Introduction: 9 Volt Battery Hack!

About: Tinkerer, hackster and prankster. Hit me up on Facebook: https://www.facebook.com/kipkayvideos/ Thanks for checking out my Instructables!
Here is how to extract 6 AAAA batteries from one 9 volt ENERGIZER battery and use them like AAA batteries!



Step 1: What You Need...

1 ENERGIZER 9 Volt Battery.

ATTENTION: I do not know if this works with any other type of 9 volt battery. If you try this and end up with something other than what I show you, then you are not using an ENERGIZER battery.

2. A pair of needle nose pliers and a small screwdriver

3. Optional: Gloves

Step 2: How to Do It...

Along the edge of the ENERGIZER 9 volt battery is a crease where the case is joined together. It is basically just crimped together to form a seal. Using the needle nose pliers and if needed, a small screwdriver, carefully peel apart the ENERGIZER 9 volt battery. BE CAREFUL!

Step 3: What's Inside...

When it comes apart, you will find 6 "AAAA" or "quadruple A" batteries that each hold 1.5 volts, the same as a AAA battery. Remove the batteries and also the metal tabs that connected the batteries together.

Step 4: How to Use Them...

Since these hold the equivalent voltage as a standard AAA battery, they can be used in a device that holds AAA batteries. The only difference is that they are a bit smaller in length. That's why you need the connector tabs. You can fold the tabs over and use them as shims between either the positive or negative side of the new AAAA batteries and use them in any device! Have fun!

I recommend the cheap sunbeam batteries you can find at dollar tree and if you need it to be bigger you could hot glue or solder a sprong to the end

I opened Panasonic Alkaline 6LF22PA / 6LR6PA / 1BDR (Made in Malaysia and bought in Dollarama in Canada) battery and it didnot work it. It had flat batteries inside. My tip is open the battery from bottom, and dont open too much. Just open bottom 25% you will be able to see if it has flat batteries or AAAA battery.

I dismantled a 6LR61 Energizer 9v battery, expecting to get six LR61 batteries just like the video said. I was disappointed. I got six stacked rectangular cells (6F22?) instead. How is this so? Can anyone care to explain? I'm starting to question the authenticity of the product. Sheesh! I felt so ripped.

Maybe battery tech has moved on in the 8n years since this article was written?

I tried energiser alkaline 12-2019 (black and silver), Panasonic NEO extra long life (black and silver), and Panasonic Hi-TOP long life (red and white) and they all had the flat cells, no AAAA's

Here's a tip, If the battery is a HEAVY DUTY or SUPER HEAVY DUTY battery, there will be a thick, toxic (if ingested) gooey paste, if it is a ALKALINE battery, there will be six AAAA battery cells inside.

Ha cool i thought you could only lick 9 volt batteries

It works on certain kinds of batteries and not others. They probably just tested the wrong battery. It has worked for me.

I just did it today and for everyone who thinks this is a hoax look at what I got

Uh... I ripped of the label saying what brand it was.
But it was kind of like button cells stacked on top of each other.
It's just that these 'cells' were see-through and had paste inside.

This is an excellent hack when you need to replace AAA batteries, but when you need AAAA batteries,there are more differences between these cells and store bought AAAA cells; 1) The polarity is reversed so that the negative terminal is the one with the little "Button" on it, 2) that little button doesn't protrude as much as on a store bought cell, and 3) the hacked cells are just a tiny bit shorter than their expesnsive counterparts. My Streamlight Stylus LED flashlight won't work with these cells. I think that it requires the positive terminal to protrude into the LED assembly. I tried to remove the "button" from and old AAAA battery so that I could use it to extend the flat positive end, but I was unsuccessful. Does anybody have any suggestions that would make these AAAA batteries more functional? Thanks, Matt
