In a laboratory at Oxford University sits the Oxford Electric Bell, which has spent 176 years constantly ringing. And no-one's quite sure what the battery that powers it is made of...

just cut it open so we can have Tesla that lasts 176 years without charging

I already knew it, I am proud of myself

Although the battery is really impressive. Making a bell ring for 178 years is about the best way to drive your friends mad, for generations to come.


Tom Lynn 

is the actual noise it makes included anywhere?


Christopher Dibbs 

"Kara"


Chris Glass 

Baghdad Battery is older ;)


virustwin 

now, how do i get tit in my phone


Phoenix Grimm 

Cough. There are lightbulbs stil burning after 100 years but the makers of lightbulbs figured they wouldn't make a profit that way so now they make them burn out and waste resources.

They open it to find a duracell


TRU MAN 

Isnt this technically a perpetual motion machine?

I can't even get a AA battery to last a week.


Cranky 

shut up so i can hear it !!!!!!


Jacob Gamesbillion 

Energizer would like to know your location


Cida Faria Juliano 

Amazing! Astonishing!


Banter Shrimp 

God I wish my iPad had that battery life boi.


score fresh 

why aren't we powering the uk power grid with it?🌕


Panther Platform 

Looks like someone bludgeoned that chick in the side of the head...


Driftveilldraws 

apple should visit this place and learn how to make longer batteries


Angel The Mage 

maybe once it (at some point) stops, we can dissect it and discover what it was made of. then we will have never ending laptop life (not that i have a laptop)


Daniel Pierce 

Let’s be real tho, the Egyptians invented the battery, or at least that’s the oldest evidence of a human made battery existing we know of...


EVILBUNNY28 

Um. Stick it in my phone now please?


Mnr.StelJouTabel 

What do they mean almost continuously what happened


Last Time 

Wow


GOD OVER MONEY 

Al-You-Mihn-Ee-Um

OMG these British are something else !!!


GOD OVER MONEY 

Funny how the British always add an extra syllable to the word aluminum


Cael Pley 

holy cow 176 YEARS HOW??!?!??!


Zdravko Vila 

My gameboy lasted 1 year


Alex 

She's awesome


usernamedkjah 

There's a bit of a god in it... For science and the tiny gods are one in the same


Just Kidding 

Duracell hasn’t got *anything* on these those!


Ryan Park 

How do we know that no one has secretly replaced the batteries with new ones?


Sketchy Tiger 

Phone battery makers need to take note of this battery 😂


ddoogg88 tdog 

Where can I get one for my phone


Raul Alarcon 

Only if my iPhone’s battery lasted this long....


William Bogue 

So was it made in 1825 or 1840?


getLocation 

WTF Samsung / Apple? You can't even keep your batteries reliable for more than 1 year. I want this thing in my phone 🤨


Michal W 

"Baghdad battery" 6k y. b. c. Chinesse electric wase 1k y. b. c.


Scott Helms 

Just imagine having to maintain a warranty maintenance network for nine generations.


Tha Hoova 

batteries where made wayyy before this by the ancient egyptians


— ꧁꧂ — 

Why don’t we have this stuff in our phone?


hitter kitten 

i need one for my kindle fire!


Ison Reign 

Why dont we make a giant one?


Rup Ganguly 

Why the hell every host of this channel wear's red


corgidog 

Could you not xray it?


Adagio Leopard 

By the title I thought it stopped ringing...


Ethan3369 

So I think I got some math wrong 10 nano amps and 2kv is 20micro watts and if has done that 10 billion times and it only say 10ms a bell strike then that's is 100 million seconds at 20 micro watts or 2kwh of power


DeDraconis 

Wow the salt from people who want to crack it open in this comments section is real. Relax. The key to your cell phone lasting longer is not in there. If that's all you want, just disable updates around when a new version is being released.


Lee Fire 

Before you leave, can you check to see if the flat-earthers are right, or at least check for a giant hole that leads to the inner earth? I want to watch some conspiracy theorists cry.


I react to everything Everything 

178 years*

I think it is ignorant not to take it apart and learn what was done right. The possibility of discovering the why about this battery far outweigh the nostalgia of wanting to see how many more years it will run. Considering where we are today with battery technology and the critical importance they play in todays world you would think that science would be more interested to know the answers in the hope they can apply similar methods to improve what we clearly have failed to grasp about this technology. For me what I find amazing, more than the length of time this battery has been working is the utter ignorance of so called educated people who find it more important to want to know how long it will last and seem oblivious to the idea it may hold the proverbial key to what we have been doing wrong since the invention of this technology!
