I didn’t know it was a fraud until the claim included converting 1.2 volt rechargeable cells to 1.5 volt cells.

Why would you think this makes it a fraud? I can easily build you a circuit that can do that with no problem.
It’s just a form of a voltage doubler circuit that’s been around for years. There are even IC’s for it.
The big deal (and it is a pretty big deal) here is that it’s been micro-miniaturized to fit over a battery.
The circuit design is not what caused me to be skeptical. I hadn’t considered that the miniaturization technology required was available. In light of your confidence that it is available I withdrawn the fraud assertion.
