The Amazon Basics 8-Pack Rechargeable AA NiMH Batteries have been a fantastic addition to my household. I’ve swapped out most of my regular disposable batteries for these, and I couldn’t be happier. They charge quickly and hold a charge for a surprisingly long time, making them perfect for everything from remote controls to toys and even my camera.The fact that they’re rechargeable is a huge bonus, both for the environment and my wallet. I’ve used them several times already without noticing any drop in performance, and they’ve been holding up well after multiple charging cycles.For anyone looking for affordable, reliable rechargeable batteries, this pack is a great value. They’re high-capacity, work well in a variety of devices, and help reduce waste, making them an easy choice for everyday use.

As a professional reviewer, I've had the opportunity to put the Amazon Basics 16-Pack Rechargeable AA NiMH High-Capacity Batteries (2400 mAh) through their paces. My findings are based on rigorous testing and comparison with other brands in the market.Upon unboxing, my initial impression was that these batteries are strikingly similar to the Sanyo eneloop XX batteries, both in appearance and specifications. This led me to believe that they might be rebranded versions of the same. To confirm my suspicion, I embarked on a series of tests using my La Crosse BC1000 Battery Charger/Analyzer.Here's what I found:Pros:+ High Capacity: The batteries delivered an average capacity of 2555mAh after a few recharge/discharge cycles, exceeding the rated 2400mAh. This is a testament to their high-quality performance.+ Quality Control: The tight spread between 2510 and 2610mAh across the batteries indicates excellent quality control.+ Value for Money: At the time of writing, an 8-pack of Amazon High-Capacity AA batteries costs less than a 4-pack of eneloop XX batteries, making them a great bargain.+ Long-Term Performance: After 5 months in storage, the batteries retained 85% of their original capacity, outperforming the Sanyo XX batteries in my previous tests.Cons:- Size: These batteries are slightly fatter than typical AA batteries, which might cause fitting issues in devices with extremely tight battery compartments.- Lifespan: While they perform excellently in the short term, these batteries seem to lose their ability to hold charge after a few years. If you're a heavy user, be prepared to replace them after 2-3 years.- Country of Origin: Some users have reported a drop in quality in batteries made in China compared to those made in Japan.In conclusion, the Amazon Basics 16-Pack Rechargeable AA NiMH High-Capacity Batteries (2400 mAh) offer excellent performance and value for money. However, their slightly larger size and shorter lifespan compared to other brands might be a deal-breaker for some users.Remember, the best battery for you depends on your specific needs and the devices you intend to use them in. Always consider these factors when making your purchase decision.

Rechargeable batteries are a must in our household with 5 kids. We go through AAs quickly between remotes, toys, flashlights, game controllers, and more. Switching to rechargeables has saved a lot of money over time, and these Amazon Basics 2400 mAh NiMH batteries have been a solid choice.The 16-pack is a great value, and the 2400 mAh capacity is above average for NiMH AA batteries. Low self-discharge is an important feature — they hold their charge well when sitting in storage or in devices that aren't used daily. No memory effect issues either.I've been using these alongside a compatible charger and they've cycled through many charges without noticeable degradation. Great value for anyone looking to reduce battery waste and save money in the long run.

What I likeThe price is real. Amazon Basics NiMH is cheaper per cell than the Eneloop 12-pack, and noticeably cheaper than the Energizer 16-pack. If price is the deciding factor, these are the cheapest option I have used.They work. The batteries power controllers, lights, and small devices without failure. They hold a charge long enough to be useful day-to-day.They are pre-charged. I can pull them out of the pack and use them. The pre-charged rating matches what I have experienced.I still use them. Three years in, I have not thrown any out. The green batteries are still in rotation.What annoys meThe 2400 mAh claim does not survive a refresh. Real refreshed capacity is below 2000 mAh on my tester. That is the headline gap between the marketing label and the lived experience.They are physically bigger than other AAs. The size difference is enough to cause fit problems in tight battery compartments on at least one device I own.They do not hold a charge as long as Eneloops on the shelf. Between refresh cycles, the Eneloops stay useful longer in low-drain devices. The Amazon Basics lose meaningful charge faster.The price gap is shrinking. I keep buying the Eneloop anyway because the per-cell cost difference is no longer large enough to justify the fit and capacity problems.Capacity is not the only number that matters. Even if the cells delivered close to 2400 mAh on day one, that does not help if the device fits them poorly or if they self-discharge faster.Who it is for, and who should skip itIf the deciding factor is price per cell and you only need AA batteries for low-drain devices that do not mind a slightly larger cell, these will work. For someone outfitting a garage full of remote-controlled toys or stocking a drawer for occasional flashlights, the Amazon Basics 2400 mAh pack is acceptable.Skip them if the device has a tight battery compartment, if you want honest 2400 mAh, if you need long shelf retention between uses, or if the price gap between these and the Eneloops is small at the time you are shopping. I am in that last group now, and that is why these are my least favorite.VerdictThe Amazon Basics rechargeable AAs are cheaper than my Eneloops, work well enough to keep using, but do not deliver on the 2400 mAh label and run physically large. They are a price choice, not a quality choice.Grade: C. Buy them only if price is the deciding factor.

Amazon Basics AA Rechargeable Batteries (2400 mAh) – Real Capacity Test ResultsI ran a full analysis cycle on 8 cells using an ISDT N8-series smart charger at a 0.5A charge/discharge rate. Unfortunately 4 of the 12 cells were accidentally thrown out with the broken toy they were in so I couldn’t test those. Here are the actual measured results after initial break-in and a few months of normal use in kids toys and various gadgets:Capacity Results (mAh):- 3001- 2687- 3001- 2658- 2639- 2625- 2649- 2698Average Capacity: 2700 mAhRated Capacity: 2400 mAhInternal Resistance (mΩ):- Range: 124 mΩ – 200 mΩKey Takeaways:• All 8 cells tested at or above their rated 2400 mAh capacity• Two cells measured around 3000 mAh, which is significantly above spec (likely inflated slightly by the lower 0.5A test rate, but still impressive)• Most cells clustered tightly between 2625–2700 mAh, showing good consistency• Internal resistance varied from 124–200 mΩ, which is decent but not premium-tier lowWhat this means for real-world use:These are solid mid-to-high performance NiMH cells:- Great for moderate to high-drain devices (controllers, cameras, etc.)- Not quite as consistent as premium Japanese made brands, but very close considering the price- One higher-resistance cell (~200 mΩ) may perform slightly worse under heavy load and prematurely wear out. Lower resistance means less voltage sag under heavy load.Pros:- Exceeds rated capacity across the board- Good consistency between most cells- Good value for the priceCons:- Internal resistance spread is noticeable- Not all cells are perfectly matched for High-drain useFinal Verdict: 4.5 / 5 (Rated five stars because you can’t give a half star rating, close enough however):For the price, these perform above expectations. If you’re willing to match cells based on performance (capacity + internal resistance), you can get excellent results comparable to more expensive brands.Testing Note:Results were obtained using a 0.5A analysis cycle, which can slightly inflate capacity readings compared to higher-drain real-world use. Not an appreciable difference however in actual usage.Testing Equipment - ISDT N8 Series Smart ChargerPlease note: Don’t be disappointed if brand new cells don’t meet their rated capacity out of the box. NimH rechargeable batteries have a break-in period when new. This is usually 3-5 full charge/discharge cycles (for premium Japanese-made cells around 2 charge/discharge cycles). A good smart charger can do this for you. It can take several hours or they will break-in themselves over time with normal usage but their performance will increase after break-in.

I use a lot of battery operated LED lights throughout my house. Very difficult to run AC through the walls. (Cost). I've had rechargeable batteries for years and they have come in handy when power goes out. I have lights also in my closets. I haven't had to change them out in about 6 months. These rechargeable batteries do very well in your game controllers as well. I use these in my FLIR for work and they perform great. Also use them in my multimeters with no problems. All my remotes have either AAA, or double AA batteries. It's been years since I have bought a alkaline battery.It's very economical to use rechargeable batteries! I keep at least 45 AA's charged at all times. Rechargeables perform very well under load, and stored. It does advertise that they come charged, but they are not 100% charged. There is a reason why they do come with a charge!? If they had no charge, you could not recharge them, because your battery charger would not recognize them. You would just get a blinking light. You would have to jump start each one... (Check out YouTube for rebooting your dead batterys) do not throw them away, they still have life. The only negative thing I have to say about these rechargeable batteries that save's you money is... The climate crises zealots 👣... These people need to grow up! It's really a political statement. I just want to buy, or say something without it being politicized!? I highly recommend using rechargeable batteries. It is Earth friendlier, as well as cost-effective. We really don't need a stamp of approval to think that way... Do we?

I am a flashaholic! That is a name that we flashlight nuts call ourselves at a blog we all meet at to discuss the various flashlights we own, what's new, and answer each other's questions when we can. I won't name it here, but search for 'flashaholic' and I'm sure you will find it. I own a couple of very high power flashlights, and a very nice bright lantern for emergency use like power outages. Now, one thing all flashlights do is eat batteries like they are going out of style. Now using alkaline AAs wasn't too bad, since I can get them at our favorite on-line store for about a quarter a piece, but I still found myself restricting use of the two that used them in an effort to save money. But my super high power light was another matter. Replacing eight cells at a time at $2.00 each gets expensive. So when I found myself with a few extra dollars and a great deal on a charger and rechargeable cells at you know where, I jumped at it. But that left the AA lights. Buying eight higher capacity rechargeable AA cells was going to cost around $40.00 USD. But then I ran across these cells here at our favorite store for half that price. Yup, you guessed it - I bought them. And they have been great! I have always had good luck buying Amazon Basics, and this is no exception. They charged up nicely, and work well in my lights. Others will tell you that you should save your money and buy the lower capacity Eneloop-style cells that can be recharged 2,000 times, as opposed to these that can be recharged only 500 times. Well, I got these Amazon Basics for LESS than the price of a similar set of the lower capacity, longer lifetime cells, and less than HALF the price of the equivalent high capacity cells. I figure if I recharge them once a month I will still be using these cells forty years from now, assuming I am still alive by then.Bottom line, if you are looking at rechargeable AA cells, these are the ones to get. Trust me, I work for the government! (I really don't, I just had to say that. My weird sense of humor, don'tcha know!)Edit [10/31/14]: I have now run these cells through several recharge cycles, and they are holding up as well as I expected. Before I got these cells I was using lithium AAs in my one high power flashlight, and these cells are doing just as well as their replacement. The old wisdom is that rechargeable cells don't last as long as alkalines, but make up for it by being rechargeable. Well, that doesn't hold true here. These cells are lasting as long as the lithiums did, and charging right back up ready to do it again. I plan on buying another set as soon as I free up some disposable income. You can't go wrong with these cells and a good charger.Edit 4/5/15: I sat down with by battery log and my calculator the other day, and figured out that I have recharged enough cells to pay for the charger, the original 18650 cells, and the AA rechargeables. From here on in, all my usage is free. It is a great feeling, and these AA cells really helped me get there

I measured mAH capacity on an accurate tester, sampling 4 batteries out of the 24 I ordered and all four met the spec. Pretty impressive. What I don’t know yet is what the self discharge curve looks like, but I’ll find out over the next year. I doubt if it’s as good as Panasonic Eneloops, but hoping. Good value.

The battery seems okay, but the size for this AA battery, not sure had it got 1mm extra bulk, it seems to not fit normal UM-3 slot. I had to massage it in. Will see.

Bought these for a video game my son has, they work well and last decently long, not as long as top brand lithium non rechargeable batteries but at least we can recharge these . They are made from NIMH, imo its an outdated technology, should have lithium ion batteries but i guess the price would be higher. I recommend.

子供の動くおもちゃやゲームのコントローラーで単3電池の消費が激しく、毎回使い捨てのアルカリ電池を買って捨てるのがもったいないと感じて、こちらの12本セットを購入しました。結果的に、もっと早く買えばよかったと思うくらい大活躍しています！一番のメリットは「2400mAhという大容量」です。一般的な充電池よりも容量が多いため、一度フル充電すると消費電力の大きい機器でも体感としてかなり長持ちします。しょっちゅう電池交換をするストレスが激減しました。また、12本も入っているので、使っている間に別の電池を充電しておく…というローテーションが余裕で組めるのも便利です。購入して届いた時点で既に充電済みだったため、開けてすぐにおもちゃに入れられたのも地味に助かりました。1年放置しても50%の容量を維持してくれるそうなので、防災用・備蓄用としても安心です。ただ、使ってみて事前に知っておくべき注意点もいくつかあります。まず、高容量のニッケル水素電池の宿命なのか、普通のアルカリ電池と比べて「本体がほんの少しだけ太い」です。機器によっては電池ボックスに入れる時に少し窮屈に感じるかもしれません。また、繰り返し回数が「最大400回」と他社製品より少なめですが、1回の持ちが長いことと、この大容量が12本パックで手に入るコスパを考えれば、個人的には全く問題ない範囲です。使い捨て電池のゴミ捨てや買い出しの手間から解放されたい方、ハイパワーなガジェットをたくさん持っている方には、間違いなくおすすめできる商品です！（※充電器は必ずニッケル水素電池専用のものを使いましょう！）

I was going through batteries like water for kids toys. These have been great in both AA and AAA. Very easily charged and good life on them once charged. It has saved me a lot compared to constantly buying batteries.
