What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

But.. does the mythical A battery exist?

Most "batteries" are in fact cells.

This is why humans make good batteries.

[–] [email protected] 2 points 8 months ago

Humans make terrible batteries, you leave one in a box for 6 months, you come back to a soggy, very stinky box.

Humans are much better as low power space heaters. As long as they have fuel, they’ll maintain a known temperature.

Is a battery with one cell still a battery? Is an empty library still a library? Is an empty breadbox still a breadbox?

[–] [email protected] 10 points 8 months ago* (last edited 8 months ago)

A battery has many faces. A battery has no name.

An A battery is usually just called a 17500. They were used in laptop batteries and such but are now used in hobbies more. Mostly for flashlights, vapes, or Lightsaber replicas.

Right - so that is a photo of an AA battery and a drawing of an A battery.

So if I take a photo of a gorilla and draw Sasquatch next to it I have proof of Sasquatch! This is good info to me.

An AA battery next to a dimensioned 2D drawing of an A battery (7mm grid).

(This is an placeholder image for A battery section of en:List_of_battery_sizes. To be replaced with an actual example as soon as one comes along.)

I think you were right, it does exist, but Wikipedia doesn't have a picture of one they can legally use. For example I found this:

[–] [email protected] 5 points 8 months ago* (last edited 8 months ago)

Honestly it feels like "1/2AA Battery" should just be an "A battery"

[–] [email protected] 1 points 8 months ago (1 children)

Ah - so I need to put the drawing on Wikipedia. Noted!

Anything else that’s needed? Quickly please as I’ve already called NYT and CNN

[–] [email protected] 8 points 8 months ago (3 children)

You could read the text next to it. They have an official specification, and they're occasionally used as cells in larger battery packs, but they never got adopted in consumer products, so you can't just buy an off the shelf A battery. Nobody has bothered to get a picture of one, because nobody actually cares that much.

[–] [email protected] 3 points 8 months ago

Can someone fix this dire state of knowledge?

[–] [email protected] 2 points 8 months ago

Thanks - I’m adding some text now next to the drawing about occasional sightings in Canada, but as they don’t care about capturing it nobody has a picture of it. Hence validating my drawing as the only proof.

[–] can 1 points 8 months ago

No public image at least.

There’s even C batteries, they were known as baby batteries when I grew up, and quite a few ghetto blasters used them

[–] [email protected] 2 points 8 months ago* (last edited 8 months ago)

Funny. I have 3rd-party scripts disabled and it spawns endless search fields.

[–] [email protected] 1 points 8 months ago

That's preposterous
