How a lead-acid battery works

[clark]

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

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.

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

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.

This is rapidly becoming my favourite YouTube 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 like this channel very much for the simple explanations, but this video was surprisingly specific but straightforward to follow. Very good stuff.

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.

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

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'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.

YouTube's last hope.

Literally the only videos I get excited to see uploaded to this site.

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

One of my favorite personalities on youtube.

"now with current technology" lol unintended puns, though....

[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!

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.

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.

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.

excellent way Bill presents his video classes. superb tutor.
