The new/2018 SmartThings motion sensor works well for me, and I only recall replacing the battery in mine once since I got it shortly after its release (though I'd say the same for every generation I've owned--v1, v3, and v5; one gen I don't own had mixed reviews, and maybe you have one of those). Otherwise, since you're using Z-Wave, I assume you don't mind slightly slower motion sensors I wouldn't otherwise recommend. :) There, the Zooz ZSE18 and HomeSeer HS-MS100+ G2 have similarly long battery life for me, and both have the option for USB power if you can and would prefer that (as does the new Inovelli 4-in-1, which I hasn't been out long enough to judge battery life on yet, and the Aeon Multi 6, which is probably the only way I'd use that since mine *does* eat batteries). People also seem to like the newer Ecolink as suggested above.
