@TechConnectify Oh delightful! I always wondered how they worked (and why they were designed to destroy finger(nail)s).

@TechConnectify yes i still buy disposeable batteries. mostly for my gameboy pocket (ewww) with everdrive (aie), which according to most people doesn't work but it actually does; but only if your batteries can stand a high peek voltage when booting, which AAA's are not designed to handle at the best of time.

and since you can't leave your batteries inside, the battery check would come in kinda handy

@TechConnectify They still make those “powercheck” batteries in Europe though. I remember this feature presented as something “new” in 2010’s ad even.

@TechConnectify it's a great video, and i completely agree on the uselessness of the feature.

But did you really use one time batteries in a walkman? I thought that was the moment to get rechargeables for everyone

@TechConnectify

What an exciting and important development in battery technology I said to myself at 9 years old, I then slapped a metallic bracelet onto my wrist and deftly avoided burning a hole in my tongue with warheads before venturing out into the woods with a pack of other kids unsupervised for 12 hours.

@TechConnectify I could've sworn I had another brand of battery fairly recently that had this battery meter on it (like, as of 3 years ago)

I forgot about them until this video, and now I wish I knew where they went so I could see if they were from 2003!

@TechConnectify Video Idea! Mostly as I want to understand why this happens. So I collect 80s/90s RC cars, and so often we find that not only have the batteries leaked, but the blue candy powder has somehow invisibly travelled along the power cables deep into the toy and begun eating away at the circuitboard. It seems to eat it from the inside, expanding the board which crumbles and can be scraped away until nothing is left. Quite frustrating. I'd love to know why this happens.
