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.
don’t need to, I have it. it’s great. don’t need to carry keys around or fumble with them to open the door, people can get inside without me, it can be set up to auto-lock/unlock on a schedule if you want, and I never have to worry about being locked out of my house
