Does anybody know where I can purchase a AAA dummy battery (or many) online?
thanks!

Can you provide a little more information please? Are you substituting a 'wall wart' power supply for battery power, for instance?
Are you creating props for a show?
These have different answers.

The "dummy" AA (not AAA) "batteries" that I have are used in place of *real* "batteries" as "place holders".
E.g., 8 alkalies + 2 dummies = 10 NiCd's
For that particular application, I would contact my friendly local machinist. Have her part off some
1/4" copper tubing to the proper length, solder plugs into both ends, clean it to within an inch of it's life and then place it into an electroless tin bath for a day or so, then clean it off and use heat shrink tubing to insulate the outside.But that's just me.

Why not just turn down a solid *bar*! :>
Actually, the ones I have are castings. Look more like a (flat) bar with two discs on either end. When I first encountered them, they were half way to the trash bin before I realized their significance!
Whiskered (shorted) NiCd cells are good for this.
If you want to make sure, bridge over the seal with some solder - you'll need plumbers flux to solder the stainless jacket (alusol also works).
Too much trouble..use aluminum rod cut to length and shrink wrap.

Cu tubing is cheap and available everywhere.

From:
"Aluminium oxide is an electrical insulator.."
"Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of alumina (4 nm thickness) forms in about 100 picoseconds on any exposed aluminium surface."
One would have to install them *very quickly* :)

Yes, I was being facetious. ;-)
I once (as a kid) asked for a length of "cold rolled" to use as an axel in a go-kart I was building. Dropped by his (machine) shop the next day to find a guy turning my axel -- complete with keyways, and threaded ends predrilled for cotter pin locks! I suspect the labor in that axel was worth more than the rest of the go-kart! :-/
Kinda like once you play with a router you find yourself using it in place of a *saw*, etc.
My expectations were not adjusted properly!
May that remain the worst surprise you ever get. :)

Oh, drill presses are *much worse* than lathes WRT misuse.
My drill press has served as a buffer, a grinder, a paint mixer, a sander, a wire wheel arbor, a polishing jig and (thinks...) .. a drilling machine.
That was all *last week*.
Not that there is anything *wrong* with that...

just saw a groove down the side of the dowel,lay the wire in,and fold over the ends. If you want,you can get fancy and coil the ends before folding. You can even drive screws into the ends,wrap the wire around them.

isn't an "axel" a ballet or ice skating move?
an "axle" is what wheels are mounted on.

No doubt. A throwback to misspelling "nickle" as a kid :-/
Of course, if we want to get started on a (periodic) USENET (mis)spelling rant... :>
I, for one, am sick of this constant stereotyping. There are MANY male machinists out there and MOST of them got to where they are on TALENT, not just good looks. I don't know how many times our own lathe operator, Swedish Kurt, has suffered the sexist jibes of visiting female business types.
The insulting, sexist garbage talk still hurts me when I think of it. "Hey, BLONDIE..where's your parting tool" and "Is THAT a Norse Taper?" make me cringe.
There's WAY too much of this going on and it can NOT be all blamed on six martini lunches by those overbearing wenches.
Please, it's within your power to end this here. Think how YOU would feel being treated as an object by thoughtless and uncouth business suited TRAMPS.
Let's give the minority males in the machinist trades the respect they so rightfully deserve.

My initial smartass answer would be Rayovac, Varta, or any other crappy non-alkaline battery! :)
Otherwise, sorry... can't help.
Or a German male's text message signature.
Except that "nickel" is correctly spelled either way. Grating, but that's the way English goes. ;-)
Why not? DimBulb will join in any minute with the wrong answer, as always.

** That is wrong headed thinking - as usual for you.The " end point " voltage for Ni-Cd and alkaline cells is the same at 1 to
1.1 volts - making any difference in the initial voltage irrelevant.Hence one use the same number of cells.

I went digging through boxes in the garage and managed to find a few of these. I was hoping for a manufacturer name, model number or some other form of identification.
No luck on that score.
But, they are fabricated as I mentioned (elsewhere this thread) except appear to be either conformal coated or a *clear* "shrink tubing".
Appear to be die cast. Inscription reads:
DUMMY BATTERY To be used with 8 standard or alkaline penlight cells. Korea
with the initials "DJ" on the reverse side.
