Amazon Basics 8-Pack Rechargeable AA NiMH High-Capacity Batteries, 2400 mAh, 1.2V, Low Self Discharge, Pre-Charged, Recharge up to 400x Times

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.

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.

Absolutely loved these, High Capacity and Longer Battery Life. Good Value for what I bought them for and with having so many I rarely have to wait to charge, instead I just replace and charge the batteries as I go

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.

The Amazon Basics rechargeable AA NiMH batteries have been very reliable over the years. They function well in a wide range of devices and hold a solid charge. Charging speed is reasonable, and they do not get excessively warm while charging when used with a proper charger, I use a Panasonic charger. Battery life is good for high drain devices, and they have held up well over time with repeated recharging. Being able to recharge them hundreds of times makes them an excellent value for the money, especially from a trusted brand. Overall, durable, dependable, and a great long term alternative to disposable batteries.

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.

They r rechargeable and do take while to charge, but long lasting battery life

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
