How a Car Battery Works

- Here's how the conventional lead-acid liquid cell car battery works.
The purpose of a car battery is to provide electricity to start the engine, spark for ignition and to power the lighting and electrical systems on the car. Once the car is started, the alternator takes over major electrical duties by keeping the battery topped off at full charge.
The battery is comprised of 6 cells, each of which have 8 plates inside. Four of the lead plates are positively charged, and are coated in a lead paste, and the other four are negatively charged and are coated with lead oxide paste. The plates are interlined with each, though protected from touching each other, separated by their own individual pouches.
The entire lead-plate assembly is encased in sulfuric acid, which provides sulfate for the lead and lead oxide to react to. The result is the emission of free electronics, which flow through each plate causing a current. The flow of electrons create electrical energy when a resistance or load is placed across the battery's terminal.
In this video a Type 24F battery is safely drained, neutralized, cut open and examined. The plastic top is plastic welded on, with factory fill ports at the top. With the top ground off, the 6 individual cells can be seen, with a lead conductor wiring all the negative plates, and another wiring all the positive plates together, leading out to the battery lugs or terminals.
Safety warning: Use protective equipment when cutting open batteries. Sulfuric acid is extremely corrosive to skin and other objects. Have baking soda and water nearby to neutralize any spills and work outdoors to vent harmful gases that may evaporate from the solution. Lead is also very poisonous, use gloves and a toothbrush when handling.

"...my wife's toothbrush, my brother's old trousers..." 😂😂😂
Hey I gotta use what I find right 👍
You have a great knack for teaching and keeping it entertaining and enjoyable. Love how you use other people's stuff (OPS) to clean and point out the interesting things.
I watch to understand how things work and your antics make it fun to learn!
Thanks very much for the feedback
I enjoy doing these videos
@@speedkar99 HOW DARE YOU!!!!! hee hee lol
A difference in cheaper vs more expensive batteries would be awesome
That would be a great comparison if I got my hands in some OE and aftermarket batteries
I know, I have opened them. I can write my experience here.
Quality batteries have pure lead plates, while inferior batteries have impure lead plates. Both of these look same when they are brand new but after a bit of usage, inferior battery plates start flaking off. Sometimes very bad quality batteries don't even have nets (separators) to prevent shorting between plates.
And you can measure weight of the batteries, good quality batteries are heavier than inferior ones, but sometimes inferior battery manufacturers add alloys to make their batteries even heavier.
I live in India, and I have used and opened up both kinds of batteries. Sadly I couldn't shoot video because my hands were messy and I had no one else to shoot for me.
the battery you showed us was the old fashioned immersed cells... the newer AGM use an acid gel on fiber glass mats...
Interesting part is on the control side... nowadays software controled charge uses a "battery sensor" mounted on the negative terminal to sense:
internal temperature,
overall batt voltage,
current using a calibrated shunt
(all of this for 12V lead-acid battery chemistry)
Is it a good idea to use a small lithium battery?
After this video I started using a toothbrush to look at plans, point at people, clean everything and play guitar. Handy tool
It sure is. I'd like to see the guitar video
just found your vids. Love your humor and wicked smaat science tutorials. Science! You have a sub brother
Thanks very much, feel free to share!
Closing in on 100K. You just might do it! Keep up the great vids Speedy!
Thanks ! Looking forward to it
Awesome. A video about how power folding mirrors work would be great.
Good idea...thanks
Wonderful video and an excellent overview of how it all works. Looking forward to more.
Thanks. I'm hoping for more to come too
Belated congratulations sir, hearing it for the first time that you're using your wife's toothbrush, it is safe to assume you have recently married, happy for two.
Thanks ... Now I got a whole new pile of resources to steal from 🤣
So I take it you done with your project junkyard car and it's stripped pieces and works are back in the graveyard. You really enjoyed that stripping learning experience, it's still the best way to learn.
Yep it was quite the learning experience. I want to do it again next year. What kind of car do you think I should do next?
Choose a common car that most people own, so they have a reason to watch your videos. Ford, Mazda, vw, BMW. A german car may be interesting if it is common, you like electronics, as long as you have the temperament to tolerate having to buy and use fancy (stupid) torx and e-sockets, and curse all day at that german!
I love ur improvised pointing tool.
Yep gotta use what I got!
An auto mechanic savant who uses other family members old underwear and hygiene products sounds like a Hollywood movie script...
Haha I'm a movie mystery
Why
Something I don't want to mess with. But very satisfied my curiosity is over about this one 😏
Using wife's toothbrush instead brothers. Nice because it's toxic.
Exactly 😏
@speedkar99's brother HAHAHA.
@speedkar99's brother
Your username 🤣🤣
You can take a plastic hanger (but it needs to be the one that looks like the red hanger logo) and get some wire cutters and cut the hanger on the two bottom ends
Thanks, Rick Moranis.
Great to learn
New pink brush. Nice
Yay new gloves and toothbrush
@@speedkar99 send me your old brushes. I need to wash out my neighbors kids mouth. He uses toilet language.
انا طيب القلب ونصوح شكرا سلام
"Ok, to work on a battery you must have a pair of safety glasses, protective gooves, my wife's toothbrush.."
That's so specific! 😂
Which have many plates? Positive plates or Negative plates
The toothbrush bit had me cracking up.
I really liked your videos please upload more don't give long breaks
Thanks for the suggestion. I'll try to keep them coming...it's winter here now!
For the negative plates, what happens to the lead sulfate and water that is produced? Another great video BTW. Thank you.
Recharging reverses the reaction
speedkar99 ah thanks!
Excellent and informative video! Thank you sir ^_^
You are welcome
great video as usual, very informative..
I don't get it why people does not subscribe to this channel, this channel deserve more than current subscriber number.
I agree. Please share with your community
Thanks for what you do... Wish I was your younger bro!!
Haha why is that?
Your videos are so cool, tnx✌👍
You are welcome
How does it recharge?
Great video, dont forget to give back that tooth brush you borrowed lol!
Yep she won't forget after this video...
my car battery requires distilled water. What kind of batt is it?
2.1,2.1,2.1,2.1, 2.1,2.1... HAD ME ROLLING😂😂😂!!!!!!!!!
Haha I didn't mean to say it like that...should have just remembered my timestables
Ha!!!Ha!!!Ha!!! I went back and kept repeating that part over and over!!!🔊AND IT GETS FUNNIER AND FUNNIER 😁🤣😂😂😂😂😲😂😂😂😂😂😱😂😂😂😂😂😂😂😂!!!!!!!!!!
I absolutely love your videos... great job!!! Keep them coming!!! You're so darn funny!!!!!!!!!
nice video, please go ahead
You should have mentioned the reverse reaction in the video for recharging the battery
Yes I missed that.
No toothbrushes were harmed in the making of this video.
Agreed. Except, well maybe, my wife's toothbrush ...lol
You married a nice gal who lets you use her brushes ~ adorable haha. Awesome video, and amazing how things like this are surprisingly interesting. Thanks for showing us!
Yup except she doesn't have to know I took her brush right 😏
@@speedkar99 well that certainly means she didnt say no haha! (also she must have known what she signed up for hohoho)
Keep the video coming:)
Thanks! Working on it...it's winter here
"My wife's toothbrush" famous last words
Drum roll...
Haha xd
I AM SUCH A DOOFUS I GOT A NEW BATTERY TODAY AND WHEN I WAS INSTALLING IT I ACCIDENTALLY TOUCHED THE POSITIVE TERMINAL WITH A WRENCH AND ANOTHER PIECE OF METAL AND THERE WAS A HUGE SPARK!!! DO I HAVE TO GET A NEW BATTERY NOW? IT WORKS FINE BUT IM WORRIED I MIGHT HAVE DAMAGED IT.
Awesome
Thanks
Won't the reaction end at a point. How does it continuously produce free electrons
The battery is being recharged which reverse the reaction
Nice 1 bro
Thanks bro
Nice
Thanks
I think that used baking Soda should go into your brother’s fridge! 😛😛😛
Haha I took it out of my own fridge actually
I'd like to see an AGM battery, please? Thank you.
It doesn't have liquid, and has glass mats which soak up all the acid.
Good idea...I'd like to see that too if I get my hands on one
What happens if you put baking soda inside of the battery would it die because of the neutralization ??
Yes
speedkar99 Thanks 😊
5:53 why isn't it 4h2o ?
Nice overview but the chemistry could use some work. The equations are not charge balanced.It is not clear which reactions occur during charging vs discharging. I think during discharging the free electrons should be produced on the negative terminal for the external circuit and positive ions should go into the electrolyte.
I agree the equations aren't balanced, but the idea behind the reaction was what I intended.
damn good!
It sure is
Great vid...but yeah, CO2 is actually pretty harmful in certain concentrations...
I thought this was my teachers (Mr. Kahn) demonstration for a minute
If I remember from breaking bad, plastics dont melt in acid! thats why that battery housing is made of plastic.
Interesting, batteries are gone expensive and smaller. They only have a 2 year warranty after that they need to be replaced. At least you outdoors, in the start of winter.
Yes the warranty has decreased significantly
wait what? whos toothbrush? recently married?
😏
heeey gloves...nice improvement eh? :D:D:D:D
woops yep safety is number one priority :D:D:D
I definitely had to get proper gloves for this one...
If you do this kinda work daily, you need proper equipment, otherwise your hands will look like a tree bark after a while
And sulphuric acid is very itchy on skin.
Yikes! I don't believe I would cut open a lead acid battery.
Why not?
Just use an angle grinder 🙄
@@speedkar99 The PPE OSHA requires to even top off a battery is soooo lengthy, my employer started replacing them all with maintenance free types. It goes a little something like rubber apron, rubber sleeves, rubber gloves, face shield AND a wash down station. I pretty much equate them with cracking open a nuclear reactor anymore. Have I been brain washed?
This guy can’t be serious. This is really not “How a Car Batterie Works”. Maybe it is his wife’s toothbrush?
Yes how a toothbrush works
If your wife uses that brush she'll definitely have gum disease!
Hehe
She was supervising this video in case anything exploded
So I'm sure she took note
I take apart old batteries with an old hatchet to get the lead to make shotgun shot and slugs. My local auto parts store hates me because I keep their acid vat full. Lol
Also, it is possible to build an immunity to the acid. I don’t use gloves anymore.
...I’ll probably die of some sort of cancer...
Ouch! Becareful
Any update on your health ?
Try a Lithium battery next time maybe? and accidentally short it haha
Thanks, I will if I get my hands on one.
Destruction plus chemistry plus mechanics plus victimizing family members belongings....what's not to love?
Yep that's my style
Easy going 😶
Can I have my battery back now?
Yea
My wife toothbrush 😂😂😂
They work by being a microverse 🙄
It is the same your brother's toothbrush right? oh OK nvm :-)
No this one is pink!
Wait, you're married now!?
I guess
my wifes toothbrush lol
I won't put that back...or should I?
@@speedkar99 buy her a new one
Hotttt
It sure is haha
Also playing with your wife's toobrush is dangerous !
Why so?
Dangerous to whose child?
2.4 v per cell, not 2.1. Max Voltage on a 6 cell is 14.4 v. Get your math right
Hmm that's a different cell you got there
@@speedkar99 no, it's not. Its EVERY car battery. Want proof? Every production car ever made that has a voltmeter is set at 14.4. if your gauge is high or low of that, you have a problem. Also, use any analog multimeter on any new, charged battery. You'll get 14.4. cheap digital multimeters are useless for anything precise, but a decent Digi multimeter will give you 14.4, too. Only way you pull less than 2.4 from a cell is either a) cell is discharged and needs top off charge. Or
b) the battery is toast. Sulfation, stratification, an impact that knocked some lead sulfate out of the grid, something. You can also gas your electrolyte solution off. Faulty charging can lead to excess hydrogen gassing off and changing the chemical composition of the electrolyte to a more neutral pH. But a battery that hasn't been fried will give you 14.4.
What happened to your brother's toothbrush?
I just use what's most accessible
Wife's toothbrush?!!??!?!??!?!?!!? >>>>>> link to this video is
being sent to your local divorce-court!!!!!!!!!!!
Whoops
@@speedkar99 ☺
i want to see ur wife reaction after u used her toothbrush and backing soda
RIP
@@speedkar99 thanks for video upload u keep saying my wife tooth brush lol she must be real mad lol
why you don't use your own materials or clothes hein ?
Because I can just steal someone else's and not be responsible for it
I LIKE CHEESE AND IT TASTE LIKE ME AS WELL AS CHEESE
Hey I like cheese too.
What about chocolate?
@@speedkar99 Yah chocolate tastes grate
You are wrong pure pb is negative and pbo2 is positive
Your Wife’s toothbrush and ur brothers trousers
Yep! Making use of what's available 😯
wife toothbrushe?
Yep
😂😂😂
All Joy

Thanks. I was considering a German car for more interesting complexity but I don't want to invest in a whole new set of tools!
Why you gotta disrespect your wife like that? Joke or not, you're subconsciously promoting misogyny. Just stick to your brother's toothbrush because "haha sibling hate"
And what about spousal love 😏haha
I have my whore toothbrush..is it ok
انا طيب القلب ونصوح شكرا سلام
