I think it is more about the power required to run the lock motor.
I have several z-wave door locks as well. They all need battery replacement within a few months. Unless I don’t open/close them very often. They can go much longer.
But it really isn’t to big of a deal. Home Assistant tells me when they are getting low and I just swap the batteries in a few minutes.

The motor runs only for a second or two each time. In the moment, it takes more current, but otherwise isn’t that active.
If I had to change the batteries once or twice a year, I could probably live with that. But every month or so? Bad engineering
