2,400mAh of constant-voltage lithium power, four batteries charged at once, and 500+ cycles in a reusable pack.
Ordinary rechargeable AAs are Ni-MH, which sit at 1.2V and sag further as they drain. Devices dim, motors slow, and a half-full battery can read as flat.
The NH2400 holds a constant 1.5V and its voltage drops smoothly and gently right to the end. Your flash keeps firing at full power, your toy keeps its speed, and your light stays bright until the cell is truly empty.
Each cell charges through its own USB-C port, and the included 4-split cable tops up all four at the same time from a single source in around 3 hours. The cable carries a USB-A and USB-C end, so it plugs into a wall brick, a laptop or a power bank.
A small indicator glows red while charging and green when done, so there is no separate charger to buy, store or remember.
Each NH2400 recharges over 500 times, so a single cell does the work of more than 500 single-use alkaline AAs over its life. That is a lot of batteries kept out of the bin and out of your shopping list.
It is mercury, lead and cadmium free, and globally certified, so the saving is good for the drawer and for the planet.
Ni-MH rechargeables run at 1.2V and fade. The NH2400 holds a full 1.5V, so high-drain gear like camera flashes and toys runs the way it should.
USB-C charging is built into each cell. Charge four at once from any USB port. A separate dock or charging bay is one more thing you do not need.
500+ cycles per cell replaces hundreds of disposables. The pack pays for itself, then keeps saving for years.
Standard AA size and shape. Use it in remotes, cameras, controllers, clocks, toys and lights, exactly where a normal AA goes.
Remotes, wall clocks, smart door locks, game controllers, camera flashes, ear thermometers, kids' toys, camping lanterns and basic flashlights all run on the NH2400.
Keep the four-pack charged in its case and you have a ready set of full-voltage AAs for the whole house, instead of a junk drawer of half-dead disposables.
Remotes, clocks, door locks and toys that you would rather recharge than keep buying batteries for.
Flashes and strobes that need a true 1.5V for fast recycle times, where Ni-MH falls short.
Controllers and gamepads that stay at full output through a long session, recharged by morning.
Headlamps, lanterns and GPS units kept topped up from a power bank, far from a wall socket.

Yes. It is a standard AA size and shape and delivers 1.5V, so it drops into anything that takes an AA. Always replace all the batteries in a device together, and do not mix it with other types or brands in the same device.
No. Each cell charges over its own USB-C port using the included 4-split cable, from any USB-A or USB-C source. There is no charging dock or bay to buy. The battery charges only through the USB-C port, not inside a device.
Standard rechargeables are Ni-MH at 1.2V, which sag under load and need an external charger. The NH2400 holds a constant 1.5V for full performance in high-drain gear and charges four at once over USB-C, so it is both stronger and simpler to live with.

very happy with the purchase. bought it for a device and previously, the batteries given by the merchant can only run approx. an hour and takes nearly a day to charge. with nitecore, it took less than 2hr and can run double the time. have recommended nitecore to my friends as well. advice given via whatsapp are prompt and useful as well, when i needed to know which battery to get.
Great product. Love it

Now it's time to review after 1 month of usage with highest setting on my doorbell. Most of the famous brand batteries out there couldn't even last a week with highest setting like lingering detection with immediate recording, face detection and even get better network connection with this NITECORE AA BATTERIES. Simple to use and convenient as USB C port built in, just connect with the cable provided and plug in to charger wether with USB A or USB C slot. Thank you NITECORE with this so powerful batteries so I don't waste my money for keep on buying batteries that not convenient and it's good for environment too. WELL DONE 👍👍👍👍
Never thought this could replace current traditional AA batteries. Its a simple but innovative creation. Useful since can save cost on AA batteries.
Looks solidly built. The included cable makes charging easy
Looking forward to try nutecore batteries. They are not the usual 18650 abatt. Got it for my high drain torchlight
This is my 4th set (4x4) of purchased. I like the 1.5V with 2,400mAh rating. I Wil replace all my 1.2V rechargeable batteries in due course.
Battery is easy to use and charge. order came really fast so kudos to the team for the efficiency
The most practical solution to rechargeable batteries. Well thought out in designing a 4 way cable and the storage pod helps transport the batteries safely. Looking forward to a 18650 version in future
Nitecore AA rechargeables is doing great to pump out 1.5v compared to traditional NiMH 1.2v. Love it!
Charging speed:Very fast Battery capacity:Very good Items received in good working condition. Delivery was fast. My 2nd and 3rd set of batteries.
Overall good to use. It will be good if nitecore can lower the pricing another good $20 to encourage more users. Ultimately pricing is something users will consider for the first buy follow up with the second or third purchase.
Good any easy to use. With the long life cycle it can save lots of money. Got it at very good price for 8 pcs.
Great Product will not ever need to buy batteries for my Blood Pressure Machine Again.
All charged and ready! This is next level stuffs! 💪🏼💪🏼
Most AA rechargeable batteries are rated at 1.2v. Been waiting for 1.5v rechargeable batteries. Nitecore haven't disappoint me yet. Will use these to power my digital gate lock. Hope it works. Will save a lot of cash. Thanks.
convenient to do charging, no need bulky charger.
was looking for rechargeable batteies for home use and came across nitecore with usb cable charging. doesn't require a standalone charger? let's try it out & the stable voltage is a bonus
So far this is the only 1.5V rechargeable battery on the market.
They have became part of my battery stock, ready for different uses at home.
Very convenient and compact to carry around.
Such quality AA is finally here, with indicator lights for safe charging, and if you would also make them in AAA.
i bought the AA size rechargeable batteries to use them on my portable radio which i use locally and overseas. The batteries are able to last for 24hrs continuous running for 2.5 days.
good product and compact
Great packaging Easy and powerful battery Most importantly rechargeable
I would go through 4 sets of alkaline batteries every 3 weeks, which is both expensive and not eco-friendly. Changing to the NH2400(AA) is certainly going to be eco-friendly and hopefully economical as well...
At last AA size 1.5V rechargeable batteries from nitecore 😻
When I saw this awesome product launches, immediately grab 2 sets instead of one! Really respect the idea of environment care, useful and waste less !
