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.
Blink camera owners, because these lithium AAs can run those cameras for long stretches and match the higher-voltage requirement.
Homeowners with smart locks, because they run longer than standard rechargeables and keep full power in voltage-sensitive locks.
Gamers using Xbox controllers, because they hold 1.5V longer and can last weeks of play without the voltage drop seen in NiMH cells.
Parents powering kids' toys, because the batteries are useful for devices that burn through AA cells quickly.
People who need a low-battery warning before shutdown, because these cells can drop from full voltage to dead with almost no warning.
Shoppers expecting universal charger compatibility, because these batteries need a charger made for this lithium chemistry and can be unsafe in the wrong one.
Devices that sit unused for long periods, because self-discharge and sudden cutoff can leave them empty when you need them.
Fast-charging setups, because the charging box can overheat or melt when fed too much power.

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.
