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.
These batteries can work well in Blink cameras and can last longer than disposable Energizers in some setups.
The included holder can function as the charger, which makes charging simpler and more convenient.
These batteries can maintain near-alkaline 1.5V output longer than NiMH rechargeables, which helps power higher-voltage devices.
These batteries can deliver stable performance in Kwikset electronic door deadbolts without battery-type error messages.
The charger and battery chemistry can be safety-sensitive, and using the wrong charger type or fast charging can create overheating or fire-risk concerns.
The batteries can cut off instantly when depleted, which can prevent low-battery warnings in devices that estimate remaining capacity from voltage.
Charging behavior can be slow or inconsistent when using insufficient USB-C power, which may leave batteries blinking for a long time.
Some batteries may fail to charge or show blinking patterns that return to "full" quickly, which can indicate a dud cell.

update: they finally all stop blinking. but man that's a full day of charging almost
In contrast, our daily rechargeable Ni-MH batteries generally keeps about a 1.2V max and drops off quicker then these. So these are better but be aware they aren't your daily rechargeable battery.
for most devices, this is fine. If they take 2 AAs, they are designed to work with only 2.4v even though they get 3v with fresh batteries. but some devices are very picky.
for example, i had a logitech mouse that took AAs and my eneloops would die in 2-3 days. but it'd last 3-4 weeks with plain ol' duracells. it's because NiMH only provide 1.2v at full charge. these lithium batteries actually deliver the full 1.5v so if you have power hungry devices that require the full voltage, these will work while eneloops won't.
if you read the instructional manual, many devices will warn you not to use nimh batteries because they are undervoltage.

it is gonna take longer but better for the battery

they specifically recommend a "5V3A power supply" so you want a charger that provides a minimum of 15 watts
