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.


I was super anti smart locks until I left my garage open and doors unlocked for an entire weekend because I’m forgetful. With smart doors and locks that doesn’t happen and, possibly a controversial take, doors being closed and locked by reputable smart devices is more secure than them standing open. Most crimes are those of opportunity, and a thief is just gonna try the door and break a window when it doesn’t open if they’re willing to go that far.
I came into this thread to scoff at the idea of needing batteries for a lock.
I’m coming round to the idea…
