## Introduction: 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!

### Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: 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!

## 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 place...to 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)

Looks incredible :) I use this guide to recondition batteries at home. Very good way.

That is HILARIOUS! Just so happens wife stumbled upon your Instructable and came running in to me, GET YOUR STUFF.... Were going to Wallie World.... Thanks for the laugh.

Hahaha
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!

:D

WTF... not really funny. BE CAREFULL: you should NOT OPEN any battery yourself!

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

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

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.

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 cool.my instructable i posted on december and its not even 3 stars...be proud of what you have..make your own ideas...my instructable is on how to make a homemade headphones,its never been on before on instructable.

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

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

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

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