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.
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 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.
I selected all and it's still not enough of a reason!
Bow to Alec! Let Alec consume you!
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!
