I'm finding it really tough to justify 3x the NiMH price, especially when about the only devices I can think of that seem extra sensitive to lower voltage are smoke detectors and these always tell you specifically don't use them in items like that. I have some other sensor type devices (ecobee + myQ) that get annoying at lower voltages but they're a button cell battery format. Most things also say don't bother using them in low drain devices like remotes due to the parasitic drain from the buck converter.
We have game controller like for the Meta Quest, these don't seem to have problems with the NiMH from my perspective (but kids are the ones using them 99% of the time), anyone seeing an actual difference in this use case? We have plenty of xmas decorations that use AA, twinkle lights, led lit wreathes, etc... These seem OK with NiMH - same question as before.
