A day with a new Colin's Lab video is a good day

I've learned more about electronics from Collin, than anyone else

He has a way of really breaking it down while making me feel groovy at the same time. Thanks, Collin! Nobody helps me learn more about electronics projects and electrical engineering pertinent theory than you do!

This was my first "Collin's Lab" video. Great delivery of the topic.

Dude, you have the best dry humor I've run into in a while. Great info as well and very well explained.

when he threw that led with a magnet and battery at the ceiling had me dying haha I'm gonna do that.

Collin, your videos are really great and I have enjoyed watching them and learning over the years. I just wanted to say Thank You. Bill

Collin's lab is what you do best Collin. Keep doing you as your best.

I just cant get enough of these videos. tremendously informative and this was one of the funniest ones ive seen to date.. Please do keep producing these videos.. you need to get your own show, seriously.. thanks from Vancouver, BC

I've started to get into basic electronic projects and this is a huge help. Thanks for the video!

I really like these videos. Collin's is great. So glad it is back.

Many thanks for essential information of battery, wish you and family the best , stay safe and healthy

I enjoy watching your videos , u have ur way of making science so enjoyable

Excellent way of educating a hard subject, Collin your entertaining presentations are tempting to follow endlessly. Thank you very much for your knowledge sharing....God Bless You.....

super nice, clear explanation of batteries we use everyday without really knowing what they are Perfect video, thank you so much :D

Thank you for sharing this video , really useful to me. شكرا جزيلا على المعلومات القيمة

Finally!! Your Back! FOR SCIENCE!!!

Your videos are awesome.....keep going.. I love all of your videos.

Happy new year to all at Adafruit and Colin Cunningham. ;-)

Love the videos full of good information.

Awesomely explained

It helped me A Lot to learn the reasoning in the number code on most CR-coin cell batteries. I live in the metric part of the world so it's kind of easy. So the numbers correspond to the dimensions. For example [ CR1025 ] = 10mm diameter x 2,5mm thickness... or CR3032 is 30 x 3,2 mm etc... I don't know why they aren't more consistent but it helps to know approximately what you are looking for.

Collin's Lab is the best!

5:52 starter lighter ignition (SLI) lead acid are good for huge currents for starter motors, not to discharge and charge, deep cycle lead acid are good for charging dscharging for backup power

Amazing Video. Hats off to you sir... Impressive....

very informative. thank you

Thanks! Please explain about Lifepo4 as well.

Your videos is amazing !!!!!

Collin is my new hero.

You, sir, got a new subscriber 👌🏼

My favorite is the Ni-Cad after LiPOs.

Colin is the man!!!

Can you make a third battery video that explains how alkaline recharging units work now? I'd love to see some of the chemistry specifics. I have a recharging unit that has a sliding switch to change between nickel metal hydride, alkaline, and one other type. It works decently for alkalines but I haven't been able to find a good explanation for my chem students about why alkaline recharging is suddenly possible or what happens in the cell when it's being recharged and your explanations are so nice, crisp, and clear! Thank you for Colin's lab, I use them all the time with my robotics and physics class! Now I will use these battery ones with my chemistry kids when we do electrochemical cells!

I'm impressed!

Excellent.

Nice. Thank you for the video. Where do nickel cadmium batteries fit in a this. What are their characteristics?

More Colin!

Collin is my reason for life

Nice synth schematics in the background.

more we need more. Please

dude more videos There r young aspirants who can understand electronics really easily really nice dude

Stellar

I'll like Colin's videos a lot, and I want to contribute Hebrew subtitles for my students. Can you open the option to add subtitles?

yes 😀

I really wish to meet him once..!!

Exelant

yes yes and yes Collin

Is the (-) terminal is actually 0v or nagative voltage?

How will you get the LED down?

Collin, maybe you should include some explanation on C-rating and discharge curve

do a video on the new solid state batteries

Lead Acid Batteries are 12V and not 2V. I think it was a typo in 5:23

sweet.

Collins lab is the best

oh come on we need more videos

Finally your here again

What happened the Apple cell phone the battery expanded , when charge it hot and have to return to apple store the cell phone

Nominal cell voltage is just the rough average voltage to expect over the course of a discharge. A LiPo, while nominal 3.6-3.7 V, goes from about 4.2 when full down to 3.6 when empty. (open circuit) Alkaline go form 1.6v down to ~1 V. lead-batteries: high surge currents? for their capacity kinda yes, for their size/weight no. They are used cause they are cheap and don't degrade with lifetime as much and fail more gradually.

Whats with pseudo random?

Best 😍 ever

There's a KZfaq channel called ' Grand illusions' and the presenter looks as if he could be your long lost great uncle

Hey at end you charge us and discharge your self ?

So why do lipos explode?

Testing battery condition with your tongue is the only reliable way of measuring both Ampere and Volt at the same time...

I've never seen someone make themselves yawn. Sure worked on me.

TX, really...didn’t know so much existed

Late, very late, question from the peanut gallery, but I've always wondered - why would a manufacturer choose AAA over AA, or D, or others? For a while, I thought maybe it was just "which is the smallest I can get away with?", but after this video, I'm thinking, maybe, it's all about the mAh. Am I getting warmer, or am I (still) way out in left field?

3:46 I didn't know that

I wish they still made mercury batteries.

Da boss

Aren't there recycling points for alcaline batteries?

i tasted a 9V battery too when i was a kid 😂

lead acid has 2v? is that a typo?

classic

I'm absolutely shocked that there was no mention of carbon cell batteries!!

underdog

i'm doing a project where i'm making a larp nerf gun for the upcoming danish event sunfall, and i'm planning to put led's in the barrel. i really wanna run them of a li-po battery but i'm really scared im gonna puncture it because im gonna be combat rolling and dropping it all over the place... is it a horrible idea? also can i just say, that colin is looking goooood! that graying in his beard and hair really suits him! :)

so in human body is it called glycogen and fat?

i have a milk frother! i know what that is!

My pkcells!

You are so much wrong. I don't know where to start correcting...
