Gregory's Server@TechConnectify I remember how similar batteries appeared around 10 years ago in Kazakhstan. Batteries were from Duracell Ultra lineup, so they had slightly different design, but the fundamental principle was exactly the same - you press the two buttons with all your might and hopefully get the reading on a small yellow bar. At least they made the buttons bigger, but I'm not sure if they actually had bigger contacts or they just made the white circles on prints bigger
And similarly to powerchecks from early 2000s, these didn't lasted for long and disappeared from the shops - not only because this wasn't that useful, but also because at this point the AA and AAA single-use batteries were already mostly used for low-power devices like TV remotes and clocks for which checking the charge was arguably even less useful
