How a lead-acid battery works

Bill explains the essential principles of a lead-acid battery. He shows the inside of motorcycle lead-acid battery, removes the lead and lead-oxide plates and shows how they generate a 2 volt potential difference when placed in sulfuric acid. He explains how the build up of lead sulfate between the plates will make the battery unusable if it discharged completely, which leads him to a description of how to make a deep cycle battery used for collecting solar energy.

It's been more then 8 years yet this is still the best summary on how a battery works.

[@jacquelinecook5613]

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

[@kiq4767]

beware scam

[@LMacNeill]

Lead acid batteries are still practical, not only because of their unique properties that aren't matched by any other battery type, but also because we have an amazing lead-recycling infrastructure in place -- and we've had that in place for decades now! Lead acid batteries are *the* most recycled item -- more than 99% of all lead-acid batteries used today are recycled! (Compare that to 50% of aluminum cans, and 70% of office paper!) In fact, it's very likely that the lead in your car battery today was mined 50 or more years ago! It's been recycled that many times!

[@tubester4567]

what about the acid though.

[@kingofthespazs]

its a simple process to create and so long as we pay attention to recycling easy to reuse or enrich the acid

[@Admiral8Q]

Glass is 100% recyclable. Though the problem is some people like to smash it all over the place.

Capacitor banks are way better than car batteries... look em up

[@BlackJavaBean]

I really enjoyed the explanation of trade-offs. As an engineer, I find that is the hardest thing to explain to the users; no matter what the design, there will always be some kind of trade off.

[@somebeinganonymous]

Really enjoyed this one, especially the conversion of the sli to deep cycle illustration.

[@ErnestJay88]

This video is 8 years old, but still useful today

[@nosx858]

im thinking of transferring out of my university because im an electrical engineer but all my physics and chem teachers are horrible most of the stuff i have to learn on my own and spend hours researching it because they cant explain it, you make me feel like transferring to the University of Illinois because your sooo goodd at explaining complex concepts! i love your videos

[@balls2balls]

Bill, I just wanted to say this was my favorite topic in the companion book and I enjoyed the video very much. The visuals in this video helped me understand the concepts even better. Thank you!

[@randybuttigieg6776]

Great job on these videos! Your explanations are clear and concise and you don't dumb things down, I'm thoroughly impressed and I want to thank you for taking your time to do this.

[@Nova5005able]

KZbin's last hope. Literally the only videos I get excited to see uploaded to this site.

[@drprincehealthfocus3249]

i usually don't subscribe to any channel but after watching, i had to. your explanation was so detailed yet simple enough to understand and you have good practical examples.

[@sirNemanjapro]

Just to let you know, that your videos are being watched all the way in Trnava, Čačak, Serbia. :)

[@artyshmunzuk5435]

Mark Hamill is so multi-talented

[@PGHolmes]

One of my favorite personalities on youtube.

[@Richard-ig2gv]

Great quality content. Straight to the point. Short, concise, knowledge-packed video.

[@orcasha]

Watching the videos and reading the book gives me no end of appreciation for engineers. Thanks for everything.

[@ScibyTravels]

This is rapidly becoming my favourite KZbin channel. Bill, have you thought about doing some videos explaining more simpler concepts of engineering (eg: electrical concepts, ohms, amps, current; or the laws of thermodynamics, etc etc) Your presenting style would really lend itself well to it, imho. Definitely better than my high school chem/physics teacher. :) anyway.

[@controlledburst]

This may be the best explanation I've seen. Even answered a question that arose in my head regarding "off-the-grid" power storage app.Thanks!

[@spelunkerd]

I'm glad to read that you are busy making more videos. One point also worth considering when discussing lead acid batteries is that the acid freezing point is much higher when the battery is discharged. So, if you store equipment outside in winter, the battery should not be allowed to discharge completely, for two reasons. First, sulphation may shorten the life of the battery, and second, the discharged battery may freeze and crack, mechanically killing it much more quickly.

[@roeltz]

I like this channel very much for the simple explanations, but this video was surprisingly specific but straightforward to follow. Very good stuff.

[@roeltz]

Now I realize this video is two years old and I feel ashamed.

[@engineerguyvideo]

Leonardo Rothe Tagliafico Thank you for your kind words ... much appreciated ....

[@diggerpete9334]

Engineer Guy is such a great teacher of what's behind common everyday things and so clear to follow. Subscribed with pleasure.

[@tehguitarque]

I as well love and appreciate this channel. I was expecting a part about recharging the battery though. Is the reaction reversible up to a point?

[@ytanonymity3585]

I would love to learn how to developed a battery especially on how to create a Laptop battery and make it last longer

[@hobojakobo]

Bring back Engineer Guy! I need more!

[@zeddjb]

I really liked this video. I never really knew how those batteries worked. I always learn something new with your videos. Kudos to you and your entire team!! Great Job Everyone!!

[@nickgates6829]

Good on ya mate, well done. The perfect balance of complexity and time. Would love to see scope and sequence across other battery systems like LiPo for my students - and myself! Keep up the great work, and the books too!

[@ID10Tpig]

Such an underrated channel.

[@howardsix9708]

excellent way Bill presents his video classes. superb tutor.

[@Vehshya]

I could watch these videos all day

[@BonezTwisted]

Very educational video. I change lead motive power batteries at work and always wanted to see the inside of one. Soon I will be a battery technician repairing or replacing busted cells.

[@philbot01]

Do a kickstarter. Make videos and put it in the description. People love this stuff!

[@Uselessfish1989]

Just watched all of your videos in a sitting. I love them. Keep up the great work. I'm definitely going to get your book soon. Thank you for these, you're awesome!

[@rejinyahel2170]

me too after 9 yrs

[@GeckoMoria94]

A tip for future videos. Don't shrug your shoulder so often. Once you notice it, it's hard to ignore it. Love your videos.

[@VBlogMag]

Brilliant video..I'm busy testing how well lead crystal batteries do at very deep cycling. Cheers, Martin.

[@DarkSayno]

I love your work, Bill. I would love it if you dedicated a few episodes to a few mechanical processes that makes cars work. Like the internal combustion engine, or the differential or anything related.

[@EdwSch]

Thanks for the update. Really looking foward to what you have next!

[@longquan5790]

We love your videos bill, hope to see more!!

[@xodus59]

When are you coming out with more videos?! I've learned so much from them and I can't wait for more!

[@StuartAlldritt]

I really enjoyed reading your book, but please please please release the next season sooner this time! I love these videos and can't wait for more!

I've had good luck desulfating batteries by temporarily using high current from an already charged battery to bring it up to a chargeable state.

[@mr.dr.k3148]

Connect a larger battery in parallel, with a charger simultaneously connected, until the charger registers the otherwise, inert battery?

Please keep going beyond theory as you do in this video. Thanks for sharing your knowledge.

[@Laogeodritt]

In solution, sulphuric acid forms the equilibrium H2SO4(aq) ↔ HSO4-(aq) + H+(aq). The presence of the proton (H+ ion) is what makes a solution acidic. The acid's conjugate anion (HSO4-) is what was shown reacting in the equations.
