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?

    Huh, I use exclusively rechargeable batteries in everything. Works great.

    Except the smoke alarm, that one complains if I don’t use lithium

      Google seems to have set their nest protect units to need six lithium AA non-rechargeable cells. Which is 1.8v, not 1.5v. You put in completely fresh batteries verified with a multimeter at above 1.5v (1.58v iirc) and they’ll complain about it.

      I bought lithium rechargeable and they’re 1.5v. Which seems reasonable. I wish all of ‘em would be one standard.

      Feels instead like we have AA-, AA, and AA+.
