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?

Same. Temp sensors, flashlights, game controllers, thermostat, whatever. Haven't had any issues.

The only time they suck is when a device wants an odd number of batteries. And my charger only works with tandem batteries. Not really sure of the implications, but charging two batteries with significantly different charge makes me nervous.

There are battery chargers that allow charging an odd number of batteries, even single batteries. I have a charger that is powered through USB, similar to the following:

The one I have has two power inputs: an USB-C and Micro USB, so it can be powered by any of these.

Idk, I use one that charges 8. Both double and triple A's

Always have spares in the charger ready to go
