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?

I feel like the only batteries I use are for the firealarm and remotes. Oh then I have oddball things with watch type batteries but as far as I know their are no rechargable equivalents.
