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
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.....
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.
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!

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?
A bit of both. C, D and 9V batteries are pretty much phased out by today's devices. C and D are too big and modern electronics are efficient enough to not require 9V any more. AA and AAA are the most common. The choice between the two mostly comes down to space constraints. You can approximately fit 3 AAA in the space of 2 AA. Smaller remotes like AC remotes will use AAA while bigger ones like TV remotes will use AA. If they need it to be rechargeable and even more compact, they'll go with LiPo.
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.
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! :)
A day with a new Colin's Lab video is a good day
I've learned more about electronics from Collin, than anyone else
I 2nd that!
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.
Collin's lab is what you do best Collin. Keep doing you as your best.
I've started to get into basic electronic projects and this is a huge help. Thanks for the video!
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
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
Finally!! Your Back! FOR SCIENCE!!!
Many thanks for essential information of battery, wish you and family the best , stay safe and healthy
I really like these videos. Collin's is great. So glad it is back.
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.....
when he threw that led with a magnet and battery at the ceiling had me dying haha I'm gonna do that.
"Classic."
Thanks! Please explain about Lifepo4 as well.
super nice, clear explanation of batteries we use everyday without really knowing what they are
Perfect video, thank you so much :D
Nice. Thank you for the video. Where do nickel cadmium batteries fit in a this. What are their characteristics?
I enjoy watching your videos , u have ur way of making science so enjoyable
Collin's Lab is the best!

dude more videos
There r young aspirants who can understand electronics really easily really nice dude
Collin is my new hero.

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

You, sir, got a new subscriber 👌🏼
Awesomely explained
Your videos are awesome.....keep going.. I love all of your videos.
Collin is my reason for life
Nice synth schematics in the background.
My favorite is the Ni-Cad after LiPOs.
Lead Acid Batteries are 12V and not 2V. I think it was a typo in 5:23
Amazing Video. Hats off to you sir... Impressive....
Love the videos full of good information.
More Colin!
Collin, maybe you should include some explanation on C-rating and discharge curve
do a video on the new solid state batteries
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?
Maybe you can create your own lesson in Hebrew for your students.
Thank you for sharing this video , really useful to me.
شكرا جزيلا على المعلومات القيمة
more we need more.
Please
Colin is the man!!!
Your videos is amazing !!!!!
Is the (-) terminal is actually 0v or nagative voltage?
How will you get the LED down?
very informative. thank you
I really wish to meet him once..!!
Excellent.
I'm impressed!
Finally your here again
Whats with pseudo random?
Hey at end you charge us and discharge your self ?
There's a RUclips channel called ' Grand illusions' and the presenter looks as if he could be your long lost great uncle
oh come on we need more videos

So why do lipos explode?
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.
yes yes and yes Collin
Stellar
yes 😀
lead acid has 2v? is that a typo?
Matthew Roh per cell, so a 12v car battery has 6 cells in it.
Collins lab is the best
What happened the Apple cell phone the battery expanded ,
when charge it hot and have to return to apple store the cell phone
Exelant
Aren't there recycling points for alcaline batteries?
Your local waste disposal place should have a collection point for alkaline batteries, look online at your landfill or recycling service.
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! :)
you'd need a protective charging module. you still need to be aware of the dangers though.
im thinking that i might just go with 3x AAA ;)
I've never seen someone make themselves yawn. Sure worked on me.
Best 😍 ever
TX, really...didn’t know so much existed
Testing battery condition with your tongue is the only reliable way of measuring both Ampere and Volt at the same time...
sweet.
I wish they still made mercury batteries.
I'm absolutely shocked that there was no mention of carbon cell batteries!!
3:46
I didn't know that
Da boss
i tasted a 9V battery too when i was a kid 😂
so in human body is it called glycogen and fat?
underdog
classic
i have a milk frother! i know what that is!
You are so much wrong. I don't know where to start correcting...
