Did you know that the common Alkaline 9 Volt battery is made up of six 1.5 Volt cells? This is very useful if you need small package 1.5 Volt supply for a project.  The independant cells are just slightly smaller than AAA cells. 

Warnings and Stuff
Do not try this on rechargable batteries of any kind as the potential for explosion is higher.  With an Alkaline battery this instructable is quite safe, but still take care when separating the seam of the outer metal package.  Do not use power tools to disassemble. Also, watch your fingers on the metal packaging as this can cut you if care is not taken. 

Hacking the 9 Volt for it's Prize
Check out the photo's to see the disassembly steps.  It goes, pry end crimps at the seam.  Then pry the seam open and remove the shrink wrapped cells. Now cut open the wrapping.  Finally, cut the metal tabs that bind each cell together.

You're done.

Final Notes
Notice that when you disassemble everything you also end up with a 9 Volt battery connector?  This in itself is cool.  Check out member Joshmt2012's instructable http://www.instructables.com/id/Free-9-volt-battery-clip. He provides a great instructable on this.

Check out the last picture.  This is from a cheap 9 Volt battery.  Very different way of arranging the cells. I have never cracked one of these open so I don't know if they can be separated.  My feeling is they are held intact by the outer fused shell. Eventually I'll give it a try and post an update here.  

Further note, the more popular brand name batteries use the six cells as shown in the main photos. These are the ones you want.

Before i injure myself attempting this, is it real?
Jason Bedard (author)  pipsqueakboy1 year ago
Yup, it's very real. Just as shown in the photos. The only step to watch for injury is in taking off the outer shell. It's sheet metal and therefore the edges can cut if care isn't taken. Leather work gloves can protect hands from such cuts.
Ok. Im just making sure it wont pour acid all over my hands.

Oh, and there's no oily or waxie residue as some might suggest. Well, at least not in the twenty or so batteries I have taken apart. Also, shrink tubing the cells is not necessary. Just saying.
At least two things here, 1- removing the case of any battery is a bad idea! That oily or waxie crap is Full of crap you don't want on your skin, use gloves! 2 If your going to do this then wipe off each cell with an alchohol wipe and then slide a piece of heat shrink tubing around it and set it with a no flame heat source; hair dryer on high. Cut the extra off the end and they can be stacked or put into any number of configurations with out the risk of case shorts. Hope this helps in some way.

this is really creative! is there an ible for AA batteries? my 360 controller batteries die too fast XD
Try one of those giant flashlight batteries. I think that is what is in them.
or D?? idk all the types of batteries....
C batteries?

I have an old stylus for a pen-pad and it requires AAAA cells. If only I knew that before I threw it out xD
Hello, I wasn't sure if you were aware, but the batteries that are in there are AAAA batteries. Well, that's what size of battery they are.
Jason Bedard (author)  StumpChunkman2 years ago
Yeah, this I was aware of however I must admit I never thought to mention it. I never use AAAA cells so they're no where near top of mind or me.

Caution is necessary if using these as AAAA for those cells have reverse polarity. Mark the positive Voltage on the salvaged cells and install backward to how regular batteries are installed.

Thanks for your feedback.

To clarify my own clumsy sentence above, it is AAAA cells that have reverse polarity.
