What happened to the Batteriser? (midwest.social)

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?

There are, but to use them as a replacement for NiMH/Alkaline cells, they need voltage conversion and typically have a built in charging circuit so you can charge then via USB-C for example. Theyre expensive, have a similar capacity compared to NiMH and can't be charged in a regular battery charger.

On an other note, there are 1.5V lithium batteries (non-rechargable). They supposedly have a higher capacity and last longer.

And then there are 14500 Li-Ion cells that are about the size of an AA cell but run at 3.6V.
