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?
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
