An orthorhombic (brick-shaped) 9V battery with one male and one female terminal. Decades ago about the only use for them was transistor radios, so I’ve always called them “transistor radio” batteries. But most folks nowadays would be puzzled by that term. What’s the proper name?

9V battery.

Calling them a 'stacker' or 'sixer' doesn't go far.

Should do fine just calling it a nine volt or PP3.

“Nine Volt”

Both Duracell and Energizer just label them as "9V." The fine print on the rear of the Duracell has a long identifier, but I suspect that's just for formal, internal use.

I just found this on the web:

“The alkaline variant of the 9V battery is also referred to as 6LR61 and 006P. Other industry names for the 9V battery can be Duracell MN1604, Rayovac A1604, Energizer 522, Varta 4922, MX2400, 1604A, Radio Battery, Smoke Alarm Battery, 9V Block, and Krona.”

Yeah, I’ll stick with “9 volt”.

I call 9V batteries that I use in my devices, “Dead” or “Dying”.

The OP reminded me that I also grew up calling them, transistor batteries.

PP3 was the name and description a long time ago.

I was trying to help identify some ancient and obsolete electronic junk for an Estate Sale and couldn’t figure out the needed battery size. I learned from a search that PP “Power Pack” was actually a series of different sizes, thus PP1 and PP3 and up was a series of sizes going up from there.

As a young man my best friends Dad was a WW2 Vet Electronics and Radio guy. He always called them Transistor Batteries. He would “test” these by sticking the contacts on his tongue. He finally convinced me to try that, I hated it! I quickly learned to use a Volt Meter to check the batteries. Clyde Smith was his name and he introduced me to Ham Radio.

What he said. And you test them on your tongue.

It’s always been a 9V to me

Have you all noticed that AA batteries seem to have taken over for most applications where in the past it would have been several D, C or a 9V?

It doesn't matter, they still won't come when you call 'em...

The only thing that matters is what they taste like.

Tongue test. 9V battery or transistor battery as others have noted.

 
I've been using the Lithium 9Vs lately. They are more expensive, but in return they last longer, and you can leave one in your device for a long time of no use, and they will not leak that white crap from the terminals like alkalines will. I also have gone to the Lithium AA and AAA cells for the same reasons, where I don't run rechargeables. The AAs and AAAs and not proportionately more expensive. Energizer, for one, makes all those sizes in Lithium.

This isnt at a bad thing. I worked at getting my personal electronics on AA's when still in USAR so that I could swap batts when low from one item with less priority to another that needed to work. The only glitch was Surfire and those C123's.

After that things moved to AAA's and that worked well as lights etc downsized and were still more powerful. That got me up to the 18650's with USB recharging being the common denominator, and a power pack to handle the phone, flashlight etc with cords. I can jump the wife's tablet if needed and her car has ports, too. I keep a recharger plug in the truck, we aren't without options and a common backup power source. Hard no on button cells. Cheaper to toss that junk in a thrift store bin and by new at the replacement cost of the cells alone. Learned that lesson long ago, try finding a "N" cell for a first gen Aimpoint.

Now its either got a USB rechargeable cell - which can last hundreds of times longer - or it's not an option. The LED weapon sights are all 2032 IIRC. Same idea - make it a spec and it won't be an issue unlike all the speciality junk Chinesium.

About the only 9v in the house now is smoke detectors or an old Radio Shack needle display voltmeter - because digital ones aren't all that. And I stuck with the Ryobi 18V batts for the tools - they sit 28 days a month, Im not "investing" double just to brag over the name. Control your battery footprint and it's all good.

AAAAx6

Yep 9 volt. Have one in my safe combo lock. I change it once a year although they always test good once removed.

9 volt tongue tested till getting a voltmeter.. Then did not have to worry about the after taste. ...... drill sgt.
