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).

Community Reviews

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.

Common Questions (5)

  • They can last much longer than NiMH cells in higher-voltage devices, with reports of weeks to months of use in Xbox controllers and smart locks, and several months in a Flume leak detector. In Blink cameras, they work well for some setups but may still last less than disposable Energizers in harder-to-reach cameras.

    mkdenarmattnis1BigburitoJedi2155

  • Yes, the case is meant to be powered by USB-C and the listing calls for a 5V/3A supply. A lower-amp charger will still work but can take all day, while a charger above 3A is generally fine because the device only draws what it needs.

    HopP61633erishunerishunerishun

  • Yes. They hold a steady 1.5V until the internal cell is depleted, then can shut off abruptly, so devices may give little or no low-battery warning. That makes them great for devices that want full voltage, but less predictable for gear that depends on gradual voltage decline.

    LovelyGoat9932Jedi2155mllkAmusedFruit500

  • No. They need a charger designed for 1.5V lithium cells, and using a NiMH charger can overcharge the wrong chemistry and create a fire risk. A proper smart charger or the included charging case is the safe option.

    FeistyWeather4142VioletFruit436CleoThymeTheAbominableSquash

  • A test with an XTAR VX2 Pro measured about 2000-2100 mAh, or roughly 2800-2900 mWh, at a 300mA discharge rate. That is below the headline 3000mWh claim, but still enough to outperform many NiMH AAs in devices that need a full 1.5V output.

in which way? why cant u put into a normal charger? or charge other AA batteries in it?
Lithium cells require a specific charger, hence the previous comment. These cells are made with a specific charging map in mind, so generic devices will probably be less effective/ detrimental to the lifespan of the cells.

I use this in my Flume water leak detector... 4 go in the detector while the other 4 recharge and are ready.... They last several months.
How they have those proprietary packs?

I got these, one of the batteries was bad, customer service responded in a day and had me buy 2 more batteries then refunded me. Based on that customer service alone I'd keep buying these. Not to mention they last longer than any of the USBC li-ion batteries I've bought. 5 stars!!!

u mean customer service through amazon?

buy 2 more and then u wait for them to have to refund u?

what happens if they bounce from amazon and respawn as another selller.

Quote from LovelyGoat9932 View quoted comment :
I have a different brand of these sorts of batteries (both AA and AAA from a previous deal) that have USBC charging connectors on the battery itself, and was surprised at how suddenly they fall off the cliff - like 1.5 volts to zero volts in seconds when they need recharging. Just be aware that they can run out of juice instantaneously. I use mine for mouse and keyboard, and one second everything works, and then nothing does. I don't think it's a fault, just something to keep in mind.
This is by design. With other batteries like alkaline and NiMH, the voltage goes down slowly as use use them. At some point, you reach a cutoff where it will not power the device, even though the battery itself has some juice left it in. Another issue is that some devices actually require voltages closer to 1.5V to function properly. These batteries were created to solve these issues – they have a voltage regulator inside them so that they can output 1.5V even when the battery itself may be depleted to below where a NiMH or alkaline battery would cut off. As a result, they can squeeze every last drop of usable power out of it. A side effect of this is that the voltage regulator will keep putting out 1.5V until it can't anymore, which means that it will just cut off instantly when the battery is out of juice. Most devices use voltage to estimate capacity, and since they will always see 1.5V due to the regulator, the device will not have an idea of what the remaining capacity in the battery is.

Suggest me with ones with the best capacity.
The ones with the highest mWh have the highest capacity (i.e. the most amount of energy that can be stored in them). For non-lithium rechargeable cells, you can calculate the mWh by taking the mAh and multiplying by 1.2. So for a 1000mAh NiMH battery, for example, you would get 1200 mWh. Similarly for lithium. If you only know the mAh of the battery, for lithium you multiple by 3.7 to get the mWh. Whichever battery has the higher mWh has the highest capacity. (for non-rechargeable cells like alkaline, use 1.5 as the multiplier)

Every single rechargeable battery out there is labeled in mAh. Watt hours, even if it is more accurate, tells me nothing when shopping for batteries.
Lithium batteries are often labeled in mWh.

Be aware that Lithium uses different chargers and handle a little differently then your regular Li-ion batteries.
This _is_ a regular Lithium-Ion battery. Nothing special about it.

Unfortunately it looks like the code NVHHEPPK is no longer working.
