- Can you recover a battery with Epsom Salt? Yes kinda, but how and why? Store batteries on concrete? Yes, it's fine.
Differences between deep cycle and regular cranking battery.
Why batteries explode and how to jump start a car.
This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries batery.repair and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!
Been in industry since I was a kid and no one has ever been able to explain to me why a deep cycle was "better", always just chirped that "Buy a deep cycle, they last longer!"
Suppose I could have googled it at some point in the last 10 years but waiting for you to explain it was easier. Thank you sir, always a pleasure.
I was told to NEVER use a deep cycle in a regular vehicle because the stress put on it shortens the life of a deep cycle. I agree now. I think its more the fact you wont get the cold cranking amps of a regular battery due to less panels producing electricity at a higher level. That and a deep cycle battery takes much longer to charge than a regular battery. What say you?
RC Hobbyist Extreme
100% score I think.
They are just different types for different purposes. You’d use both in a RV. One for cranking and the other one for idk everything else.
I guess you could use a deep cycle battery together with some super capacitors as an all purpose battery. The super caps would provide the cranking power.
You "can" use the lower crankingamps deepcycle batterys for car use, the just voltage sagg lower and geht tortured harder... If they last longer at this misuse case is unknow/up for testing by anyone.. At a higher premium price i will use the as intended rv supply battery and buy the cheaper noname car batteries anytime
The money difference is reserved for beer stashing in my mancave
TPfaffle in Australia we call any battery with some sort of structural support deep cycle. The idea is that the metallic portion of the battery will not get too thin and collapse or break apart as quickly if it is supported when the battery is at low charge....
So if you regularly run your battery below 75%-90% it is probably a good idea... if not they just cost more and should be used with the appropriate regulator
@@glenecollins Yep, and here I was thinking that AvE was just going to show us how to seal up the battery again and fill it up and send it out the door with a charge, got a little upset when he knifed it.
I love the Don't Panic mnemonic, I'll never forget that now. Good old Douglas Adams. This vijayo has also had the highest number of pauses to look up technical words, especially relating to granular structure of materials.
After working with batteries for 7 + years. Please douse your work station in baking soda (medium grit if possible). Don't let that invisible beast live on on all of your stuff. You'll have itchy wrists for weeks until you completely neutralize the acid on all of ypur stuff. My 2¢. Love your channel brother!
IF I have learnt one thing, its that Uncle Bumblefeck is not a chemist

HE a cook though!
Yet still more of a chemist than my HS chemistry teacher was.
I'm no chemist, but as a hobbyist electroplator, i love learning about chemistry. I feel like maybe the concept of the reactivity series of metals was missing here. Thoughts?
He does make some pretty good crystal meth hehehe
Chemist or not he has me thinking of turning some old batteries I have into downrigger balls.
It's funny how chemistry and metallurgy can be so much more interesting when it's *relevant*. Good job AvE, always learning something
I wish I could work around this dude for a few months. The playful banter and the fantastic information would benefit any one of us why guys.
Yup this dude is awesome
DAMN, son! Last time I heard such a rambling, fragmented explanation was when I returned from an overseas deployment to find my wife had bought a huge TV on a payment plan that amounted to around twice the cost of buying it for cash out the door. This video caused a flare-up of my PTSD and I'm now on a gurney in the ER with wires hooked to my man teats. Thanks alot.

How the fuck did you comment a week ago?
@Ryan Stephen Patreon gets you early access
@AvE I have shared this with some of our coworkers to use as training. It is a good informative video, and it lacks the "we know best" feel that you usually get in seminars or info dumps by battery salesmen. I work in the automotive industry, and I think this is the first time someone has explained internal current draw/internal short.
Cheers bud!
The internal soft short totally explains why one of my batteries, an Interstate coincidentally, would act like a normal battery for about 3-10 cranks and then suddenly act like it lost a couple volts. Oh wait, it had. I was getting barely any current from one of the cells after very short term usage, and I knew that was the case. Just really didn't know why.
@@arduinoversusevil2025 Cheers all around. A bit slow, in Norwegian time zone so 10*8-viking amounts to...beer.
@@802Garage
Nope. At least one cell had excessive hard sulphate crystals coating the lead plate. So only the exposed portion of the plate could exchange ions. This allowed that one cell to discharge very rapidly, increasing battery impedance.
@@avid0g Couldn't it be either or? That was more or less my original thought, but this seemed to explain it better. Interesting though.
AVE! You Had It right the fit time. (IN A BATTERY ONLY!) THE POSITIVE (+) IS THE CATHODE AND THE (-) IS THE ANODE. (IN A BATTERY ONLY!) LOVE YOUR VIDS BRO!
Would you care to walk through the thought process?
Way back batteries were housed in wood boxes with a thick tar painted inside. The wood dampened with acid would drain if left on the floor.
They used to rebuild them reusing the dampened box.
As a kid I watched this a couple times in my uncles shop.
I that's where the myth of leaving a battery on the floor/concrete will kill the battery. Back in the day it was true but no so with today's plastic cases
Thanks for bringing that up
and some were made from glass too werent they ? i'm not clued up on this kinda thing
@@jasonharrison25 If you battery is not clean, leaving it on the floor will still kill it. Electrolyte residue on the top and sides of the case creates an electrolytic path to ground, through the concrete floor.
I've seen it many times at work.
I've seen it cause a drain on batteries that were still installed in the equipment, by draining (electrically) to the frame of the lift.
Keeping the battery clean will prevent it.
@@fortj3 but that isn't really a function of placing it on the concrete. The discharge path is more likely to go from terminal to terminal if you have that much acid and corrosion on the battery. Also it would happen right on the vehicles battery tray too
@@yeezywesty3651 usually only the stationary ones like used in labs, etc. Those where made in jars and other glassware. Those are the only glass ones I can think of
Edit for more information. Also it was helpful as acid could be added as a means of "recharging" them as City provided power was rare back then, hence the reason for using batteries. They would just replace the acid until all of the plates where used up then replace them.
ive been cheating on you with this old tony .. there i said it, let it be known.. we can still be friends
Welp, if you're gonna buck off a side slice anyway; might as well be quality.
To be honest, Its only cause you got more important shit going on around the holidays than to post UA-cam vidjayohs and I've already seen literally all of your old content, and I mean every single video and I didnt know of tot until much more recently, though, thanks to you aswell, actually, come to think of it, most of the content I consume was first learned about from uncle bumblefuck.
This is strange, I've been bingewatching this old tony for the last week, i just discovered his channel, good quality content, reminds me of the time I've discovered uncle bumblefuck. Much respect for both of this guys.
It's not you, its me.
Look I don't wanna start a conspiracy or anything here, but, what if TOT and AvE are the same person? I mean think about it...
Has anyone ever actually seen This Old Tony and AvE's dick in the same vice together?
Sadly from my years of experimenting with lead acid batteries on my channel, the epsom salt doesnt really help desulfate it but instead acts as a stronger acid which makes the remaining working portion of the battery work harder.
1:21 actually this is becoming incorrect as technology has advanced. lithium batteries can be smaller and jump start a car, for instance look at those lithium jumper packs they sell. they are strong enough to weld with.
Furthermore regarding cost. a 115ah 12v battery only has about 35 useable Amp-Hours since peukert's law effects lead acid far worse when charging and discharging. so that 115ah battery has like 450 watt-hours of energy available at a reasonable discharge rate. meanwhile only twenty of Tesla's new 2170 cells could replace that, costing about 3$ each to produce now, means that would be a 60$ battery if lithium instead of 90$ for lead acid.
just FYI, thats why i've given up ever working with lead acid again. lithium has it beat in every metric now. just as long as you get the charging right. ^^b
Lead acid's benefit is not going into meltdown when improperly charged or discharged. The battery just gets worse and worse till you have to get another one. So the cells and battery have a better safety profile. Modern battery management makes up for that, but good, reliable, BMSes are expensive (you really want something that can interrupt full short circuit current)
@@RobertSzasz not going into meltdown? have you ever seen a lead acid battery explode? its easier to make a lead acid battery explode than a lithium one.
this is false, it isnt just from charging issues. lithium batteries are tested to extremes, and even some 18650s can handle 12 volts with just venting. its when a cell is punctured or shorts out internally that exponential deflegration happens. and you only get internet shorts naturally if you buy crappy cells.
if you short out a lead acid battery, you will get a bomb.
The only thing that does it for me (even though I have access to all the 18650s I want) is safety with Pb batteries.
And a crowbar circuit and a properly sized fuse (blows both at minimum charge and maximum) isn't as good as a big contactor but is acceptable for safety
those small lion booster packs don't deliver enough current to jump your car...you plug em in and they recharge your existing batteria. I found this out when trying to use on one of my junkers with a defunct battery.
I live in Epsom. We simply rinse batteries under the tap.
Tappy tap tap
Hey, I learned something! Finally, a clear explanation of the reasoning behind the order of operations when junk (an auto-correct from "jump" but Imma leave it) starting a vehicle!
tell the truth, it was Dewclaws fault
friggen dewclaw eh
its hard to trust a sparky, they've absorbed way too much voltage to make good decisions
You know what fixes an abnormally sulphated battery better than Epsom salt? Just giving it a charge until it's specific gravity stops improving, which could take a few days to 2 weeks. If the specific gravity never came back to it's rating you can give each cell a shot of 1.400 gravity sulfuric acid (50% acid) to break up the remaining sulphate on the plates. If you over watered the battery at any point and lost acid to an overflow you will have to acid correct more to get the best capacity possible back. Never ever go above nameplate gravity, you will destroy your plates with that kind of acid concentration.
The majority of batteries specific gravity rating at a full charge is going to be between 1.280 and 1.295. In case the battery doesn't have a data plate with that information, aim for 1.285.
My job is refurbishing industrial lead acid batteries, along with swapping batteries in lifts, repairing and configuring chargers. For us we load test a battery before giving it a pass. If a cell goes below 1.7v in our 6 hour rate test it's a fail, if the battery as a whole does not hit 80% capacity it's a fail. Though if it's just 1-3 cells that failed we'll probably just replace the cells, if it's more, we'll save it's good cells for a different battery. It's fun stuff, and I love the chemistry behind it
What can you do with batteries where someone was using tap water to refill them? The tap water seems to have caused the self-discharge to increase, and increased the gassing and vomited electrolyte out the vents. Should one charge until full, dump out contaminated electrolyte, and put in sulfuric acid of the proper concentration? Thanks for any help you can offer. Also, from your description, is sulfation just a problem of the electolyte leaking and then becoming too dilute through filling with distilled water?
@@gregorymalchuk272 Toss them off a tall bridge. They make a great splash, and you might knock some fish out.
@@gregorymalchuk272 The best way to avoid sulphation (UK spellings R us) is to recharge promptly, never let it go completely flat. Don't overcharge it either, mind you, or the positive plates turn to red crumbly stuff and eventually drop down.
I haven't had much success with batteries topped up a lot with hard water. I did get a bit more time changing the acid for 1.260 then a very slow charge, then adjusting acid SG after a few cycles, but to be honest once they are misbehaving it may be time to recycle the lead for new ones.
@@RupertReynolds1962 Yes, it also depends on why the battery is misbehaving. If it's old age or heavily abused it's better as scrap, but if it's under 5-7 years for industrial batteries and it's just been habitually undercharged, it may be recoverable for some more life. It's never like new, and buying new is better long term financially, but for some customers the price is right in the short term.
"It has an ortho.... it has a different f*****g thing." LOL. You talk just like my college Biology 101 teacher. He was a cattle rancher. Best science teacher ever.

Uncle AvE, your words, bigger words, and element abbreviations gave me a headache, a small but painful cerebral hemorrhage I'm afraid. I am throwing away my battery chargers and my collection of 8 yo batteries and replacing them all. I may never be able to look upon my swollen power storage devices with child like innocence as I used to. I hope you are happy now.
you just made my day even better , finished my last back shift for the week got home at 1 am , looked earlier nowt on so fannied about on face arse insulting people with some beers , ran out of people to insult , looked back and da da , the perfect day , gonna chug some cold ones and enjoy , thanks
Also, the H2/O2 offgasing only happens during charging, during discharge the H2 from the H2SO4 combines with the Os coming off the PbO2 and you get H2O. Reverse while charging.
i was a mechanic for 30 years and it that time i have seen a number of batteries go off. not to mention the damage to the vehicle and flying acid and lead and plastic projectiles,it makes one god damn hell of a bang.

Thank you for this video, as an Interstate dealer I have to explain these points daily. Most people just don't understand.
The anode/cathode depends if you have a battery or an electrolysis cell (i.e. recharging a battery). The anode is whichever electrode oxidation happens on. So in a battery the anode is the negative, in an electrolysis cell the anode is the positive.
Best description of lead acid batteries I have heard..Regards.
Ease of discharging has never been an issue however lasting power...

"it has a ortho............ A different fucking thing" best description ever
I was told in school that the reason we don't put batteries on a concrete floor (especially if it's cold) is that the concrete is colder than say, the greasy, grimy, wooden work bench. Since it's colder, it's gonna pull heat out of the battery, thereby making the battery colder. At best, this could cause the battery to be less efficient at starting the vehicle when we install it, at worst the battery electrolyte could freeze. Made sense to me at the time...
Oh yeah, the itty-bitty-titty-committee way to jump-start a vehicle (at least according to Haynes, for what that's worth.) 1. Place positive cable on dead battery positive. 2. Place other positive on good battery positive 3. Place negative cable on good battery negative 4. Place other negative cable on dead battery vehicle GROUND POINT. Every source I can find says GROUND POINT (not battery) on dead vehicle.
If you've got a vehicle with the battery in the trunk, under the rear seat, in the fender (seent it, replaced it), you're golden, just hook the cables up to your jumper points. However, if you're trying to find a good ground point for a vehicle with the battery under the hood I've found that exhaust manifolds or exhaust manifold fasteners, despite their rusty, crusty appearance are usually a good choice- typically clear of things that go boom, electronicals, and easy to reach. The oxygen sensor heater circuits on some older cars actually grounded out through the exhaust system. If you've got a front-wheel drive car, the studs for the struts are another good choice.
Something else I like to do when jumping a vehicle is to shut off every electrical circuit I can, especially if I'm giving somebody a jump. Radio, A/C, headlights, flashers, whatever. Just makes life easier for both parties. I also like to bring the speed of the booster vehicle up to typical highway cruising speed/noise, say 2,000 to 3,000 RPM depending on what sort of vehicle/engine you have to ensure that the alternator is putting out plenty of current.
You are right. It helps to rev up the engine of the donor vehicle a bit.
I actually Run Everything Lights,heat,radio . Makes the Alternator Push a Little Harder..
A few questions: 1) Do you drain the acid before adding Epsom Salts? 2) After treatment, do you add more acid or just water? 3) What if after treatment, you drain everything and get as much “schmoo” out, won’t that extend the battery life?
As usual, excellent video.
There are videos about replacing the acid with an epsom salt solution. I'm sure that's what he's talking about here. I have a battery with a migrating bad cell if I jar the battery. I suspect it has accumulated too much crap below the lead plates and there is a short there.
@@wellnesspathforme6236 couldn't the battery be turned upside down and flushed out and then put new acid in?
@@supermankent1041 Yes. I plan on trying some version of that. Someone said they knew a guy who used to steam clean the batteries upside down. I asked him exactly what that entailed, and hope to get an answer.
My dad's trick to fixing dead batteries was very reliable . Usually only one of the cells fail in a battery. We would drain out the dead cell and donate the acid from the other cells. Then top off all with distilled water and charge. This method has recovered all batteries with the exception of a few.
makes sense.
I'm citing this for a college paper I'm writing. Hopefully, my engineering professor has a good laugh if he even checks my work.
AvE, you remind me of my father's close friend Dennis he has the gift like you do to take something highly technical and make it understandable to even the layman. What a skill! 👍

Love all the vids. Stumbled on yours from watching the essential craftsman. Plumber and electronic engineer me loves them all. My father and 3 sons and I talk about them all the time. Well done each. Skookem start to finish. Keep on choochin.
When applying a battery charger to a battery in a car, or jump starting a car, connect the positive lead to the battery terminal first, then connect the negative lead to a good ground connection on the engine as far as possible from the battery. There are two reasons for this. As the spark is farther from any hydrogen gas it will not be as likely to cause an explosion. Also, while it is rare, it is possible for a fault to exist inside the battery or its battery terminals which could lead to an explosion. Being farther from the explosion is better than being directly in front of it. This is also a very good reason to use eye protection when connecting battery chargers or jump starting cars. Battery acid in one's eyes is no joking mater.
had a crazy Canadian move in next door when I was five. The next ten years where magic. Keep up the good work my Canadian friend. l love the show.
Ave, just to clarify as I think locking up the sulphate in the dump tray is not helpful. During charging the SO4 stored on the plates during discharge is recombined with H2 to make H2SO4 (sulphuric acid). In other words the SO4 is needed as part of the charging process and this is why a hydrometer is used to check the state of charge, it's checking the strength of the acid to the point where it does not rise anymore and so the plates are clean and all the sulphate is used up. Cheers, Andy. PS, hot glue can repair battery cases, how do I know? I've done it several times so this is not armchair theorist untried info.
Andy Reynolds i
Back around 1963, I came home on leave from the Air Force and my car battery died. A stone got under the battery and wore through the case and all of the Sulfuric acid leaked out. My dad used an old warped record and with a torch melted it and plugged the hole, added new acid and I was good to go.
@@Norm475 My last car was a 1984 MB 190D. When I bought it in 2013, the AC didn't work. It was very old so I just figured it had slowly leaked out but I did fear the possibility that it failed catastrophically. Eventually I got around to fixing it. During the nitrogen pressure test to try and locate the most extreme leaks first with soapy water and fix them, I found out where all the refrigerant went. The uppermost loop of the serpentine style condenser on the right side had been rubbing on the radiator mounting clip for years, and it had finally worn away into the tubing enough to rupture it. The clip has been pushed down far enough to just barely touch the side loop of the condenser. If it was pulled up or pushed down harder, it would not have been able to rub like that and it wouldn't have chewed that hole. The diesel engine made a fair bit of vibration and that model year had solid rubber motor mounts. Later years got much nicer hydraulic design mounts. I bet that was quite a scene when the hole ruptured. Big cloud of refrigerant and oil mist. 😸 Sadly, that would have been R12. Feel bad about the poor atmosphere. :'( But, since it was a spontaneous release of the charge, the equipment was still functional. I removed the old condenser, flushed the absolute hell out of the lines and evaporator and everything that I could, replaced the proper amount of ester oil (allowing later conversion to R134a) and replaced the condenser with a new one. Worked great! Hard to imagine how a rubber clip managed to chew through 1/16" of metal, but if we gaze upon the Grand Canyon and remember that the whole thing was carved slowly simply due to a flowing river of water, it becomes easier to understand. Rubber is softer than the copper of the condenser, but the sandy grit that constantly got between the 2 surfaces was much harder than copper. 😸 Like sandpaper!
This novel is completely irrelevant.

I had a battery failure several years ago that was probably one not recoverable with epsom salts. Most car batteries that I've had would just gradually get weaker, until they got too weak to start the engine. Not this one. I had no trouble with it, until one evening, after leaving the rent check at the landlord's office, I turned the key to start, and all the lights went out, and this battery would not produce enough pixies to light an instrument panel bulb. My guess is that an internal connector melted in two somewhere; it had probably been cracked or corroded. I managed to find someone to give me a jump, and drove home, with warning lights like a Christmas tree, and the tranny went into limp mode. Everything was fine after I replaced the battery the next day, but all the confusers in the car were very unhappy running on the alternator only, with no working battery in the circuit.
What you probably had was a bad connection to the battery. Terminal all crusty with white crud? As a mechanic i see it all the time, pull terminal knock the crud off, charge battery a bit and she's good as new with a little corrosive preventer on terminals.
Confusers don't like dirty pixies. You might want to get you alterationator checkumed up on. A failing rectumfryer can cause it to send out dirty pixies instead of clean pixies.
@@RingingResonance the alternator doesn't smooth it's output, i'm not sure how good it's voltage regulation is either. The battery in the vehicle acts like a giant capacitor even if it's not charging. Alternators aren't designed to output clean DC power, there's always a battery there to soak up the spikes and prevent dips, except when there's not >
Oh weedhopper, you just had an oxidized battery terminal connection or just a loose/weak connection to the battery post. Seen many times: vehicle cranks over fine, life is good. Shut off go grab a big gulp, go back to vehicle, try starting... nothing. Even if it looks good and no "green" icky schmoo on battery terminal, it's still a bad connection.
David Stearman i agree.
I used to do a sales route, and one fine day I left the customers shop and when I cranked the car, the batteria blew the fock up.
Big Badda Bang.
Walked into the convenience store and bought a box of Arm&Hammer, carefully placed all the shards back on top of the batt, and slowly and cranked it (It started!), carefully drove a mile to the next customer and bought one from him, then liberally dumped the soda around the engine compartment and then hosed it out.
The old Sam's Club sold Medallion batteries were stout items.
Had one back in the very late 80's into mid-late 90's that was used several times like a deep cycle (no charging system in a racecar) pulled and sat on the ground, poked by something and the hole sealed with that grand fixer, Liquid Nails, then regular tap water added, and it was used again in the racecar as a spare when the race deep cell was damaged in a wreck, then pulled and sat on the concrete for months, then used in the tow vehicle as a spare when its batt went badd.
Then I had a car that needed a bit extra to start, so I used it as a second battery to get enough cranking, and again it was pulled, set on the concrete and some months, maybe a year, later, it was again used as a temporary for a work truck, then I again used it for my sales car, where it blew up. Old rear drive Dodge Colts had the coil right next to the batt.
The "don't store batteries on concrete" old wive's tale is one example what really annoys me about people. They don't care to ask why you should or shouldn't do something. It is OK to follow something you are told to, if you think the person knows what they are talking about. But if you don't know WHY you do something, please don't spread that non-knowledge to other people.
What I find even worse is when people who in my opinion should know (electrician, plumber,... pretty much all trades) don't know why they are doing something. I like to ask about why certain things are done or must not be done. Half the time the answer is "because that's how we always do it".
That was the response I got 99 percent of the time in the Navy. We've done this since 1775 but no one knows why...

RIGHT! They think it will instantly suck the life from battery, like battery wouldn't explode getting discharged that fast.
Where the heck did this stupid myth come from in the first place?
I bought the biggest battery for my ztr at Tractor supply several years back. I lasted 2 years and went dead. I recovered it with Epsom salt and it went strong as ever 5 more years. It might still be good after I replace the corroded cable ends. I have also recovered automotive batteries with this method. I think battery manufacturers caught up to this a few years back, and started making sealed agm which you can not recover this way, and they are not a damn bit better than the old flooded lead acid either.
You can get into a sealed battery. Just because it says keep out don’t mean you can’t trespass. 😂
I did this for a science fair project at school several years ago and the battery still chooches to this day.
I just dump out the acid, flush with water while inverted several times, add new acid and equalize the battery and then test the capacity. If you have a battery that is 4.something volts after charging (instead of 6.something) then two banks of cells are shorted together. This could be sulfation. If you get 0 volts, one of the plate groups terminals is probably corroded away and the battery is NFG. Don't blast a small battery with 50 amps if it is failing because it may arc internally and spoil your day. Just equalize at 10 amps keep an eye on the voltage. If it jumps from 4+ to 6+ volts the sulfation bridge between two of the cell groups has been dissolved and the the battery should hold a charge again. If it's a deep cycle battery, it might have lots of lead left and be worth going to all this trouble.

I have a book called "Audell's book of practical electricity" it was originally written in the 1800's. In it they describe restoring an automotive battery but separating the top of the case from the bottom and physically scraping the sulfation off of the plates. I wonder why cases are "Sealed" today... Disposable battery.
The reason to connect to chassis is not quite as explained. The chance that the spark at the terminal will blow up the battery is almost nonexistent. However if something inside the battery is bad and sparks then you get boom. At least on chassis you are a a short perhaps life saving distance away when it goes. Also a good reason to connect to the dead battery vehicle first and the jumping vehicle second.
A very practical reason why you should connect to the chassis is not because of a minor chance of explosion, it's because if if you connect to the battery you are jumping the battery off as well as the vehicle. if you go to ground bypassing the battery then you are just jumping off the vehicle. This is especially true for vehicles that the batteries are almost toast and have been dead for a while.
@@ocp1669 How might that be different than attaching at the, just for argument's sake, upstream end of the terminal? I've never really noticed a difference while using a jump box or another vehicle. Kinda figured it's more like wiring in a second battery in parallel to the vehicle's original.
@@grantbaldwin-madison5267 I am just speaking from my experience, using a jump box when the battery is very dead, if you attach leads to pos/neg it doesn't spin the motor over as quickly and or barely if at all, moving to pos/ground it bypasses the battery so to speak and the engine spins over a lot quicker.
An old timer said something that stuck. "if you put the leads on the terminals you are jumping off the battery and the vehicle" Or at least something to that effect.
If the battery is just barely drained and hasn't been drained for a long period of time then it doesn't seem to matter as much.
From my experience the closer you can get to the starter the better the jump will be, and or the faster/longer the starter will be able to turn. When engines are out (turning engine over outside of the vehicle for compression test, etc), or I suspect the ignition switch may be an issue, I use a heavy duty remote starter to the signal lead on the starter to either the battery or a jump pack. The one I use I got from northern tool Model# W80586. Have tried the 12V remote starter switch from harbor freight, but with the kind of engines I deal with from time to time... the wires fried, after that I just upgraded to the heavy duty one and zero issues since.

You are thinking of cations and anions. Cations are positively charged ions, while anions are negatively charged ions. Cathodes on the other hand are negatively charged electrodes and anodes are positively charged electrodes.
@@bschilt3 I work with LEDs all the time, so I KNOW that the anode is positive. I was just about to reply how both you guys had it all backwards until I looked at this: "the anode is negative in a device that provides power, and positive in a device that consumes power".

i had no idea what you were talking about after a minute in. still liked it anyway
That's quite interesting. I wouldn't guess it would work based on solubility alone, since MgSO4 is several times more soluble than PbSO4. How long does it take to work, though? And do you have a guesstimate as to what capacity is restored, compared to a new battery?
(For those wondering) The mechanism is basically that the solid PbSO4 isn't actually always solid (if it's in contact with the solution), it's in a kinetic equilibrium so that there's a constant quantity of aqueous PbSO4 being solidified, and a constant quantity of solid PbSO4 being solubilized. Of course, PbSO4 being highly insoluble, these quantities are heavily biased towards solid PbSO4. When you add the Epson salt (MgSO4), this is quite soluble, but some solid is always being formed. When the solid is formed, it disturbs the kinect equilibrium (makes it more difficult for the solid PbSO4 to form), and the type of the MgSO4 crystals displaces the PbSO4 crystals, as AvE explained. There's also the ionic effect, by which the ions Pb2+ and SO4(2-), when in a solution with a bunch more ions added (like Mg2+) find it more difficult to attract each other, thus keeping them in solution, increasing the solubility of PbSO4. This is, however, not that significant in this case, because you are also adding more SO4(2-) with MgSO4, which subtracts from that effect.
Fun fact: NaCl (table salt) would also help the battery, concerning the disturbance of the kinect equilibrium, by ionic force alone - which would make PbSO4 more soluble. However, because it's so soluble the effect would be even less noticeable.
What??
Get a chemistry degree if you are confused and actually want to be able to follow along, dingbat.
Im glad to see the universal bench storage is working well in your shop. Mines very similar indeed.
OIL RIG: Oxidation Is Loss of electrons, reduction is gain
I used to make those lead plates in a battery factory. Hated the job, but the battery building process was interesting at least. And, that place had a pretty kick ass shop that I could play in on my lunch breaks.
The reason why you don't put your battery on concrete is because concrete is cold! Batteries do not like cold! Internal processes, electrons etc. Move slower! Same deal as a cold battery in winter time, its harder to crank! Its just good practice to keep it off the cold floor, maybe on a pallet or pieces of 2x4's.
If you sent a brief high current pulse into it, couldn't that revive the battery?
No, batteries love cold, if it's not freezing. Since it slows down the chemical processes the aging, corrosion also slows down.
You would make the most entertaining high school teacher in the history of entertaining high school teachers. Say'n.
I like me those absorbed glass mat batteries after having killed several smaller Motorsports flooded acid batteries. Lower cranking amps but survives my stupidity.
AvE.... Your my kind of people. Half the video I was nodding my head in agreement and the other half I was laughing my balls off at your commentary. Love it! Im a marine propulsion and power generation engineer. I go to sleep with boring commentary. You are not boring at all. Well done.
ur wife's been putting out too much ur slacking off... still a thumbs up. thanks for the laugh.
I buy lots of that exact battery. Desulfation of a starter battery is hard because of you attempt to pull off the sulfation destroys the plates quickly, I’ve had luck removing the acid, filling the battery with water, running a charger on it for a long time, changing the water again, charging s long time, draining the water, and refilling with fresh sulphuric acid.
This method helps it work because the pure water helps the sulfate come back into solution easier, and after repeated attempts you get enough out to have a useable battery again..... but it’s a waste of time in the end, I still just recycle most batteries unless they’re high dollar. I made a video a few years back demonstrating this technique, you can check it out if you’re interested. I’m not a UA-camr so making the video was really awkward for me
The anode is the negative pole in a battery.
Here is how I remember it. You put things like electrons into the cathode and take electrons from the anode. So + is cathode on battery while - is anode because you are taking electrons away from the -.
Pro tip:
I worked in a battery factory for 25 years. A little secret they don't want known is if you pour a tablespoon of baking soda in each cell of your battery it will bring it back to 90% of new capacity.
Really?? Baking soda?? Doesn't dat neutralise de sulfuric acid?
Easy way (for chemists) to remember anodes and cathodes: anode - oxidation, cathode - reduction. Unlike positive and negative signs, this is always the same for both batteries and electrolysis cells.
Do you have a mnemonic aid for that?
@@daithi007 Just remember vowels and consonants
'O'xidation - 'A'node

@@daithi007 Red-Cat and An Ox. But I just use Red-Cat (reduction at the cathode) and by virtue of being redox reaction the anode has to be an oxidation reaction.

Dear Uncle BumbleFuck, I'm deeply in love with you and want to have your baby! 😍
I was curious as to if it was possible to rebuild a lead-acid battery and watched a couple of vijeos, two of which discussed replacing the electrolyte with an aqueous Epsom salt solution, and another that said that was bullshit, the only way to de-sulphinate a battery was cycle it several times using a specific method causing the lead plates to expand and contract and hopefully slough off the sulfination. The Epsom salt guys didn't explain how their electrolyte was a superior replacement compared to all others. Then I came across this video and you explained the Epsom salt solution and how it worked. Praise be to St. Michael Valentine Smith! 🙏 Thank you for an educational as well as very amusing video that answered many of my questions!
I've had one of those buggers explode. Holy shits, it was horrible! Couldn't feel my right hand for days. "Stranger" week
I was doing the old reverse charging trick on a battery that I (very stupidishly) decided not to remove the caps first. It didn't explode but b y the morning it was round like a ball and the garage smelled like sulfur. The batter held a charge of negative 13.3 volts but I ended up recycling it anyways because it wouldn't fit in anything and tended to want to roll away when in use.
Same thing happened to me trying to start a truck at work POW! Sounded like a quarter stick going off thankfully the hood was closed!
I see what you did there. Like a Stranger. He he.
Ave, I've worked in shops for years. There are two reasons not to put a battery on the ground. 1) A battery on the concrete will freeze more easily, if near dead of course. 2) If you are charing it and it bubbles over it can short out, and also cause an environmental hazard.
Plus, who wants to pick up a 10-40 lbs batter off of the floor? It's so much easier to get it off of a shelf. ;P
This is the first I've heard of this trick to get a bad battery working again. I may have to try it to see if it actually works.
Someone should make jumper cables with a big hefty knife switch in the middle.
I've thought about adding a big, beefy rotary drum switch to my jumper cables, but the switch costs more than I'm willing to spend on a mod for my cables.
fortj3 eBay has battery disconnect switches for cheap who knows if they will melt or not! I know when jumping large equipment every miliohm in that cable counts so that might be an issue! I have used 3 sets of cables between the two batteries in two large diesel trucks to get one started before! And these where hefty cables 2 gauge. Guess it depends on what you regularly jump!
Batteries blow up BIG.
On a 1000A group 31 batt our MoCanique cut a melted post off & drilled & tapped it for a semi stud post. Hooked to another batt of same in 24v for a JD544C loader. Worked great for a day or so then one cold morn it went raw raw raw BOOM. Battery Less than 3' from my back w/no back glass in loader. Thank God the loader had it's battery covers. Blew that Sumbich to pieces. I will never forget that day.

🤣😂😂 I love this guy! My edit is, I have never heard this guy before Jan. 2 2024.

I have forklift batteries that need addressed (trying to help a friend). This guy seems to be worth a serious investigation of his other videos.
My old diesel teacher back in the day always told us to blow across the top of the battery before connecting anything to it to blow away the hydrogen gas
Hydrogen gas is formed while charging the battery with a lot of current. So if you charge the batterie and then connect something afterwards that might be a good idea. If the battery was just sitting around before being connected, no point.
Hey I mean it's a half second to blow across the top of it and a bit of security that it wont blow up 😂
@@Hellsslave666 Yes when charging a battery and you are done always unplug the charger before you take the alligator clips off the battery so there will be no spark and resultant KABLOOEY.
Thanks for this video. I had a car battery that had been sitting dead for a full year. Wouldn't take any kind of charge. Gave it a teaspoon of Epsom salt per cell and in 20 minutes the internal resistance had plummeted. Now it holds 10 amp-hours of charge again. That's a pretty cheap fix for an expensive item.
