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 have some thermo regulated valves that require 1.5v as well, so for those I decided to go with regular alcaline batteries. Those are still above 80% charge after 1 year of usage, that is why I decided not going with rechargeables for those trvs
