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?
But there are 1.5v rechargeable AA batteries out there.
Yeah but they’re a cheat. They’re lithium cells regulated down to 1.5v. Good ones are rare, when you find good ones they’re generally expensive and because they’re regulated down you generally get 100% battery showing until just before they fail.
I used them for some voltage sensitive stuff, but finding a brand that held a good charge for more than even 50-100 charges was hard.
Nimh is much better for anything that won’t be upset about the voltage too much.
Thanks, indeed. I was searching NiMH 1.5v, but indeed in lithium there are 1.5v
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
Yeah, I have some EBL brand 1.5v rechargeable batteries since the VR handsets I own are pretty sensitive to low voltage. They were unfortunately a bit more expensive than regular 1.2v rechargeables.
