9 volt battery is full of AAAA's

If you open a nice alkaline 9volt you'll find it is made up of 6 AAAA batteries. I think they may be a tiny bit shorter than real AAAA but usually work fine. Let me know if it works for your LED light.

Being the playbaby I am I gave this a shot. I tore open an energizer and sure enough they are AAAA's but the little contact points did not quite stick out far enauogh like you said making them a bit shorter and they wouldn't work. Probably with some playing around I'll get them to work.

I give up. What is a AAAA? What's the voltage (1.5?) - what's the size and shape? The last time I opened one up (around 1960) it was made of rectangular pieces of carbon about 3/16 thick. I used them to build a carbon arc light, using a 120v cheater cord and using the top bunk bed as a work table. It sure was bright while the explosion was going on, but little sparks shot all over the bed and burned several inches through the mattress before I got them out.

But I learned a lesson, though - next time use my brother's bed.

If these AAAA things are cylindrical, maybe they can be fitted with an led or somesuch, and slid down a rifle barrel for inspection.

AAAA is just smaller than a AAA. And yes they are 1.5V and this thread is related to one about led flashlights. I tried the experiment and the cells in the 9v didn't have big enough nipples on the ends to make proper contact in the flash light.

Try soldering a maglite solitare bulb to a fairly stiff wire, like lamp cord and slide it down the barrel, or in my case inside car doors to inspect. you'll need to adapt an AA to lite it. As far as the nipples no being big enough to work in the LED light, try leaving them out in the cold for a while.

Funny Mitch I didn't catch that at 1st .

I was cosidering filling the space with something conductive. A 9v would be much cheaper than 4 AAAA's.
