be under what we expect if we filled them with a regular mix.

That Lada isn't going to start without a king lead

Yes what were the batteries refilled with?

I also call that a successful test!👌😂👍but them batteries looks like they’re from the 50s! Lol

My dog handling acid battery with no gloves on but a screwdriver 🤣🖤

Indestructible Lada!;-)

So cool!

Love you guys

Ive seen them used a welder to restore the battery

Lada submarine!

so throw baking soda and water in there then flush it with distilled water but what do you refill it with when you are charging it?

Right the voltage may come back but not the amp hour capacity never come back close to 100%

I've had a lot of luck by draining the battery and replacing the sulphuric acid from the hardware store. Only works with lead acid batteries and with the right concentration though.

Do we have an update on the bus build?

what else than lead and lead oxide would you have in there

Could you make a video about reviving dead battery BUT with using invertor smelter (this guy gives cca 18.5V)?? I've seen tons of videos.. it's simple you just fill it up with d.water (but NOT all the way to the top!) and give it 20-50Amps for about 3-4 hrs whilst checking the temp.. if the temp goes high, you let it cool and repeat.. 😉

what about epsom salt in distilled water, does that bring a dead battery back to life if the battery is on the charger for 24 hours? i have seen videos but not sure i believe them, the people say the distilled water needs to be warm and super saturated to the point it can not hold any more epsom salt.

This does work. However, the battery wont last for a long time. This would only be a temporary fix. The battery plates have been ate up by the battery acid. All the gunk has settled to bottom of the battery shorting out the cells. That's why the battery is referred to as having a dead cell.

I can smell those batteries from here 😆

11:35 the dizzy isn't connected to the coil there.

Please use some PPE!

Epsom salt / Magnesium sulphate works

I'm about to try this on my Mustang's car battery that keeps dying because I hardly drive it.

That is good to know, 😁👍

8:51 actually using a hammer and sickle

Baking soda cleans coroded battery terminals very well

Now do this same experiment with sulfuric acid. Bet the results would be much different and not spiked with unneeded sodium cations!

Wow awesome

Wonder if you can take lemon juice and revive it this way

Disodium EDTA is what you want. not baking soda.

You use the current from a welder to desulphicate a car battery.

9.6 volts under load is minimum battery voltage

Try with a dc welder..

Now this I have done before. You really don't want to use baking soda as it is a chemical; base and will neutralize the sulfuric acid that is used in a battery. To restore a battery, use Distilled water to flush the battery and rinse it out. This will need to be done to all of the gunk in the battery is gone (or almost gone). Then refill the battery with new sulfuric acid. To charge the battery, you will need to hook it in parallel with a charged battery so it will take a charge This is due to the fact that most chargers will not activate if the battery is below 9 volts.

Very interesting, I don't think I'll bother tho

Baking soda? That's one I've never heard. I've seen Epsom salts used to renew old batteries.

107% success rate! : )

Ruskys don't use eye protection at all

Put the coil wire on and it will probably start

They are using hand AND eye protection!!

Im surprised those batteries kept the starter cranking for interesting amount of times

That method works but it doesn’t really. As the Soda will neutralize anything that is acidic by rule, on top of lightly cleaning the oxidation on the lead plates. Meaning you will very likely clean it up just enough to help remove some of the shorts, improving voltage and capacity. But there is also no way to completely remove every little bit of soda even if you rinse the heck out of it, unless you comply disassemble and clean each plate individually. Meaning over a short period of a couple weeks to a couple months, without a complete disassembly when cleaning,, the tiny amount of residual soda will eventually neutralize the new electrolyte that was added. So really unless you are competent in assembly and have new plates and electrolytes, the soda method isn’t worth it.

What kind of testers that lol

"sexy ladies..." "...thailand" I dunno how to tell you this boys, but...

*Barking soda* works well on dogs too.

Too much trouble for a dodgy battery when a new one cost 80 dollars and last another 5 to 10 years

👍

its me or the coil cable to the distributor wasnt hooked up!

Am I the only one who noticed that the coil plug wire wasn't connected to the top of the distributor? That's probably why it wouldn't start

Reviving battery use epsom salt and water

Paint a car 🚗 with ballpoint pen ink

Messing up with acid without gloves or glasses. Tell me you are Slavic without telling me anything.

Please tell me the fluids didn't go down a drain AAAAAAA

Sorry battery was flat. But I'm here now
