First put up the site online then you advertise

I think you're talking about this:

https://www.batteroo.com/

The link you provided seems to go to their original campaign. But their website link above shows the new "Reboost" version which is supposedly designed for rechargeables.

In the photo they show using the battery in a remote control. That would be the last thing I would expect these to be good for. A remote sit idle for most of the day, has very low current use and drainage, would likely work down to very low voltages. That's the worst device you would want to put rechargeable in, even without a Batterizer... as just sitting unused the rechargeable would slowly lose charge. Add to that a Batterizer that continuously operates a boost converter and it will sap your rechargeable dry much faster. I don't get it... Please somebody explain the logic here that I am missing....

"Everyone has several remote controls. We can sell lots & lots of Baterroos."

The logic is that people will believe anything if it is told with a good story.
Proof is overrated.
Remember that the next time you want to sell a product.
It has to look good, make people feel good (save energy, CO2, save the world!) the rest is irrelevant.
This era is controlled by feelings, not Logic or Truth.

There might actually be some validity in that, since NiMh cells put out about 1.2v which is too low for some gear to work well.

The problem I always find with NiMh though, is increasing internal resistance after a few recharge cycles.  It's usually not so much a question of o/c voltage alone, but that once the cell gets a bit tired the already marginal 1.2v drops to less than 1v under load. In that case trying to step-up the output will actually make things worse, not better.

I try to use lithium wherever possible these days. I know there are fire safety issues but hey, they perform so much better. In the case of lithium it's more likely the voltage is too high for equipment designed for alkalines, though. A batteriser to drop 3.7v down to 1.5 would be real handy, making lithium retrofit easy. Not likely to be a consumer product though, too much risk of costly or dangerous mistakes.

The problem I see is if this device works and lets you drain rechargeables more normal then you stand a better chance damaging the battery for reuse.

If it prevents reverse charging of the cell then it's an improvement. NiCd & NiMh don't mind being flattened right out, what kills them is cell reversal. If these prevent cell reversal then it's a win.
