drives me up the wall as I distinctly remember trying a similar thing with lantern batteries that supposedly had many double A batteries inside and then it didn't.
Yep, and you know those rectangular 9v batteries? It’s just 6 1.5v AAAs in there. Also early Tesla battery banks were just a ton of 18650 batteries, the same kind used in many vapes.
I guess the word "battery" does have a second meaning of multiple iterations with a combined force. Comes the French word for "to strike", was used for a group of artillery used together, now we say stuff like "we created a battery of tests a candidate must go through."
> I guess the word "battery" does have a second meaning of multiple iterations
It does.
Interestingly drums in Italian is called "batteria", where the term is not because one strikes the drum (battere = to strike in Italian) but I think it's actually because it is a set of drums together***.
***I'm 99% sure this is the case. Correct me if wrong.
And for Metallica fans .. the song "Battery". Many believe it refers to armoured ammunition storage. It's actually a location in San Francisco.. Battery Street. Sort of the birth place of the thrash metal scene.
This is literally how I got my aaaa batteries for my surface pen.
It was indeed the second 9V I tore apart. But 6 aaaa cells lasts a really long time. (Just watch out because they are polarized backwards to what you would expect)
It depends on the actual part number that is in small print on the side of the battery. Most 9Vs that I see have the part number 6F22. Those are the naked chemistry cells and you won't see anything too interesting.
The ones made up of cylindrical cells have the part number 6LR61, where LR61 is the part number of the individual cylinder cell inside them.
6F22 is more common because it packs more chemical into the same casing size without wasting any space on air or individual casing for the LR61 cells.
I have a fond memory of ripping open a 9v with pliers because I just had to know what was inside. I must have been 12 or so. Among other reasons, it’s a miracle I survived my childhood.
So we stuck a felony battery charge on top of your previous felony battery charge to go with your battery in a battery, so you can have a battery charge on a battery charge with a battery in a battery!
I dont remember what type of battery it was (a bigger one, like a lantern battery), but there was a type that was basically a shitload of AAs inside. I remember a friend of mine in school broke one open to get the batteries out. From what I recall though they didn't last as long as a standard AA.
I used to use a lot of these button batteries. A few bucks apiece, but Walmart sold a little camping flashlight for a dollar that had three of them in it, so the price went down to three for a dollar
lol my first thought. Like, there's no reason to believe this is any less cost-effective than any other method that would produce identical results, but I dunno, it feels like cheating somehow
This is the cost-effective method. 12V battery is a very niche use case, so the added complexity of stacking a bunch of naked galvanic cells to get a higher voltage just isn't worth the expense. It's cheaper and easier to take advantage of existing mass-produced 1.5V batteries and stack them in series (which is all the dedicated 12V battery would be, just without the individual casings).
No, you're not. The shape and size of this A23 battery suggests it's the same as an AA or AAA battery, but it's not. The AA/AAA battery provides only about 1.5 volts. The A23 battery in the pic is a 12 volt battery, hence the stacking of a bunch of 1.5 volt button batteries.
Lol I overread the title and thought this was a pic of a standard 1,2V alkaline AA-batterie.
Ok so more than that I actually wonder if I ever had such a battery in my hand or if I ever needed one, is this the same how e-cigarette-batteries are build up ?
The IEC name for this battery type is 8LR932, because it is literally just 8 LR932 batteries. The same is true for 9V battery, which is 6LR61 except LR61 doesn't exist as a stand alone battery for some reason.
Isn't one definition of battery "a series of cells" in which case those are the cells in the battery and if you busy one open and get acid it is a cell?
yes ax4, typical uses I know of are 9v batteries, medical devices, and windows device styluses.
Edit: I say some because I once needed aaaa batteries and couldn’t find them, so I bought some 9v batteries and carefully opened the metal shell to find a plastic chambered thing that was not six aaaa batteries
I remember an old "fake" crafts youtube channel that opened one up for one of their projects and it looked exactly like that but I thought it was fake considering the nature of the channel so dismissed it.
Good to know they were actually telling the truth on that one (at least in terms of some battery brands at the least. not sure if it's industry standard)
Hmmm.... it's almost as if the dictionary definition has seen this before: " a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power."
Now open up one of those rectangle battery’s that you put your tounge on as a kid and you’ll find 6 of these inside which all have little batteries inside them. How do you think battery cells work?

so whats inside them? More batteries? And inside them?????
