- A SIMPLE explanation for how a Lead Acid Battery works. This tutorial covers the working principle of a Lead Acid Battery and how it is constructed. You can learn more about Lead Acid Batteries here: www.electrical...
The storage battery or secondary battery is such a battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as and when required. The conversion of electrical energy into chemical energy by applying external electrical source is known as charging of the battery. Whereas conversion of chemical energy into electrical energy for supplying the external load is known as discharging of the secondary battery.
During charging of the battery, current is passed through it which causes some chemical changes inside the battery. This chemical changes absorb energy during their formation.
When the battery is connected to the external load, the chemical changes take place in the reverse direction, during which the absorbed energy is released as electrical energy and supplied to the load.
Now we will try to understand the principle working of lead-acid battery and for that, we will first discuss about lead-acid battery which is very commonly used as storage battery or secondary battery.

3:44 shouldn't there be 2H₂O instead of 2H₂ in the reactants.
*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!*
Who needs drugs when you can learn about how amazing batteries are !! WOW !!!
Exactly 😉
What??
cause learning about batteries while on drugs is next level.
Maybe I wanna learn about batteries while on drugs
But I didn't get this
Probably i Will watch it later
You are a life saver!!
The explanation was so easy to understand
After watching a lot of videos , I got the idea clearly from here. Thank you very much
Crisp, clear, no nonsense info vid. Thank you.
You have made a beautiful, Crisp and informative vedio. ThanQ have a great day
After 6 year is your acount alive
guyz i am not crticising these people infact their content is really great and useful. it is pretty simple the article link in the description is even more useful...
just to correct one mistake i think that at 3:39 it is pbso4 plus 2h2o not only 2h2.
i think so, let me know if i am wrong
This is quite comprehensive and clear. Thank you.
thank u very much...
Thanks, S. Ghosh, for a terrifically succinct explanation of the discharging and charging process.
Very good explanation thanks from Pakistan
👍 Very simple, very clear, very easy to understand. BIG thank you 👌😉
the chemical reaction diagram shown in 3:42 does not add up.
8 oxygen on the left side. 10 oxygen on the right.
Equation mistake, 2H2O should have been there instead of 2H2
Can you count? Did you mean to say 8 on the left and 6 ( not 10) on the right?
@@alchemy1 You seem to be the one in the wrong!
@@sudersan2k7 Right!
It's understanding is vary easy😊😊
Finally, an easy explanation to understand..
Very nicely naratted about about secondary cell
So in your cell, negative plates are hooked together and positive plates are hooked together and then in the next cell I assume the end of each positive are hooked to the negative of that cell and the end of the negative of the first cell plates to the positive of the next so to add up the voltage.
At 1: 20-time frame in your video tell me why would SO4 -2 move towards Pb electrode if that electrode wasn't positive in the first place or provide some positive ion to attract the SO4-2. What is up with that and why is no one catching it. If you manage to explain it, I suggest to explain it really good. So your understanding makes sense to you and to me hopefully. Thank you.
Lead(IV) oxide, commonly called lead dioxide or plumbic oxide or anhydrous plumbic acid (sometimes wrongly called lead peroxide,) is a chemical compound with the formula PbO2. It is an oxide where lead is in an oxidation state of +4; bond type is predominantly covalent.
*The skill that some people have just absolutely amazes me*
The major problem of battery failed is we can not charge battery in a perfect solution. It means every time we charge battery and some PbSO4 does not be removed 100% from Pb plates. So PbSO4 accumulated to cause high internal resistance. The high resistance will make the charge voltage increase fast but battery does not complete the charge process. Finally, the battery capacity runoff.
So how to reduce internal resistance by using a perfect charger is what I am doing now. We already work with golf club to repair the failed battery of golf cart. It works as the way to protect environment.
Edward Chen hi sir, any update on this innovation of yours??? This would be great to minimize millions of batteries to be disposed worldwide in a given time especially if not done correctly.
@@rjsalcedoiii647 I understand your point but there is about a 95% plus recycle rate. Lead Acid batteries are not disposed of in the usual sense.
Please make a video on HTLS( High tension Low sag ) conductor. Used in transmisson line.
So much easy and helpful information i have ever seen💚
saved my life
Contextualized approach to explain how lead batteries Works
Thanks for upgrading my knowledge
very good video sir its help to improve my concepts thanks so much
Comprehensive and a great learning asset.
So you are starting your video to show what happens chemically to an already charged battery as you discharge it.
What is a charged battery? "(i.e. a charged battery is a battery that has inequality of electrons in the terminals. The side with more electrons is negative and the side with less is positive).
Therefore you are saying that PbO2 is a positive Ion and Pb a negative Ion?
You can not put a load to the discharged battery, you can but you won't get anywhere.
Which means a charged battery has PbO2 in the positive electrode and Pb in the negative electrode. And as it discharges both electrodes gradually become PbSO4 and once it reaches to that state completely you got a dead battery.
So when you begin to charge it again. You turn one of the PbSO4 back to PbO2 and the other to Pb.
Since both electrodes are pretty much the same in a state of discharge the reason the negative electrode becomes negative is that you put the negative terminal of the charger to it.
So in a nutshell. The charged battery has PbO2 in its positive terminal and Pb in its negative terminals.
And in a discharged battery both terminals becomes PbSO4.
Right?
So you are not creating an imbalance of electrons in the terminals as you are discharging because you are clearly helping remove the imbalance and move the battery towards becoming dead (i.e. increasing entropy) but you say the opposite that you create an inequality of electrons in the electrodes in your website and I copy and paste it here; " As H+ ions take electrons from PbO2 plate and SO4 − − ions give electrons to Pb plate, there would be an inequality of electrons between these two plates"
Nice and simple.
Well 'putted'. Thanks
😂😭
awesome explained ..........
Who is watching in 2023 😂🤩
I watched twice
Ofc me😂😂😂😂
2024 bhai
2024
In 2024😂😂
Basically it's not lead peroxide since o2 it is dioxide.Also in 3:36 equation instead of 2H2 there will be 2H2O .Please don't upload such kind of videos first study properly,verify and then upload.Refer en.wikipedia.org/wiki/Lead%E2%80%93acid_battery
Ur an fucking idiot lmao
sr ur explanation was suprbbb😊😊😊😊
Thank you for your kind words! Happy to hear you found it helpful :)
Perfect explanation
The Lead acid content and relation with that of the compounds and non compounds are good, since the said compounds and non compounds can be controlled/adjusted to be cleaner, safe as well as healthier, for them to be as efficient, durable and long lasting since it is recyclable/environment friendly, 2022 onwards.
Great Video!! Keep it up.. Relax and grow..
Props to whoever came here to learn.
time saving concept enhancing and full of usefull material wow
Thanks for good explanation 👍
If overfilled with distilled water and caused huge amount of the electrolyte to be drained, should sulphuric acid be added or the charging process will auto equalise the acid concentration?
The thing is that during discharging, the sulphuric acid is in the form of PbSO4, attached or sticked to the electrodes. However when being charged, the PbSO4 is broken down to Pb metal and SO4 ions, which react with 2H+ to form H2SO4.
Thanks for uploading this type of define
Last equation in the video is not correct..instead of 2H20 it is mentioned as 2H2
For this useful video i subscribe and put like. I was waiting for good explanation of the lead batteries
It helped me a lot
Very good practice
thank you so much for this great explication
No worries Soufiane! Happy to hear it helped 🙂
you are great man sir
You are too kind sir! 😁
Thanku sir
Ur teaching is very us full in my studies.........
Thanks a lot sir
God bless u sir
wait lead peroxide? don't you mean lead Dioxide? I thought peroxide was associated with organic chemistry :s and this is an ionic bond
it is lead dioxide
first sentence: en.wikipedia.org/wiki/Lead_dioxide
Tq .. it's really appreciable..
Who is from 2024
Great explanation, thank you
led per oxide?
shouldn't it be just led oxide?
Yes, it should be Lead(IV) Oxide. It is not "lead peroxide" as was mentioned in the video at 0:39.
great video, could you extend it a bit by explaining how a charging circuit may work. im trying to make a good charger for the lead acid battery. I was thinking about using a microcontroller.
😅😅😅
Suresh Pandya I absolutely understand about the electron flow. When your in chemistry and physics realm you use the fact that the elections flow from negative to positive but when you get into the world of electrical schematics conventional current is used exclusively. It's just ridiculous confusing otherwise.
Who are here in 2024😂?
it helped in my science exhibition..
It s very useful.thank you😊😊😊
Best Video!Thanks
great explanation! thanq
Sealed cover is necessary or open battery also functions same?
Nice
It's good
so nice and helpful
I was confused when you said electrons move from anode to cathode. I thought they go the other way. They are negative and attracted to positive. Thoughts? Clarification?
On anode there are oxidation, when on cathode there are reduction. From an oxidation you get electrons flowing in a wire (or sth) to a cathode where they are involved into reduction. By the time of they travel, they are used to do electric work. And while you are charging battery you are making the whole situation reverse; electrons from your external source of current are reducing the oxidated form of lead to its REDUCED FORM (PbSO4 => Pb), and on the other side you have SO4 2- ion that is giving its 2 electron to a H+ ions, and then (as radical) reacting with PbSO4 to return lead to its OXIDATED FORM (PbSO4 => PbO2). So while charging you are just reducing the oxidated form and oxidating the reduced form, so you can return to a starting point. The thing is that in PbSO4 you have lead on +II oxidation state, and it can be reduced (to 0: Pb II SO4 --> Pb 0) or oxidated as well (to IV: Pb II SO4 --> Pb IV O2) which is giving possibility to just reverse process and make battery charged again. I hope that you understand :D
@@drewniak2094 Thanks for your effort to teach your content! I’m printing this for reference.
@@drewniak2094 thank you.
tnx sir it was very useful
Error. direction of current flow seems wrong. Negative to positive.
+Eric jones Yes, the electrons actually flow from the negative, but it's just electric convention to show the flow from the positive.
and what on tarnation mother earth is the meaning of this bloody mushroom cloud electric convention in simple terms?
Eric Jones was actually right. I see what he was saying now. In the animation, electrons are showing flowing from the positive terminal to the negative, but electrons actually do flow from the negative terminal to the positive.
Basically, centuries ago when scientists were studying electricity, they didn't understand the quantum physics of what was actually causing it, but they knew there new there were opposing "charges" that attracted or repelled each other. They named one negative and one positive.
But quantum physicists decided to call the electron's charge as "negative". So the thing that is actually moving in an electric current is "negative". So it confuses people that are new to learning about electricity because you'd intuitively imagine electrons shooting out of the "positive" terminal. And many electrical diagrams actually diagram it that way, even though it doesn't match the physics.
its becoz crt direction is always opposite to electron direction... (convention)
Thanks
so nicely explained sir , thank you
many thanks, very helpful.
Very nice explained :) Is not clear to me what happens during overcharging from this ecuations.
thanks. excellent explaination
Well sorry, but your concepts are wrong. Because during charging the battery, the terminals of the electrodes are changed, i.e if during discharging, anode is negative and cathode is positive ,then during charging the battery, anode is positive and cathode is negative , in order to reverse redox reactions happening during discharging of battery.
Thank u sir
Thank you for clearing my doubts..
what is the reaction of lead acid battery when discharging with H2So4
Thank you
No problem! Thank you for watching Suri :)
@@electrical4you what is your number
thanks
I think attack is wrong term instead of wanting to reach equilibrium ... but still coreect tnx for the vid
What happen if we add H2SO4 to the cell battery when the electrolyte liquid got drained? Will it damage? Or, should we just add the demineralized water?
is it possible to remove acid and water (keep it dry) from the lead acid battery after full charging.. to keep the battery in good condition for longtime.. as after full charge negative plate will be lead and positive plate will be PbO2.. and after longtiime .. we will add acid and distilled water in 1:3 ratio to start using the lead acid battery.. pls answer..
very good.....
awesome ! thanks a lot..
Who’s watching it in 2024????
For Sealed Lead Acid battery, there are a lot gas come out during charging but why the Chemical equation doesn't show that?
អរគុណThank
The equation (time = 3:39) has an error! An O2 molecule appears out of nowhere (on one side of the equation we have 8 oxygen, while on the other side we have 10 oxygen)...
Appreciable. Yes.. I do!😀
Wait...SO4 gives an electron to Pb, creating an overall negative charge. Yet, the electron flow seems to stem from PbO2 at 2:24. Why? Shouldn't it be the other way?
Daniel Smith Flow of current is opposite to the flow of elctrons
conventional current , they invented that silly notation to confuse people didn't they? -_-
Hmmm...if there are more negative electrons on the Pb plate, wouldn't current flow the other way?
Listen carefully starting at 2:35. "connect LEAD SULFATE COVERED LEAD PEROXIDE PLATE to a positive terminal to an external DC source and LEAD PEROXIDE COVERED LEAD PLATE with the negative terminal of an outside DC source. What are you saying, man? I have listened to what you actually said 6 times. Listen to your own self. Which plate is which my man ( which one is LEAD PEROXIDE LEAD PLATE and no sulfate)? IS THERE SOME THIRD PLATE SOMEWHERE I HAVE MISSED?
I assume the first one, your " LEAD SULFATE COVERED LEAD PEROXIDE PLATE" is the one on the left of your video with the + sign on it.
Watching your video I label the left electrode as Cathode and it is LEAD PEROXIDE PLATE COVERED WITH LEAD SULFATE. The right electrode as the Anode and I describe it as LEAD PLATE COVERED WITH LEAD SULFATE.
If all these people actually watching and listening to this video doesn't get this, it shows that most human beings are gone in the head. Can anybody please tell me if I am hearing things and it is me for god's sake who doesn't make sense any sense.
Good
Who is watch video in 2024😂
Thanks.....🤘🤘
10 year in video now in 2024
pardon me, I got confused since this is different from my textbook and other websites :( I got extremely perplexed when you said that SO4 GIVES electrons when it doesn't, since its oxidation potential is lower than that of lead & when in fact the pure lead sacrificial anode is what does give electrons
Yes, I have recognized some mistakes too.
High amps are created by the sulfuric acid correct?
There is something mysterious i could not understand about the charges on the plates
thank you
Awesome.
