24-Pack Rechargeable AA NiMH High-Capacity Batteries, 2400 mAh, 1.2V, Low Self Discharge, Pre-Charged, Recharge up to 400x Times

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.

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.

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 have a couple trash cans with automatic lids in the house that use multiple AA batteries, so I decided it was high-time to get some rechargeable batteries for those devices. These work just fine but there are 2 issues that are important to note: 1) they are slightly larger in diameter than a typical AA battery, so they can be a bear to install and remove from some devices. Also, the larger diameter can make them hang-up and not move smoothly in the battery compartment causing them not to contact the electrical connections, so you have to push them around to get continuity. 2) they don't have the lifespan of an Alkaline battery. In my bathroom trash can, for instance, alkalines last about 90 days. These batteries can barely make it 30 days before they need a charge. However, I've run the batteries through about 6 months of use and they keep recharging happily, so the value has already been established at the trade-off of battery life. In all, I am happy with them. i can certainly live with the shorter life, but would prefer them to be the same size as all other AA batteries.

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.

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.

I’ve bought these for yers in all sizes and like them. They’ll last quite a while as in many years. But if you look at the amount of energy they store in milliamps, it is less than some namebrand ones, but sometimes more than the offbrand Chinese ones. So if you need more storage capacity, go to the name brands, but these are much more reliable value than any offbrand.

I use these in everything. they last for years they do lose overall battery life overtime but not fast enough that they are not cost efficient.

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.

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.

Ok, ale rzeczywiście średnica baterii trochę większa (grubsza) niż standard, więc nie wszędzie będą pasować.
