These Amazon Basics rechargeable AA batteries have completely exceeded my expectations and proven to be one of the best purchases I've made this year! I cannot express enough how impressed I am with their performance, reliability, and incredible value. If you're looking for high-quality rechargeable batteries that won't break the bank, your search ends here! The battery life is absolutely phenomenal. With a 2000 mAh capacity, these batteries hold an impressive charge that lasts significantly longer than I anticipated. I've been using them in everything from my TV remotes and wireless keyboards to high-drain devices like digital cameras and game controllers, and they perform flawlessly in every application. The longevity is truly remarkable - I've gone weeks without needing to recharge them in my everyday devices. What really sets these batteries apart is their incredible recharge capability. The fact that they can be recharged up to 1000 times is simply outstanding! This makes them extraordinarily cost-effective and environmentally friendly. I've calculated that these batteries will save me hundreds of dollars over their lifetime compared to constantly buying disposable batteries. The environmental impact reduction is an added bonus that makes me feel good about this purchase. The 24-pack quantity is perfect for stocking up and ensuring I always have fresh batteries ready to go. I keep some in rotation for immediate use and have backups charging and ready for when I need them. The packaging is secure and the batteries arrive in perfect condition every single time. The Amazon Basics quality is evident from the moment you open the package. The NiMH technology delivers consistent power output throughout the discharge cycle. My devices run at peak performance from full charge until it's time to recharge - there's no gradual power decline that affects functionality. This reliability is crucial for my professional equipment and daily-use electronics. I trust these batteries completely. What impresses me most is how well these batteries maintain their charge when not in use. The low self-discharge means I can keep them in storage and they're ready when needed months later. This is a game-changer for emergency flashlights and backup devices. The reliability and convenience factor is unmatched. These batteries are an absolute must-have for anyone using AA battery-powered devices!

I use these Amazon Basics rechargeable AA batteries with a compatible charger, and they have worked very well for my needs. The biggest advantage is convenience. I can keep a charged set ready, swap them into a device when needed, and place the depleted batteries back on the charger. They may not always last as long per charge as some conventional disposable batteries, but I no longer need to constantly keep new AA batteries on hand. That makes them especially useful for frequently used household devices. I have not calculated the exact cost savings, but the ability to recharge and reuse the same batteries has made them a practical and dependable purchase. I would recommend them to anyone who wants a simple rechargeable battery system for regular household use.

These rechargeable AA batteries exceeded my expectations. They hold a charge for a long time, come pre-charged, and work great in my remote controls, toys, and other household devices. Being rechargeable up to 1,000 times makes them an excellent value. Highly recommended!

First of all they are just a fraction of a millimeter bigger in diameter as others have noted. So they fit a bit tight in some devices. But in addition to this the positive button on the top of the battery is a fraction of a millimeter shorter with respect to the battery's outer casing. Please note the attach picture. This can cause the positive top of the battery to fail to make a connection to the battery compartment on some devices, where the positive connector is recessed a bit more then typical. The Eneloop brand does not have this problem. These are a good value for the price though. So keep a couple sets of the Eneloop batteries around for these types of situations. These will power a set of those led fairy lights for ten hours or so per charge, depending on how many lights are on the strand. They charge well using the Panasonic Eneloop chargers. Given the price and usability in many devices they earn 4 stars.

Lots of reviews here, but few if any with data. Here’s the summary of my data: 12 new batteries were tested and all met their claims. Out of the box charge was a low of 1730 mAh to a high of 1820 mAh. Refreshed capacity was from 2050 mAh to 2130 mAh. Percent capacity after 28 days ranged from 88% to 91%. Refreshed capacity after 28 days was from 2030 mAh to 2140 mAh. I do not have the time to measure the claimed 80% capacity after 2 years, or the claim that the batteries can be recharged 1000 times. The self-discharge rate of these batteries is as low as any brand I have tested or have seen tested. I think these are fine batteries and a good value, especially when on sale. Sometimes these can be found for close to $1 per battery. Yes, I will buy them again when I need more rechargeable batteries. Details of test: I bought 12 batteries on 21 November, 2023. I tested 4 at a time in a LaCrosse BC-900 battery charger using the “Refresh” mode. Discharge rate = 500 mA, charge rate = 1000 mA. The batteries were discharged until the voltage dropped to 0.90 V. Both batteries and charger were fan cooled during the tests. Battery temp when being discharged was 22° C. Battery temp when being charged was 30° C. Batteries were stored for 28 days in a 20° C room, and then retested. Comments: The charge and discharge rates (1000 mA & 500 mA) are reasonable for these batteries. The charge rate is about ½ C, which is half the charge rate usually specified for the number of charge-discharge cycles (in this case, 1000). The discharge rate is middle of the road for the devices these batteries are often used in. Most devices with motors will discharge at a higher rate, most small purely electronic devices will use less than 500 mA. Low Self-Discharge (LSD) batteries loose most of their charge in the first week; going from 100% to less than 94%. After one week, the self-discharge drops off markedly. If stored in a refrigerator at 5° or less, the self-discharge should be a little less. However, do not freeze the batteries. And, as you may have guessed, I am an engineer. UPDATE on 19 November, 2024 I ordered 24 more of these batteries, and after charge cycling them 3 or 4 times, I tested them. All batteries exceeded their 2000 mAhr rated capacity, with a range of 2050 mAhr to 2200 mAhr. These are good batteries at a good price.

Initial Impressions: The batteries arrived nicely packaged in a cardboard box, with six, individually wrapped packages of four cells each. My testing process for new cells is pretty extensive and these Amazon Basic’s pre-charged cells, at least on the initial round of testing prove to be of very good quality. All 24 cells were weighed for consistency. All of the cells measured in at 27 grams, plus or minus 0.03 grams indicating that the manufacturing quality for the active material is highly consistent. The 24 cells then were put through an initial capacity discharge test utilizing an ISDT 24 channel charger. 20 of the 24 cells showed an initial capacity ranging from 1890 to 1920 mAH, and four cells showed an initial capacity of between 1310 and 1400 mAH. The cells are rated by Amazon as 2000 mAH cells, so the 20 cells came pre-charged at 95% full. I assume that the four outliers were not charged fully at the factory. All 24 cells were once again placed in the ISDT charger, this time, set for activation charge, where the cells are charged and discharged three times in succession to distribute the electrolyte equally within the cell, and fully charge the cell to its maximum capacity. All 24 cells charged to beyond the Amazon rated capacity with the average capacity at 2130 mAH. The fourth round of testing involved a torture test utilizing a West Mountain Radio Computerized Battery Analyzer. Each battery underwent a mission profile test, at constant current, until the output voltage dropped to cutoff. Again, each battery, under constant load, exhibited a measured capacity of between 1920 and 1975 mAH. The fifth round of testing was a random selection of four cells to be put back on the CBA and a discharge test ran, again at constant current, plotting the results of all four cells on the same graph. All four cells had a discharge profile that is extremely consistent, and flat across the entire time until the cell was exhausted. The sixth round involves a self-discharge test, again four random cells were selected and were measured for their open-circuit voltage. After 48 hours, these same cells were measured again, and their open-circuit voltage compared. The self-discharge was again, very consistent, and was on average 0.03V from the initial measurement. While 48 hours is a very short period to test for self-discharge over time, it’s encouraging to see that there was little in the way of voltage loss. I set two random cells aside, that will be measured at 30, 60, 90, and 180 days to see if this low discharge is maintained over an extended period of time. At this point, after the testing performed, I would rate these cells as excellent quality, and an excellent price point. Most of my cells are Eneloop, and I was curious to see how the Amazon cells would perform compared to the Eneloop and the Ikea Ladda cells, which are the same. I’ve been using rechargeable cells since the NiCd days, as there is something inherently wrong with the idea of buying something only to toss it in the trash a few days or weeks later. Add to that all Alkaline batteries will eventually leak and destroy what they are installed in, I am happy to see that there is a lower cost, quality cell available. Only time will tell if they are truly an equal to the Eneloop brand of battery, most of mine are still going strong after almost 15 years of pretty demanding service.

I will fully charge these batteries, take them directly off of the charger and it says they are fully charged put them in something and they will be dead! These are the worst batteries I have ever bought complete waste of money no giving a review

They are fatter than a standard battery so if you have a slot load type device they may get stuck or not fit at all. The positive terminal(the nub on the end) doesn’t protrude as far as a standard battery. Depending on your device they may not make contact with the metal plate. They’re fine batteries if they’re compatible with what you put them in but it’s a shame that they only work in about 60% of the things I’ve tried them on so far.
