What with the weird freebooting article? This ‘article’ is just a description of Alec’s video with the clickbait cranked up to ten. Gotta love a major corporation using small creators’ work for free ad revenue…

I'm fairly sure that the image is even a screenshot from the video. Uncredited I notice.
It is, I just watched the video an hour or so ago.
edit: In fact, until I read this thread, I didn't notice the URL and thought this was a link to the video.

This is how hackaday posts have been… for like a decade. I guess it’s somewhere between articles and link aggregator.

Video on technology connections: https://www.youtube.com/watch?v=zsA3X40nz9w
"Wait, is that a Duracell battery check?"
Oh man that transition. Chef's kiss. Amazing

But the video purports that normal people don’t really test batteries.
Yeah, it was a novelty that increased the price to manufacture and didn't actually add anything of value to users.
Either you put batteries in something and they worked or they didn't, and if they stopped working the next step is try different batteries whether or not the little gauge showed it had charge left.
Now if it was added to rechargeable batteries, it would be pretty useful because tou could do something with the knowledge of a battery being at 50%. But a lot of systems with rechargeable batteries have them built in and some other way to show remaining charge like a percentage on a screen.
Now if it was added to rechargeable batteries, it would be pretty useful
I think the reason we haven't seen that is that NiMH rechargeables have fairly stable voltage during discharge while alkalines don't.
I think all of your points were covered in the video, sometimes almost verbatim.

It was pretty useful as a kid for feeding my Gameboy and Game Gear with batteries I rescued from the junk drawers of friends and family. If they were low, I knew I had to save more often to avoid losing progress if they went dead while I was playing.
I concur about rechargeables - it doesn't seem common for devices that take AA or AAA to have a battery gauge and it would be nice to be able to check the level on my rechargeables stock so I can know if I should top them off without needing to put each of them into the charger.

I was a kid then, but I remember that I had to push so hard my fingers hurt... I used a multimeter.
Well the pros and cons of the multimeter are addresses in the video! He uses a meter on a dead battery and it still shows a deceptively reasonable voltage when not under load. The built-in tester draws more current.

It turned out that batteries randomly lying around are always empty. Functioning batteries are still in the device it's operating or in the box it was sold in.

I have a really distinct memory of finding a bunch of these in a friend’s house when I was a kid and every one was empty. After watching the TC video I think it’s more likely I just wasn’t pressing hard enough and had no way to know that. Anyway, I can see why they stopped making them.
Yea, you have to press till it hurts, lol

Did the power check work or was it snakeoil I remember trying to see it while hurting my hand.
It did, see Technology Connections' latest video on it, he explains fully how it worked. Quite clever tbh.
Although, he admits in the video to "faking" his footage of it working, by using a off-camera heat source. (His batteries were quite dead.)
But, as someone that lived through this time, they did work, as long as you pressed hard enough in the right places. It was hard to tell if the battery was dead or if you weren't pressing hard enough
If you watch the whole video he does it more "for real" later on, plugging the casing into a power source to simulate a battery discharging.. Plus I've had some of these PowerCheck batteries, and they were not old, it was like... 2017? So maybe they rebooted it for a short time at some point?? Anywho, if you pressed really hard it did work I think, but also I think I was doing it wrong for a long time as well lol

It broke too many thumbs.
This guy is great. He can make anything sound interesting.
He makes everything sound interesting.
Ftfy
He used old batteries, but I actually had new Duracell batteries with this feature very recently, in 2022 or so (Germany).

If they are not rechargeable, they don't make sense, you just use them and throw them in the used up recycle pile. And if they are rechargeable, you already have a charger that does it.
It also has to be a waste of some resource that is rare to not use up and throw away like this.
They checked out
Does anyone remember the battery testers that were built into the packaging? I think they were based on the same concept.

It never went away. I have a duracell battery with power check sitting next to me on my desk
