Default Replica U12 battery

Ok, I know I've gone totally mad, but just in case anybody else want to turn their modern AA batteries into something that looks more vintage, then, I've attached a couple of pictures for you

Just make sure the image is the right size before printing (I've written it on the side)

Regards
David

Wasn't what is nowadays known as an AA once designated U7 ?

Hi Darren,

So much of my youth was mis-spent with batteries that I'm pretty sure on this one... the U7/SP7 are now known (by most people anyway ) as C cells, while the unsealed version of the modern AA had in my day acquired the cumbersome designation of U12/D14. To complete the list of familiar types, the D cell was the U2, while the AAA was the U16.

Nice cover, David: I may just print a few of those for a little Philips radio from about 1960 that uses the things. Not worth it for the cordless mouse

I seem to remember AA, C and D were SP7. SP11 and SP2 (or HPX for the zinc chloride types) respectively, but could be wrong.

I'm 99% certain the AA was the U7/HP7 and the C was once the U11/HP11 .

Maybe a new thread elsewhere would be appropriate on this subject ?

Ah... yes, my memory is indeed going! Sorry about that,folks. Now that I've kicked it, yes, the AA was indeed SP7 and HP7, but a tad anomalously U12/D14 in its basic unsealed form. So presumably a simple U12 earlier, and never U7 so far as I know. And, yes, C cells were U11, SP11 and HP11...

I found this version of the U12 in a very old novelty torch at the dump years ago. AA/HP7.

Ooh... I don't suppose you'd like to soak that label off and scan it for me .

Hello Dave,
The label is hanging off anyway due to being so dry. If you PM me with your address I can forward it to scan at your leisure and return.
Regards John.

In the 1966/7 Ever Ready catalogue there are:

D size: U2, LPU2 (the designation SP2 had presumably not yet been used) and HP2
C size: U11, LPU11, HP11
AA size: HP7 and U12/D14. Note the dual designation. It's also interesting that the HP7 is listed twice, once in High Power Batteries and again in General Purpose.
AAA size: U16, HP16

Yes: we may just have been imagining the SP7, I don't recall meeting a sealed version at all, or perhaps there was one rather later. The little hoard of defunct cells here includes a few LPU2s, a couple of U2s and a set of five SP11s found not so long ago in an early cassette recorder. I think John's U12 cell must be from the very early 60s or before, as all those I did things with in infancy were U12/D14s

I've attached another U12 cover that I've made from John's (Heatercathodeshort) battery

I think this is a later version than the first one

David

Brilliant work Dave! Such a lot of work for such a tiny label.

Very sharp. Sorry about my absence--I managed to deepsix the hard drive that had all of my battery covers on it.

Fortunately I was able to recover 9/10's of them. But it took over a week and many hours each day to back everything up.
