How to Make a Coin Battery 

what do you mean by undercharged metal? the aluminum? do you think one could use other metals like lead to still make a battery like this?

@@veganchocolatemousse basically if you look in the periodic table of elements,youll see metals in different groups. Metals like to lose their valence electrons which is their outermost electrons to form cations. And generally metals at the bottom of a group lose their electrons more easily. Also as you go from group to group the metals lose their electrons less easily. Which is why group one metals react explosively with pretty much anything. Sodium and potassium literally explode in water. Go figure. For example when silver and zinc are used. Silver is in group 11 and zinc is in group 12. Silver is more likely to lose an electron than zinc. And thats exactly what happens.

Of course it makes sense. You just described the basic principles of a battery lol.

What what what?

@@DIOBrando-ur5we i learned more from your 2 comments than from years of school 😂

+Norina F lol in this case it would appear so!

Which makes it expensive

+Norina F Literally yes :D

Can aluminum foil be used as a replacement for zinc in this battery?

If they are single cells, they are not batteries. Batteries are more than one cell stacked together.

+Furno Lt lol!

+DaveHax pretty cool indeed 0_0

+Furno Lt crazy russien hacker ;)

Thats so him!!

+Furno Lt THATS NOTDAVE HACKS HIS NAME WOULD BE HIGHLIGHTED

Lmao

JJT23 Why Do Battery Manufacturers Hate Davehax

@@dedchannel952 he show people how to make the battery so people can make their own battery its mean they can have free battery without buying battery from battery manufacture

Does it work forever

Bitch

Tesla didn't make the battery it was Alessandro volta

Alessandro Volta would like to know your location

That one B emoji what

i have the same question

Yes you would

Until the metal becomes corroded.

Good question

@ilikeminecraft6753 gaming inefficient really but I suppose.

+m2hmghb it's not like you're going to use collectible coins in a battery, are you?

Kids are known to do things like that all the time.

m2hmghb then why do you keep them in a place they can reach like no problem?

Geez nice way to make assumptions. I don't have kids, but I know of people who have had their kids spend their silver quarters and dimes when they did keep them in a safe place. It's a notice for parents to be careful if they have collectible coins in the house and decide to do this.

+m2hmghb What about using a sonic jewelry cleaner on them - would that affect their numismatic value? ~♥~

+Don Smith Cool thanks! Are you going to try and make it?

nice dave u are amazing i think youed make a brill science teacher if u ask me

+Mr. Random - Thanks very much!

+DaveHax I've subed to u would u like a shout out and I love your channel

ya, it's so cool!

employees battery company obv

+Hannah Louise Rose Thanks very much, I'm glad you like my stuff :)

+DaveHax Nice video! But can you tell us how long it will last? How much power it has...

+YourTrulyFriend depends..

+DaveHax can it power a xbox 360 remote

Bolloon Boy maybe two

Cool

Cool

For $$$?

I would just sell the copper.

@@collettemaurice7970 did you just say "cool" twice then question it?

Yh I see the stack of pancakes too.

Lol i saw that the first time i saw it

+Lord4of4Games same

I saw cookie....wtf

I saw macaroons

+MsMs_SS Thanks for the kind words...

+weirdstuffanimation7 not very long. until the vinegar dryed

+The Alpha Falcon so just soak it in vinegar

a couple of weeks so try it

wierdstuff

Only as long as there's still vinegar soaked into the card.

55 stacks of these and your good to go. 😂😂😂

@@Kopie0830 dont forget the 55 gallons of vinegar too

+Don Smith Thanks very much!

@@DaveHax how do you recharge the battery..?

@@TheRatLiker he does add it to the vinegar again so it will be rechaged

@@DaveHax i love you

@@DaveHax love you!!

+Felipe Yudi Glad you like it!

+DaveHax what if you did more than 9 can you do more than 4 volts? and how long does this power last after the vinegar is gone from the cardboard pieces of paper?

+DaveHax it is a hamburger ,_, can i eat the hamburger

can i do this with lemon without vinegar

yes, watch my video on my handheld flashlight that runs on lemon juice

Haha

@Venom yes i remember but if he try to save a quick buck that again you right

He could just do 3x3.

your the first ive seen to know about volta , bravo

Probably 5 seconds

until the coins and the aluminum foil finish reacting completely

This is actually How Batteries work 😂 just copper and zinc

I dont know but its too in my

its called youtube

No clue

@@chaoticflame2922 Hello fellow member

@@seemiihalainen7603 TIME TO SIMP WITH MIKE

2 minutes

@@jqproductions301 any way to recharge?

C maybe dip it back in the liquid he used

Tried recharging and it almost looks as if its feeding off the copper as it started reacting.

Yeah

+Nakeuru lol it's a conspiracy! :D

Go and change australian dollars to pences :) or euro-cents :D

Nakeuru I'm from WA in Perth

P.S. It's rechargeable

Christopher Craig-Huerta wow no way how do you recharge it?

i have 20 pennies

@@antonygonzalez1672 to put it simply, the copper is from the pennies is used up and the aluminum is eaten in the process. to "recharge", maybe switch out aluminum if there is any left and switch out the pennies occasionally.

Legendary Music of All Times 2.0 the aluminum won’t last long

+Gffgh Whoah that's a nice school you went to! :)

+Vinay Seth Yeah,my school is very nice,and I love it😁💓

Is grade 6 primary 6 in Britain

+thecarmaster45 Gaming no we call it year 6 and we call kindergarten foundation. :)

Um..

Adis - Ad LOL

This is pretty cool, huh?

Remus Lupin yup

yes it's very nice

Lol smart idea

+daduncker2.0 More like free emergency car starter, for when your battery dies and there is no other car to jump start yours

+daduncker2.0 Not enough current!

+daduncker2.0 Although it produces quite a high voltage, unfortunately it's not high amperage, so it doesn't have much power, it's ok for very small current draws though like an LED or a remote control.

+daduncker2.0 ,The 12v battery in your car does not "power the car",it simply powers the starter to turn over the engine.The alternator takes over from there.

Would the size of the coin determine the amperage?

Aha lol

I'm pretty sure they show this off in elementary school.

@@PilaCiu it's still pretty cool...

Nope

Nope

ikr!! thats what i though just to have a perfect row and column

Ok ok ok 1 I LOVE my smetricality and 2 maybe 'YOUR LIYING YOUR LIYING!'

Fake

@@theveryfunnymyth huh

Lol he is like me he will lose one tear one up and someone will steal the other that's why there are extras

If you want to be a tinkerer, this is the minimal gear required!

+The Cantonese Guy i did tht my freind asked why i said i was to lazy to go buy batteries he said "but you will make your own fucking batteries" me "pretty much"

+Detryk Willis Hahaha. I guess I would be that kind of person too. xD lol

nah the vinegar will dry out eventually or corrode the metal enough to make it not conductive. vinegar is chemically known as acetic acid, it still is one of the weakest acids, but it still can corrode things over a long period of time.

infinite power generation is not possible. eventually the copper will corrode or be depleted and the batter will not produce as much voltage as it used to.

I'm curious the economy of power production versus electricity production methods. Like if someone wants to scrap enough and aluminum essentially getting the items for low to no-cost, could One supplement their power consumption with these on-site devices?

I am also an educator and I plan on using this in class next week. I will measure as soon as I build and I will totally let you know! This is an awesome experiment!

Make a joule theif circuit

yeah that's what I thought too.

hey can u plzz tell me if i can use aluminium instead of aluminium foil

Stylish Kuri you can scratch off the bottom with sand paper that works too

but the coin here are only of copper both inside and outside too in pakistan

but i have made it with copper coin and another aluminium coin 😊 and got 10 volts

*claps slowly*

haha good one😂😂

... And the penny drops.

Yes plus foil and cardboards
