I remember as a child taking apart such a nine-volt battery. And instead of six small cells inside, it was all completely filled with some kind of black viscous and damp paste, and two contacts at the top were connected to two rods of something similar to graphite that were in this black paste.
I wonder if that wasn't a 6V lantern battery -- those had four 1.5V cells, much longer and a little fatter than a C cell, but connected in series like the AAAA cells inside a 9V. I used to use lantern batteries to power the igniters in model rockets. The cells inside the 6V battery were often carbon-zinc (cheaper than alkaline cells, and because they were large they didn't need the last little bit of efficiency), with a zinc can forming the negative terminal, and a carbon rod embedded in the damp paste electrolyte forming the positive terminal (the carbon rods could be removed and used to make a carbon arc torch or arc light). Of course, some really old 9V batteries might have had a stack of rectangular 1.5V carbon-zinc cells to make up the 9V, but as far as I know they've used round AAAA size cells (like in this video) for at least fifty years. And, of course, there were the huge (usually round) 1.5V cells with a terminal in the center and one at the edge that we used to use to power the glow plug to start a model airplane engine (the kind that ran on alcohol with nitromethane and oil mixed in) -- they were originally for powering the filaments in radio tubes (one, two, or four, depending what kind of tube, forming the A battery, with a smaller battery usually running 22.5, 45, or 90 volts for the plate B battery). Those would have had nothing inside but the electrolyte; the center positive terminal was directly mounted to the carbon rod, and the outside negative was on the zinc can.
I have an HP touchscreen Laptop with an active pen. It uses an AAAA battery, which can be hard to find and expensive. I use the cells from 9V batteries and they work ok.
It depends. There are constructions with 6 small batteries, and others with paste. I once saw one with a plastic container with layered masses. It looked nice, but I don't remember the brand
BTW You have to be careful with their disassembly. When I was a child, once such a small cell from a 9V battery exploded in my hands when I was disassembling the package. It ruptured at the positive terminal I think. Colleagues thought I had thrown a firecracker. I was fine, but I was in quite a shock
some of em use different cells and not actual AAAA's they have aclear plastic on it and you can actually see inside the battery and the 6 cells stacked!

You just answered one of my life's great Mysteries thank you
Now the question is what’s inside the smaller batteries
even smaller batteries 🤣🤣
nah just kidding there are lots of chemicals and electrolytes in there that of course make the battery up
@@Random_4400 small 12 volt batteries have smaller batteries inside
Its probably graphite acid lithium and other chemicals
more little batteries 😂
Like Russian nesting dolls, just more and more batteries.
Not what I found when I opened one up, same brand too :)
Those are AAAA batteries. If you have a tiny penlight that needs an AAAA battery, opening up a 9-volt is a great way to get one
i just open it to get AAAA battery but not all 9v battery inside have AAAA battery some got rectangle like granite
@@workout4life79 Yeah, some have flat cells
I have an HP touchscreen Laptop with an active pen. It uses an AAAA battery, which can be hard to find and expensive. I use the cells from 9V batteries and they work ok.
Whoever never placed the tip of their tongue between the two terminals never had a childhood 😅
They have changed the design again, now theres 6 clear plastic biscuits stacked up inside. Same brand same battery 2022
"We'll just take a pair of pliers"
*grabs a side cutter*
"dykes" for us mechanics out there
Who would have guessed that battery is made up of smaller batteries?
Technically cells
Now, what's inside the pliers?
Thanks for showing this. Duracell batteries have got to be the worst for leaking out and ruining things in my experience.
Thanks. Nice demo!
I need more AAA batteries I had a hunch and I was right thank you
Dude don't! They are not safe enough for that! Just buy new AAAs!
thank you so much :))))
Thank you!! :-)
Thank you
Great Info Thanks

Nice & Thanks :)
I'm confused on why you didn't do a heavy duty 9-volt battery to
That's so cool
How to you open it without breaking the shell?
I am thinking that batterys in 9v
are those AAAA batteries?
I believe so...
I see in the tiktok duracell battery has a small battery but this real ;-;
Bro risked his life for a video
It's a AAAA battery
mine looks differnt kinds weirdn
They are aaaa batteries
My whole life is a lie
Is it rechargeable?
Those are 4a batteries in series
1 x 9V = 6 x AAAA batteries
🙂👍🏻
HOW DARE YOU KILL 9-VOLT FROM WARIOWARE
