When did Eveready start making their batteries this way? I don't know what radio I found this one in but I have had it for several decades I think and I have never seen one built like this before.

Never seen one like that before. Are you sure someone didn't make up the battery. Soldering doesn't have the quality I would expect from a manufacturer.

Looks homemade.

The guts were definitely home made.

A factory wouldn't have wasted the snap connectors, and metal cases around each set of cells, but rather packed them all together, sealed in special paper.

Googled the manufacturer and part number....still being made. Richard

True, but not like the one in the picture.

While it doesn't seem likely, the cover does have a zip code so is after July '63(actually zip was kinda slow to catch on, battery could be several years later)... The 9v are probably from the early '70s and are Eveready as well, seems like a lot of quidences to me...

That is truly weird. My experience has been to snap them in series so I get B+ Voltage levels like 90V. Once or twice at work I filled a 6 foot workbench from end to end with series 9V batteries, and was able to draw some nice big blue arcs off the end terminals with long leads from end to end! Zap!

The Energizer/Eveready datasheet does say that they are currently manufactured from 54 cells, nine parallel strings of six series (1.5v * 6 = 9v) cells so it sounds like that is, indeed, probably how they still currently build them...

http://data.energizer.com/PDFs/2356N.pdf

As to the original question as to when they would have started doing that instead of being made from six cells of the proper size (as I'm sure they did at some point, way back in the day,) I have no idea, though...

Hello guys
Wow I am wondering what they use that battery for far in what device

I would guess mostly vintage battery operated tube radios. :)

Probably also a few other random old things like vintage geiger counters, etc.

I've never seen a battery tube radio that used more than 7½v to light filaments and a much higher voltage battery(45v-90v) to operate tube elements...

I vote home made, the quality of the solder joints is horrible.

No question home-made, and wired in parallel must have been to provide nine volts at some serious current. I can't imagine however what solid state radio circuit would require that.

Hello,
Was used on this Magnavox FM-90, early sixties.

Regards.

I would bet a regular nine volt battery would power that radio just fine. Ten small signal Transistors just wouldn't normally require much in the way of current.

I still say factory, wasn't like Union Carbide was planning on anyone takin' it to the County Fair...

Highly doubt factory;
as I mentioned above, they wouldn't waste the metal cases, nor the battery snaps, but rather just connect all the cells together, wrapped in their special brown paper.

I think the exact opposite...

They wouldn't bother to do a special production run for a limited production specialty item but instead take standard batteries from the regular mass-production line, solder them together, put terminals on the top in a case of some sort and charge a small fortune for it. :)

It would light a 9V series string of battery-type tubes for a good long while.
