The article SEEMED to suggest that A cells were available up there. I would think it odd, since the markets for electronic gadgets are probably similar.

I'm calling your bluff ,I don't think they are available in Canada,and we're none the worse for it.

Y'know, it's a tremendous relief to see multiple articles tackling this question. I thought I was the only battery otaku around . . .

I think the New Scientist article is referring to the "Radio A and B" batteries.

So the remaining question is: Was there a A-cell somewhere between the B and AA in size?

I caught this one on New Scientist's Last Word a month back. A bit of explanation about A and B sizes

Don't forget N cells. In Japanese notation:

  D = UM1
  C = UM2
  AA= UM3
 AAA= UM4
  N = UM5

Not many things use N cells, which are about as thick as
an AAA, but about half the length, but I have Radio Shack
brand rechargable ones and I used to use them for projects
I built. The N cell battery holders also fit the 12v lithium
batteries used in many car key-chain remotes.

The followup covering the *other* B-battery was a little difficult to find on exn.ca.

Batteries are circular because they needed to be for a very long time (you wanted an equal amount of catalyst around the cathode and anode.) Nowadays, they've worked around that, but batteries still tend to be cylinders, since that's what the battery machines make, and that's what many battery sockets expect to hold. Batteries are far too entrenched to try changing now.

Other sizes you see -- 1/2 AA and 1/2 AAA are common lithium cell sizes -- same diameter, half the length. (and, in many cases, twice the voltage.)

I've been wondering lately why no one has made an AA+ or AA++ battery that's square on one side [) or both sides [] respectively, but otherwise the same dimensions. Or AAA+ and AAA++. Plenty of my AA and AAA equipment has airspace around the battery, either being held in with something that looks like a boat dry dock on one side, or simply in a square area touching it only in four places. You could probably get another 20% on the capacity of small NiMH cells if you actually took advantage of the extra space in battery compartments.

But then, if a 9V is actually 6 AAAAs there must be a good reason for having a circular cross-section...

Ah, so that's what those cute little things are! (Model rocketeers who need juice to run cameras, altimeters, etc., often strip the case off of 9v batteries to save weight.)

In a related note: Some rocketeers are looking for "polapulse" batteries -- flat, index-card sized batteries made by Polaroid to put in their film packs -- to run an esoteric launch panel.

You can find AAAA batteries in a 9V battery -- there are 6 of them hidden in the case (1.5x6=9, of course.)

I've seen AAAA-D, and F (There are four F cells in the large 6V latern batteries), but I've never seen an E. The sizes used to run up to J for shortwave radios.

Funky, but the way things are going I'm going to need AAAA batteries soon. I use AAAs for my Palm, IR gamepads, PalmPix camera, Gameboy Pocket, etc, etc -- a slow, but steady, shift from AAs.

Well dammit Cory, don't play games with our emotions like that, okay? Jeblis stepped in and covered you on this one, so yeah - we will let it slide this once but Maynard, you WATCH it from now on....

Sorry, it's after 1AM in London and I'm a little goofy.
