Introduction: 12 Volt Battery Hack! You Won't Believe Your Eyes!!!!! (updated)

Picture of 12 Volt Battery Hack! You Won't Believe Your Eyes!!!!! (updated)

Inspired by the instructable by Kipkay I thought I'd pick up some of my own batteries of a different brand...And, boy, was I surprised!

Step 1: Open Sesame:

Picture of Open Sesame:

I bought the batteries in a two pack at "ye 'ol supercenter" for about $1.88 US. After unpacking them, I just used my handy dandy mini leatherman to pry up the casing on the positive end.

Step 2: Pry It Open

Using the leatherman, I worked my way down to the negative end of the battery.
Note: Be careful, the outer casing of the battery is sharp!

Step 3: OMG!

Is that what I think it is!?
Imagine my surprise when I saw what was inside and dumped it out...

Step 4: Still Amazed

I was astonished! A rolled up $5 bill and a 1.5v button battery!
You have got to be kidding me!
If I knew about this sooner, I would be a rich man.

Step 5: Whew

I had no idea a $5 bill would conduct electricity, let alone up the voltage an additional 10.5v. I wonder if different denominations have a different effect...

You'd think battery companies could come up with a more economical way of making a 12v battery. Especially since the things only retail for under $2.
Their loss, our gain. Am I right?

Well, thats it for my very first instructable.

Hope you all enjoyed it!

It was at least worth a laugh I hope.

Kipkay, thanks again for making the instructable you did. I'll definitely be using what I learned from yours to help me with some electronics projects. (I'm always in the market for another source of cheap power)

(BTW: if you haven't figured it out i was just joking. don't go blowing your last two dollars thinking you are gonna come away with another ten.)

Step 6: Okay Okay

Alright, what you really get is 8 button cell batteries per 12v battery.

So this instructable isn't a _complete_ bust, I'll add some steps to show why I wanted the batteries in the first make a small 9v using six of the buttons.

Step 7: Ta-da!

Here's what you wind up with. I'll insert the steps before this weekend is over (my camera battery needs charging first)

Dude, you should be mor careful with this stuff. Most people will do what you said and won't care to read the whole instructable. Well if they buy the sutff and tear it apart, call Duracell and claim some money for the advertising!

geeklord (author)synox2009-01-03

YEA!, and guess what, I'm still alive andfully functioning.

ReCreate (author)geeklord2009-07-25

WOW WOW WOW WOW ORLY ORLY?(if you don't eat it daily, you should stay alive XD)

whatup.dub (author)synox2007-08-31

The real battery had 8 button "watch batteries" in it in a wrapper. (already knew what I was going to find) But I agree, opening batteries is dangerous.

joinaqd (author)whatup.dub2009-01-15

dude you have plagerized other people work therefore i have given you a 0.5 star.dont you hav somthing else to make?like seriously dude stop copying,its not instructable i posted on december and its not even 3 proud of what you have..make your own instructable is on how to make a homemade headphones,its never been on before on instructable.

Project D (author)joinaqd2009-03-24

Yeah, but...his is funny. Yours is kinda boring. He gets my vote.

Redgerr (author)synox2008-07-20

once we see that it is safe (from kipkay) then it is okay because you can't hurt yourself with the 12v. I do understand hat it is dangerous to open any other though

mspark400 (author)Redgerr2008-11-21

Except for most 9 volt batteries as they contain 6 AAAA batteries. Be careful though as some 9 volts still contain a non sealed battery. cheers, mspark400

Yes, Very Strong language...

lemonie (author)ReCreate2009-07-23

Wow that's really old, and still there. I might remove it (language)


ReCreate (author)lemonie2009-07-24

Ha, Well you did remove it now.

lemonie (author)ReCreate2009-07-24

I still found it amusing, but less than I must have done onriginally. No value in leaving it there really. L (thanks for reminding me of it)

ReCreate (author)lemonie2009-07-24

Now what is my reward?

lemonie (author)ReCreate2009-07-24

Name a patch you'd like and it's yours - I think you probably deserve one generally. (and if you point me to the image you want you'll get that) L

ReCreate (author)lemonie2009-07-24

Hmmm...Its so hard i don't know what...Maybe a cookie?

RidoKilos (author)2008-02-04

I have to admit I was a little tripped out by that for a second.

Redgerr (author)RidoKilos2008-07-20

lol, i thought it was a stealing plan by the company for a second too ;)

mcpguru (author)2008-04-09

Watch out when you split the battery open, I had one of the internal parts jump for it. For the record, I just wasted about 10 minutes trying to figure out what the LR 932 battery might be by another name, and haven't found much yet.

KeviBear (author)2008-04-05

Does every Type of battery have the little battery's inside of them?

Derin (author)2008-04-05

nooo! mine has that trash -n- cross -n- Hg sign!
