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?

Eneloops are about the best rechargable AA and AAAs you can buy, they last close to forever. I've got some that are a decade old and still in use after thousands of uses and still about 80% of original. You chose well.

And it's fine. I used to use them a lot for GPSrs. A pair of eneloops lasts about 8 hours in an Oregon. A pair of decent branded Alkaline AAs lasts about 7-8.

The voltage is not an indicator of charge life when you're comparing different chemistries. The reason you're seeing low charge is that your device is not calibrated for rechargables. In things that are, they have settings for both so you can select which you use. If your thermostats don't, then they'll always removed about anything other than Alkalines.

A consumer advice study in the UK actually found Ansmann batteries to be the best by quite a bit, with Eneloops in second

Never heard of those or seen them for sale, and I'm in the UK

Not your fault, but doesn't mean it's incorrect. I used to work in procurement, so I keep up with this stuff.

The consumer organisation is which.co.uk, well worth the subscription price

Ansmann are so popular, you can't buy them from Amazon or they'll be fakes. Stick to places like cpc.co.uk

Always removed about anything else?
