I find that the battery life seems fine, but I haven't tracked it closely.

I have noticed a difference between Duracell coin cells purchased at Costco and Amazon Basics coin cells. The Amazon Basics ones didn't last long at all, the Duracells seem much better.

The newer dimmers (STYRBAR) use AAA cells instead of coin cells, so I'd expect them to last a lot longer.



I'll try switching up battery brands. The out of the box cells from Ikea were dead in weeks, the store brand ones at least gave me a few months.


Battery brands (or even skus in the brands) can matter a _lot_.

Related, Panasonic's rechargable eneloop have worked very well for me, I'm kind of excited to see AAA be used in the IOT devices where it can fit.

I have a lot less of a problem swapping batteries if I just have a few charged ones on hand and get at least many months in-between replacements.


Top tip: IKEA rechargeable batteries are probably rebadged Eneloop Pros.

Just a heads up: IKEA's brand of rechargables are likely rebadged eneloops at about half the price, also made in japan. Though for the AAA's they only have eneloop regular equivalents not eneloop pros.
