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.

I pulled the trigger but then noticed the recent poor reviews, due to the fact they stopped working after only a few cycles. Not worth the hassle. Damn - was gonna use them for my Quest 3 controllers.

I should add to my prior comment: These are listed as mWh, not mAh (like most rechargeables), so it would be about 2000mAh (like most NiMh batteries).

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.

  • These batteries can maintain a higher 1.5V output longer than NiMH rechargeables, which helps power higher-voltage devices.

  • These batteries have worked well in Blink cameras and can be charged at 5V-1A per the manual, with runtime lasting longer than some other USB-C lithium AA options.

  • The set includes a holder that also functions as the charger, which makes charging more convenient.

  • These batteries have been reported to last about twice as long in a Kwikset electronic door deadbolt without battery-type error messages.

  • Some units have reportedly failed after only a few cycles or arrived dead on arrival, including cases where a battery would not charge or read 0V.

    SatchrianiLavenderSeagull366justinmonroe84

  • The batteries can drop from full voltage to shutoff without a low-battery warning, which can cause sudden device failure.

    amocadloAmusedFruit500

  • Charging behavior can be slow or inconsistent when using insufficient USB-C power, which can leave batteries blinking for an all-day charge.

    erishunlamah

  • The batteries can get hot during charging, which raises concerns about heat dissipation in the charger enclosure.

Quote from bmwe30nut View quoted comment :
I'm interested in how much self discharge they have? I get Low Self Discharge (LSD) NiMh batteries like Duraloops, etc. so they can sit. I'd get these easily if they can sit for extended periods before losing much charge.
The LSD properties are HIGHLY variable. Depends a LOT on the quality of the Lion cell and the electronics. As indicated, there is ALWAYS a lot draw, nature of the device.
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.

Be aware that Lithium uses different chargers and handle a little differently then your regular Li-ion batteries.
It seems there was a mistake in the title. They are lithium-ion, not lithium batteries

Same company makes the EBL lithium ion batteries, FWIW.

All of this kind of battery has a low voltage cut-off. They also have a slow steady discharge>All of them. So a sitting battery "might' seem to go dead in storage. It will go 'dormant' and CAN show zero volts. It could be fine and come awake/revive on the charger. That would be acceptable, but it does show they are older stock.
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.

Got a Philips Wi-Fi Smart Door Lock that eats AA batteries. Not sure why this door lock didn't come with rechargeable batteries. This seems like a good alternative to going thru batteries and tossing them out.

I'd put that battery back in the charger, it'd flash charging for about 30 seconds then say it's full again. I'd put it back into my smart lock, it'll work a few times, then a few hours later when I actually need to use it, its showing 0 volts again.

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.

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've tried a few different brands of rechargeable lithium batteries for my piece of crap blink system eneloop pro and they ALL suck. The only thing that works is energizers non rechargeables. I'm going to trash these cameras and set up. I have them on barely sensitivity. They have alway been worthless. I've finally come to terms the system just sucks. The one thing I liked was I didn't need a subscription. Every other detail has been totally awful. I would not recommend these to my father-in-law and he sucks too.
