How a lead-acid battery works 

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

Making use of the ru-vid.comUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 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

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!

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.

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.

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!

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

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

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.

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.

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

This is rapidly becoming my favourite RU-vid 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.

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!!

One of my favorite personalities on youtube.

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!

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

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.

This man has taught me so much, and made me even more interested in things that I know about

excellent way Bill presents his video classes. superb tutor.

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

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!

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!

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.

Bring back Engineer Guy! I need more!

Excellent video. Extremely informative, and very well presented. A well deserved thumbs up from me! :)

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.

Thank you very much for this video.

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!

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

I love this guy. Explain easy and clear all about the technology. Very, very interesting.

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

excellent production, greatly informative. I completely agree regarding "natures gift" to us. Simple, clear, well done.

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

Your explanations are perfect . Thank You .

Please I really miss your videos and y would enjoy more of them. Thanks for your efforts . I know you are working on it but Zhou have a lot of supporters encouraging you here!

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

Very informative information, Thank you for explaining this in a manner I can understand.

Beautiful and amazing video Bill like always.

Excellent explanation.

Very helpful, concise and precise, thank you Sir

This channel is an inspiration to me.

Respected Sir, thanks for such awesome videos giving informations. this is really an eye opener for us. you are really blessed.

this the best channel on youtube. period.

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

Good video with real lead acid battery. Thanks.

one of the best channel on youtube....by quite a long shot.....

You have a great video here, You're very professional and the video is well edited so that it is all around a very well made teaching video.

Awesome video as always Bill! Cant wait to see your next series of vids! :)

Found your channel while watching Veritasium. Subscribed. Excellent stuff.

You are a brilliant teacher.

Thank you for making such interesting videos.

Thanks for showing me once and for all what is inside my car battery. :-)

Thank you for the great explanation!

I love this guy show, Excellent explaining everything. Thnkss

you've got to love this guys voice! :)

I can't believe there are 3 people dislike this great video. Keep up the good work.

Such an underrated channel.

Excellent video!

thank you for all the wonderful knowledge. Every time after watching your videos (and i've seen all of them) I feel like curing cancer or creating renewable energy, or some magnificent feat through the intricate designs only achieved by engineers.

As always, a wonderful video. Saw that the book is now on iBooks, so I bought it!

Thank you, engineer guy, your videos are very amusing, informative and useful. Hello from cold Russia.

No idea what any of this means, but just hearing you explain scientific stuff and display all these cool things intruiges me enough. 👍

Thanks for another knowledge bomb! Great video!

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

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

Thanks a lot for making this!

Eloquent and precise.

I was wondering how batteries work. Thanks! :D

Excellent content. Bravo!

I could watch these videos all day

Engineerguy pointing at lead acid battery while shoving away the lithium ion one: " This might be the most important one of them all" Lithium ion : "Hold my battery water.."

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

Excellent video. Have there been any recent developments in graphite gel capacitors? I heard some years ago they are a potential replacement for conventional batteries as we know them.

Looking forward to your upcoming videos, i saw the ones you are working on atm looks interesting.

This video is 8 years old, but still useful today

I think it's a prefect explanation!👍

Excellent video. I'm reading the Atomic Clock chapter on my Kindle version of your book. Very Interesting.

Finally I know how battery works. Thanks!

Listening to you, I feel I know everything. Thank you...

great explanation

Very well done.

ok sounds good cant wait! keep up the good (hard) work guys i can only imagine what kind of time and effort you put into your videos =)!

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.

bill, when ya comin' back?

you look just like the main character...love your videos btw! hope to see more soon!

You were always my saver...now too...since the starting of my class 12!

Great book.

you're awesome and I love your voice!

excellent video ! Thanks

Best channel on RU-vid.

Great video. Thanks!

Thank you for this.

thanks for this great video

engineerguy blows my mind. He's the kind of person who whilst growing up just wanted to know how everything worked. So he found out.

Woohoo! new video, i always look forward to them.

That makes me sad, but I understand. Please continue to make awesome videos!

I love how your videos are in creative commons

That sounds really great. I hope it all becomes possible for you soon. :)

Please answer my question : At the cathode end there is always electrons leaving battery continuously or it started after we connect wire? ☺🙋

Wow!! Very educational! Thanks!
