Remember Duracell’s PowerCheck? The idea was that a strip built into the battery would show if the battery was good or not. Sure, you could always get a meter or a dedicated battery tester &#…

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 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 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.

Neat!

I didn’t bother watching the video, so I guess the reasons were pretty obvious.

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.
