I've switched to rechargables for home electronics years ago. It makes me feel better doing my share of lessening environment impact caused by disposable cells.

One notable exception for which I am still buying alkaine batteries is the August Smart Lock. When using NiMH batteries it starts complaining about depleted battery in a week, while it still Ok and works for much longer. It was reported to them and they advised to us alkaine. This is very annoying because all they need to do is to fix the software which does the voltage check and generates annoying notifications to the users. Just a few lines of code (or maybe single constant) could have an immence environment impact.
