I bought a bunch of eneloop pro, but using them in connected thermostats is always displaying "low battery" even after just fully charged. This is when I discovered that they are actually 1.2V

It really came as a surprise, is there a catch? Are they only good for low power stuff like remote controls?

Edit: it seems they do exist in lithium. Question remains why are the NiMH only 1.2v and why are they the most widespread?

The problem with non-rechargeable batteries is how they can easily become e-waste. Yes, there are recycling programs, but I once heard rumors about fake recycling programs that simply dispatches the e-waste to landfills across poor countries, polluting their soils. Rechargeable batteries will eventually become e-waste, too, but it seems to take longer than non-rechargeable batteries... of course it depends on how frequently they are charged and discharged. I have rechargeable batteries (which I use in my wireless keyboard/mouse set, digital hygrometer and a Bluetooth joystick) that have been lasting for years, I even don't remember when I bought them. It's worth mentioning that the battery brand I use is known by their poor quality (Multilaser, a Brazilian company that sells white-label electronics under their brand), and yet they've been holding charge.
