These 1.5V lithium AA rechargeables stand out for devices that want alkaline-like voltage, especially Xbox controllers, Blink cameras, smart locks, and other power-hungry gear. The included holder doubles as the charger, which makes charging simpler, and the batteries are reported to hold 1.5V longer than NiMH cells. Runtime can be strong, with some setups lasting weeks or months. The main cautions are sudden drop-off with little warning, compatibility limits with the charger and chemistry, and occasional dead or failing cells. A practical option if you need full-voltage AAs and can handle the charging quirks.

Almost no one measures it since it takes a good while to do. Here is a German site (need Google translate) that did. Notice that EBL is bottom of the pile for capacity and % retention, but people like them anyway. Xtar is top, but very expensive.

Note - Since they put out 1.5v continuously they could be 95% discharged and you CAN'T TELL with a voltage check. Another 'problem'. with these batteries.

I've rotated this one AA battery into the other smart lock and it'll do the same thing.
It's not big deal. Replacement is arriving today and the 7 other batteries have all stayed steady over 1.5V since installing.
