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’ve reached the point of absolutely hating rechargable batteries. Between their ghost discharge, and the fact that I don’t go through as many batteries like I used, using normal alkaline batteries seems to be the best for me anyway.

      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+.
