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.

    Yeah, it’s because of the buck circuit regulating them down to 1.5v. No warning, they just die because the safety cutoff turns off the circuit when the lithium voltage drops too much. I can live with it though.
