Nice try, Alec Watson…
I mean I’d rather Alex get the direct views than this weird hackaday article that’s just a description of his video with a link. Not trying to knock hackaday but this is real close to freebooting.
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.

I think the reason we haven’t seen that is that NiMH rechargeables have fairly stable voltage during discharge while alkalines don’t.
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.
And pairing them correctly for paralel charging too!
I think all of your points were covered in the video, sometimes almost verbatim.
Neat!
I didn’t bother watching the video, so I guess the reasons were pretty obvious.
How dare you ignore Alec’s video? 😤
Select one or more of the following.
- Too lazy.
- I assumed it was a rickroll.
- Figured the video was just another version of the article.
- At work and didn’t headphones handy.
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.
This guy is great. He can make anything sound interesting.
He makes everything sound interesting.
Ftfy
It broke too many thumbs.
I was a kid then, but I remember that I had to push so hard my fingers hurt… I used a multimeter.
as a kid I would shove them up my nose not to be seen again until out they would pop from the other side…miraculously charged.
Let me introduce You to these spent uranium fuel rods.
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…
That’s enough YouTube videos just recapping an article. But I agree it’s lazy
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.
He used old batteries, but I actually had new Duracell batteries with this feature very recently, in 2022 or so (Germany).
You could’ve saved him so much movie magic!
It never went away. I have a duracell battery with power check sitting next to me on my desk
What sizes are still sold with the on-battery tester? AFAIK it’s now only available on the multipack box.
I think it was a 4-pack
also germany, actually
So the US said later, indicator, while Germany said $punchlineRemainderPls
Does anyone remember the battery testers that were built into the packaging? I think they were based on the same concept.
I do
It failed often enough that it wasn’t all that useful. A cheap battery tester is better. And for 9volts you can also use the tongue test, lol (don’t really though). My grandfather used to do that all the time.
The tongue test works great. Be warned, though, that a full battery will make your tongue go numb. It’ll feel like you have a big hole in the middle. Try it.
Ouch, I never had that problem, but I only barely touch it, lol. It’s a little shock and slightly numb briefly. But fortunately I never had full numbness that lasted more than a second or two. But I haven’t done it in a long time since I have a tester now. 😁
What’s wrong with the tongue test for 9 volts? I know it tickles some but is it actually harmful? I’ve been doing that for over 30 years…
It’s not much power, so it’s not likely to cause major or permanent damage, but it may affect others differently and could cause burns if left on too long like if someone is less sensitive and doesn’t think it’s live.
And if the person is grounded and if they touch the hot side of the battery first there’s a chance the charge could travel through the body rather than just the tongue. It’s not enough to affect a heart, but might disrupt a pacemaker or other embedded device.
And of the battery is leaking, it could cause permanent damage from chemical burns from the alkaline and poisoning from heavy metals which while unlikely to be deadly with just one battery, heavy metal poisoning is cumulative across a lifetime.
So under ideal circumstances it is safe, but there are always risks with electricity and toxic chemicals, though relatively small.
Everytime i test a battery like this, my wife just shakes her head and reminds me that I’m definitely from Kentucky lol
My dad used to just put them on his tongue for a power check. Not entirely sure how that worked. Personally I just use a multimeter.
You can do that with the 9 volt batteries and feel how much “tingle” they have, but never heard of it working with aa batteries. Wouldn’t he have to stick the whole thing in his mouth to complete the circuit?
It’s pretty shocking, but I can fit 2 Ds in my mouth.
ah, I love it when mothers teach their kids valuable skills
Your mother must be so proud.
-Are you testing batteries again? -(with my mouth full) nogh
I did know a girl in college …
Even if you did (don’t eat batteries), the voltage range is much lower and you probably wouldn’t feel anything.
Yeah. Doesn’t make any sense honestly. I think he thought he could power check it but didn’t understand the actual mechanics of how it works. Glass onion eh.
There were cheaper ones with a tester attached to the box, maybe they were energizer?
Oh, I remember that! It was inside the little packet
We just can’t have nice things
IDK. It never worked that great and TC guy makes a good case why it went away.
The battery industry made rechargeables good instead of decorating disposables.
I remember having to squeeze hard to make the ends contact
I had to squeeze so hard it hurt my fingers. I see no loss here.
