These 1.5V rechargeable lithium AA batteries are best for devices that want alkaline-like voltage, especially Xbox controllers, Blink cameras, smart locks, and other higher-draw gear. The built-in holder doubles as the charger, which makes the set convenient, and several reports say runtime is strong, with some devices lasting weeks or months and holding 1.5V better than NiMH cells. The main cautions are the sudden drop-off at end of charge, limited warning before shutdown, and the need for the right lithium-compatible charger and charging habits. A few packs also arrived dead or failed after a short time.
People running Blink cameras, because the batteries can deliver long runtime in camera use and suit devices that need 1.5V lithium cells.
Gamers using Xbox controllers, because they hold 1.5V longer and can last weeks of play without the voltage sag common in NiMH cells.
Homeowners with smart locks or door deadbolts, because the batteries keep full power longer and can avoid low-voltage error messages.
Parents powering kids' toys, because the batteries are useful when AA cells get used up quickly.
People who need a low-battery warning before shutdown, because these batteries can drop from full voltage to dead with little notice.
Users of devices that sit unused for long stretches, because self-discharge and storage behavior can be variable and the cells may go dormant or lose charge.
Shoppers expecting trouble-free charging with any USB source, because the case can charge slowly on low-power adapters and can overheat with a fast charger.
People using a smart lock with a tight battery compartment, because at least one AA can read 0V, charge briefly, and then fail again after a few uses.

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.
