Why aren't there 1.5v AA rechargeable batteries? (lemmy.world)

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 finally bought some rechargeables again this year after shunning them years ago but that's just because I 3D printed a bunch of Christmas lights that have battery powered RGB pucks inside them.

Funnily enough, I started with all alkaline until the rechargables came in the mail at which time I replaced half of them with rechargeables which have already died and needed recharging before the other half with the original alkaline have needed to be replaced.

Previously, the only really good use I had for them was with my old Xbox 360 controllers since I could have a pair on the charger while using the other pair.
