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.

Common Questions (5)

  • Reported runtime varies by device, from weeks in controllers to months in smart locks and several months in a Flume leak detector. They also maintain 1.5V longer than NiMH cells, but some users report steep drop-off at the end and occasional failures after a few cycles.

  • They work in Blink cameras, Xbox controllers, and smart locks, and the 1.5V output helps devices that prefer alkaline-like voltage. In smart locks and controllers they can last longer than NiMH cells, but they may shut off suddenly and some devices lose low-battery warnings.

  • The case is meant to be charged with a 5V/3A USB-C power supply, and a lower-amp charger will still work but can take all day. A charger with more than 3A is fine as long as the voltage matches, because the device draws only what it needs.

  • No. These are lithium-ion AA cells with built-in electronics, so they need a charger designed for 1.5V lithium batteries; charging them in a NiMH charger can damage the cells and create a fire risk.

  • Yes. The set includes a holder that also functions as the charger, so the batteries charge in the case instead of needing a separate charger. That makes it easier to store and recharge the pack together.

Be aware that Lithium uses different chargers and handle a little differently then your regular Li-ion batteries.

what's nice here is that it comes with the holder that's also the charger. makes it easier for all.

Proprietary charger fails your screwed.

I bought these July 2025 for $13 and they are still going strong. I have another similar style and haven't tried to cross the batteries/chargers, but this one definitely lasts longer than the other. I just use these for blink cameras and charge them at 5V-1A (pretty sure that is what the manual called for and made me question the charge rate claim) while I think the other called for 3A, all my generic batteries I'd rather do at 1A while I'm at home and aware of it charging just in case

I used these in my kwikset electronic door deadbolt and the batteries last much much longer. No error messages about battery type. Full power all the time and so far lasting 2x as long as regular batteries.

You can charge them in a proper smart multi charger that supports 1.5v Lithium batteries.

these are entirely li-ion batteries with a step down voltage board attached.

They work very close to the alkaline AA batteries. The lithium keeps the 1.5v at a higher rate before dropping off at the end. So the advantage of this is to power devices that uses high voltage.

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.

The battery gets hot during charging; how can it dissipate heat with such a tight enclosure?

I use these in my easy to reach blink cameras. They work, but not as long as disposable energizers, so cameras in hard to reach areas still get those.
