I love the idea. The 1.5 volts for a rechargeable AA is also incredible. I'll use these batteries in the Nitecore flashlights and offcoarse in children's toys.
Im all for it! Will upgrade my hiking gear, more capacity, less weight - no extra charger. Definitely perfect sulution ! Thank You for that informative vid.
Finally a 1.5v rechargeable Lithium AA! Way to go Nitecore! I've previously attempted to switch to all rechargeables but I have several devices that won't even run on 1.2v... A/V remotes, Fluke meters, and even personal trimmers. My digital camera barely will either. It gives a constant low battery indication and goes through them in no time.
I’m an avid camper and hiker and it’s always great to have efficient rechargeable batteries are ready for all the devices that we may need especially at night
On a decent sale, for a 4-pack of the Nightcore, I can get the equivalent of 4-6 LADDA packs. But I'm sure there's a use case for them when you can't bring bulky chargers when mobile/outside vs. the LADDA
@@NightFoxXIII Cost v quality? I know where my investments are made. Just like the tyres of my motorcycle - cost is immaterial, performance is paramount!
@@apistosig4173 Again, I can still see a use case for certain equipment like say the camera gear he's been saying but for everyday usage you don't really need it. This is more akin to like using regular or premium fuel (regular rechargable batteries vs. nitecore) in your car (electronic devices). Some don't care and take regular batteries fine. Others need that premium battery to perform its best. The comparisons made (if any) were random cheapo batteries on Amazon and even more bottom of the barrel. If there was comparisons to say other name brands or popular ones (ex. energizer rechargeable types, enerloop or even ikea branded ones), I'd think it'd be a more fair comparison to see.
Amazing batteries! I'm still using devices that require AA's and AAA's such as my multimeter, laser level and safe. Can't wait to get a set! Thanks MJ-Nightwalker Gear!
Yeah, I'm going to use on our RN-Registered Nurse front window light sign on our cars just like during the COVID pandemic. My wife and I are always called to hospitals, so we're easily spotted in police check points. We will use it to save lives of others.
Thanks for the coupon code! Was just looking into getting a set of batteries from a reputable manufacturer. Shipping was insanely fast! Received in a couple of days, charged up and doing endurance testing now. It's already proven to be better than off-brand usb-rechargeable batteries from the first use.
I would definitely use them, in the long term they will save a fortune, I also love that I won't need a clumsy battery charger. I've just bought myself and my two son's nitecore mt1A pro flash lights on your recommendations , they will come in very handy. Love the quick charge too. Can't wait to get my hands on them. 😁
Definitely a must for my digital lock, kids toy, and night light. These requires constant energy. Fast charge allows me to minimise the downtime of my devices
Following extensive review analysis, I recently purchased the MT1C PRO and MT2A PRO, two weeks ago. I also proactively acquired four batteries prior to your video release, having seen the thumbnail. 😅 Thank you.
Will be purchasing these when available. I have sooo many AA uses that these can replace. Appreciate your time putting this together and letting us know about this exciting new product!
The constant voltage is amazing and the built in usb c charge will definitely be a lifesaver and removes any battery anxiety for my on the go devices like mouse and camera!
Great video. Thanks for the info. My wife has numerous battery operated candles around the house. These are perfect to save alot of money instead of using alkaline batteries
These AA s look amazing and with the USB c connection is a game changer! I would love these for my RC Remote for my off road RC Buggy Great videos by the way have been watching your reviews for a while now and love your flash lights you have been showing lately happy new year Too.
These seem great for EDC kit with flashlight. I always forget to charge my flashlight battery but my kit has a powerbank. So at least I can have light in case of emergency.
Unless the keyboard uses LED backlighting, it's crazy to put these obscenely expensive things in there. A regular non-LED keyboard will last months or years with a set of cheap alkaline or Ni-MH rechargeable cells. These lithium based AA rechargeables have been around a good few years, but their main selling point (constant 1.5V) is a niche that most devices don't care about - and they are horridly expensive for what they are.
I would totally use the NH2400! To get more out of a battery and at the same time produce less e-waste. Such a convenient battery with multiple ways to charge it. I have the MT2A Pro, one of my flashlight i would use the NH2400 on, if possible.
As a ham radio operator - I would use something like this for backup power purposes in my handheld radios along with a AA case, when I need to listen (receive only) when primary battery packs are dead. I'd use these everywhere else as well... remote controls, AA flashlights etc. where I am currently using traditional AA rechargeable batteries.
for emergency bug out / shelter in place situations these batts would be fantastic .. actual capacity means lighter backpack as well .. pack 4pcs into the bag instead of 12pcs ..
I keep 3 AA flashlights in different kits. Exactly for the fact I can easily find AA batteries. I also use the LADDA batteries and yes, they take a while to charge. lol These are sweet!! Happy New Year! Cheers
I recently obtained the MT2A Pro as a birthday gift from my brother. I like it ever since watching your review and those new batteries would be a perfect fit for it since it also accepted 2 double A batteries
lovely! that’s the prefect backup solution for MT2A pro and also my blood pressure monitor (i have been look for trust worth 1.5v AA battery for long time, now that’s it!!) Time to replace my eneloop
I would use these in any of my electronics requiring AA batteries. As you mention they look perfect for trips and power outage situations. I generally use rechargeable batteries and avoid using alkaleaks. Another factor in cost savings would be less destroyed electronics by alkaleaks.
I've been using Ikea Ladda Batteries for years. Just the best value option available right now, and it's well covered that the Japanese manufactured variants are made in the same Enloop Factory.
You'll pay 4-5x the price for the same number of cells. Admittedly you won't have to also pay for a charger, but I'm still using my smart charger (for Ni-MH) and original Eneloops from 15 years ago. I doubt these lithium things will have the same longevity. If you have a use-case for the constant 1.5V then they're useful. Otherwise, Eneloops are still a great choice. Many devices simply don't need nor care about the lower voltage of Ni-MH.
oh these could readily replace all my batteries for my safe & digital measuring devices & laser, will definitely put them to good use, tonnes of usage. glad to get a hold on these rechargeable batteries!
These batteries come in handy when i do medical coverage, which i can used on my portable BP machine, ear thermometer. Especially like F1 events which last almost whole day.
My girlfriend loves Christmas decorations and the generic batteries form the supermarket die super quick. These would be so useful for next year 😅 She’d be the happiest girl on the planet to have Christmas decorations that shine all night
Many thanks for the new product info. I've been researching larger AA flashlights to replace my Bronte BR01. I would definitely put the NH2400 batteries to good use.
Interesting, hopefully they have enough current output for use in camera flashes. Should be a good replacement to Eneloops that I have been using so far.
I have found that the best upgrade is batteries with INCREASED VOLTAGE (1.6V) and INCREASED CAPACITY. Forget about these individually charged batteries! Who cares if you have to put them in a charger and wait for them to charge?! Most people have another set of batteries to use while 1st set are charging. Still very informative video. Giving options 👍 I watched more of the video. I commented too soon. I see these batteries hold 1.5V all the way through usage. 👍
I totally love this kind of battery. Standard USB-C is everywhere. I do not need to bring along a battery charger while travelling. This kind of battery is good for standard usage. It is also good for waterproof flashlight. It is like moving the charging port from the flashlight to the battery to achieve good waterproofing.
I will definitely use the Nitecore NH2400. I think it's perfect for an AA flashlight, though 18650 batteries can pack a bigger punch. Personally, I feel that AA is ideal for everyday carry. The fast charging and the use of USB-C is a game-changer. With USB-C so easily accessible, you can quickly charge the battery without needing a separate charger. If you're ever caught in a situation without spare NH2400s to swap out, alkaline batteries can also be easily found to power the device while the NH2400 is being charged.
Yes, I owned a lot of NiMH rechargeable batteries and it's too cumbersome to charge. I'll be using them for camera accessories, remotes and game controllers. Thanks.
Hi I love to have and use the Nitecore products, these are innovative and reliable for daily uses, I will use these AA batteries in Nitecore new MT1A Pro , MT2A Pro, MT21a, LA 10 and LA30.. Waiting for these new battries.
I would use this for my Speedlite(hotshoe flashgun for cameras). Currently im using Energizer rechargable batteries for it. Works fine overall but it takes waaaay too long to recharge and it gets alarmingly hot while charging. For Speedlites i hate using disposable batteries because they aren't reliable,usually about 10 flashes and they are drained out
How is the self discharge on this battery? If you leave it charged, will it discharge itself like a regular rechargeable or slowly discharge like an Eneloop
I'm curious how the run time would go with these on the AA lights. For example if you have 2 of them in the MT2A Pro, it's almost the same capacity as a 21700.
@bbsamu The lithium ion battery will have a higher output for sure, but 2 of these combined is 4800mah. So in theory could you get a very long (close to 21700) run time from 2 of these on lower lumen levels? I'm honestly not sure if there's any reason to use these in a light over the rechargeable battery it comes with.
@@Hunterssoldier 21700 cell has 5000mah x 3.7 v = 18.5 watt hours. 4800 mah x 1.5v = 7.2 watt hours. a 21700 has much more capacity than even two of the nitecore AA's with 2400 mah each.
I like them and yeah I'd use them and that cord is dope. I've never been a fan of the batteries with built in plugs due to capacity issues but these are very interesting.
You had me at “Constant 1.5V Output”. Many electronics simply perform better at 1.5V output. And at 2400mAh, it is an incentive to replace all of my AA size batteries!
Nitecore,"Constant" voltage, 1.5V, and USB-C are excelent for old headlamp and flashlight that cant use 14400 3.7V. They might be to thick for some, but would buy if sold here.
Yes will use Nitecore AA batteries NH 2400mah-1.5V in my digital door lock. Because it faster charging at 3hrs, capacity at 2400mah at 1.5 voltage, great value for the money will you no need to buy a lot of New AA batteries.
I think these have some great uses but if you are not using a smart charger to charge your batteries and maintain their health then won't they deteriorate through memory effect?
I use rechargeable nimh batteries in my rc car transmitters. They're ok but suffer from what you've mentioned. These batteries would be amazing to have!
Been running enloops for years thrilled to see another option that's easy to change in the field. Would love to run these in some of my older lights
Why not buy Ikea Ladda?? They’re the same as Eneloop for a fraction of the cost…They’re made in the same factory
@justkiddin1980 That's the reason I buy Ladda from Ikea too. 🙂
@ Yes they have been tested before and are indistinguishable from Eneloop..but yeah half the price
@@justkiddin1980
Ladda are only 1.2v not 1.5v like these are.
@@justkiddin1980 richtig! nutzte die auch bin sehr zufrieden! Laden auch extrem schnell und halten lange.
I love the idea. The 1.5 volts for a rechargeable AA is also incredible. I'll use these batteries in the Nitecore flashlights and offcoarse in children's toys.
I just ordered a drone to do videos for business. These batteries will make my pack complete. Glad I saw this video.

Very expensive compared to Ikea LADDA 2400 (rebadged eneloop), but the combo of 1.5v output and USB-C charging gives these a great niche use case.

When you use the 4-way USB-C adapter for four AAs, what is the total mAh can the charger theoretically provide? It is one amp for each AA?
