While looking for uses for old disposable AA batteries, I ran across the Batteriser from 2015. Clearly, it was a flop of some sort, as I am posting in 2024. What happened? Are there any iterations that do work?

Also, are there any uses for old batteries?
Rechargeable AA batteries have become much more accessible… And imo far fewer devices that we use take replaceable batteries. It’s much more common for devices to just have built in rechargeable batteries.
honest question: when was this not the case? I used rechargable batteries in my gameboy in the early 90s.
Batteries as well as rechargers are dirt cheap for well over 2 decades
Because rechargable batteries before nimh sucked for many use cases - they were good for the Gameboy as you charged and used them straight away at high draw, but try using one in a low power device like a remote or wall clock and you’ll find it is dead in a week despite minimal actual usage
