Yeah, I’ve seen those (though not with the built-in charging; that’s cool). Even had some Ni-Cd ones back in the 90s. The only issue I have with using those in things like smoke detectors is having to deal with them more often. I can usually get about 18-20 months out of an alkaline but a Ni-MH one would probably be only like 8 months since the voltage and capacity are both lower.
Well, scratch that. I just found what I think you’re talking about, and those are 1300 mAh lithium. Those should last longer than an alkaline. Will keep those in mind next time I replace the smoke alarm batteries.
