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.

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

For the most part these are good batteries. Of course the charge doesn't last as long as an alkaline battery, but that is fine since it can be recharged. The only issue I have is that they are slightly thicker and longer than a standard AA battery. They fit most things, but I have had to use regular alkaline batteries in about 25% of the devices I tried since these rechargeable batteries just would not fit at all.

I am comparing these to Energizer rechargeable batteries. The seem to charge as fast but they seem to last about half as long. It can be hard to do a direct comparison as no two devices ever seem to be used in the same way, but I tried these in some LED lanterns on a camping trip. The lanterns were the same make and model and were both brand new. One lantern had brand new, fully charged Energizers in it and the other had these Amazon Basics, also brand new and fully charged. (Both sets of batteries were charged on the same charger). I put the lanterns on a table and they ran continuously until the next day. The lantern with the Amazon Basics batteries shut off after about 16 hours whereas the Energizer batteries kept that lantern going for 28 hours. For the price, I think that these feel like a good value. Energizer is exceptionally proud of their products and charge accordingly. Yes, they may be better, but I don't think that they are the best value. It may turn out that the overal lifecycle of the Energizers is much better than the Amazon Basics, but the short-term results say that the Amazon Basics are perfectly acceptable. The green color is nice tool Other companies use green to indicate that their batteries are rechargable, so good on Amazon for leaning into that.

Amazon Basics AA Rechargeable Batteries (2400 mAh) – Real Capacity Test Results I 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 - 2698 Average Capacity: 2700 mAh Rated Capacity: 2400 mAh Internal Resistance (mΩ): - Range: 124 mΩ – 200 mΩ Key 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 low What 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 price Cons: - Internal resistance spread is noticeable - Not all cells are perfectly matched for High-drain use Final 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 Charger Please 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.

These batteries work wonderful last a long time, but I would like the charging to be a little bit faster just a heads up, but they last a long time

I recently purchased EBL's 2500 AA NiMH batteries (ASIN B08XP7ZC8K) because they were less expensive, advertised 2500mAh capacity, and were 30% less expensive (as of May 2024), and I liked the colors. Since it seemed a little too good to be true, I decided to thoroughly test and compare the brands. The data is worth sharing. Testing Methodology: All tests were performed with an ISDT N16 charger. It is an intelligent charger. Two rounds of testing were performed at three charge rates: 0.5A, 1.0A, 1.5A. The NiMH charging strategy starts with a lower voltage and increases the voltage over time and considers temperature as it charges, up to the set charge rate. "Activation Charge" for NiMH cells was enabled, which drains the battery first, then performs a full charge. This should result in a consistent charge pattern (no partial charges) and level the playing field as discharging was uniform. The charted results omit the single worst charge, while the table includes all results. The batteries have not been used in anything other than the ISDT N16 charger. Results: * All cells charged to roughly 2574mAh on average, at all charge rates * The product exceeds advertised 2400mAh capacity by 174mAh, on average, at all charge rates. * At a 1.5A charge rate, the charge variation between the least & most charged cells was the greatest * At a 0.5A charge rate, the variation was the lowest Comparing this to EBL's offering, Amazon's 2400mAh battery had a tendency to exceed the stated design capacity, which I've observed as between 2562-2580mAh on average and as high as 2848mAh. This, from the same charger, at the same charge rates, and with the "activation" option enabled. Cost comparison (as of May 2024) highlights some interesting data: * AZ 2400 12-pk @ $21.79 - $1.82/cell - @2574mAh realized capacity = 0.07 cents per 100mAh * EBL 2500 12-pk - $15.28 - $1.27/cell - @2100mAh realized capacity = 0.06 cents per 100mAh * Capacity as deciding factor: Amazon "wins" as they hold 18% more charge, but initial purchase cost is 30% more than EBL. When considering cost per cell's capacity, the difference is negligible and both brands stand on equal footing. Amazon's brand charges more consistently, holds more charge/out-performs their stated specification, and has more consistent voltage at rest. * Cost as deciding factor: EBL "wins" on price as the initial purchase cost is less expensive than Amazon by 30%. However, EBL's cells hold 18% less charge than Amazon and fall short of charging to EBL's stated capacity by 16%. If EBL's cells charged more consistently and could be fully charged to capacity, they would easily represent the better overall value. * Charging: EBLs perform better at a higher 1.5A charge rate and also charge more quickly. Amazon's batteries perform better at a 0.5A charge rate which takes longer. However, Amazon's variability at 1.5A charging (360mAh variance) is only *slightly* worse than the best EBL 1.5A result (324mAh variance). EBL's variance at 0.5A charge rate is 644mAh, which is 2.25x worse than Amazon at 287mAh variance. Amazon's product performance is consistently consistent.

Bonne qualité. Conserve sa charge.

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.

Great product at a descent price. Hold their charge well. Tight squeeze in some products

I’ve been genuinely impressed with Amazon Basics AA and AAA batteries. They deliver consistently strong, reliable power across everything I’ve used them in — from TV remotes and wireless keyboards to game controllers, smart home sensors, and kids’ toys. Performance has been comparable to far more expensive branded batteries, with no noticeable drop-off in power or premature failures. What really stands out is their reliability over time. They hold charge well in low-drain devices, don’t leak, and feel dependable even when left installed for months. For everyday household use, they simply work exactly as you’d expect a good battery to work — no fuss, no surprises. The value proposition is exceptional. You get dependable performance at a price that makes sense, especially if you go through batteries regularly. They’re ideal for bulk buying without feeling like you’re compromising on quality. Overall, these are batteries you can buy with confidence. Practical, reliable, and excellent value — Amazon Basics AA and AAA batteries have become my default choice and I see no reason to switch back to more expensive alternatives.
