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 I’m a huge fan of the rechargeable lithium AAs but they do just die pretty much immediately since the power curve just falls off. But they last a long while and charge nicely.

        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.
