Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.
Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.
This is a garage-door so its not critical access but is used a lot.
It’s not a deadbolt (they have some), but we found a Schlage we liked. I can’t find it on the site, but search for electronic not smart. It might have been Home Depot.
It was easy to install and the battery hasn’t run out after over a year. I’ve used the key maybe once.
