## 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!

## 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)
