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've been using these for a while now and recently replaced all traditional batteries with these rechargeable ones. They work great! Hold the charge well and overall performance is fantastic. Price point is low enough for me to say these are an incredible value.

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!

Addendum December 18, 2024 After cycling/testing them, they now are showing between 1950 and 2210 mAh with the majority at the rated 2000 or over. Only four or so under. A couple of drawbacks to this is that 1) I really can't use them and expecta "full charge" out of the box and 2) I've burned a few cycles out of the life of the battery to get them to the rated capacity. All in all, still a good value. Addendum December 14, 2024 I got my second set of these yesterday. I'm a little disappointed in this set. I have gotten a few "duds" in the AAA size but not with my previous AA order. I know they are advertized as pre charged but I rarealy trust that and generally test/cycle or simply charge them regardless. These batteries are rated 2000 mAh. With this set I charged them without conditioning or cycling. AFTER charging, several had a charge in the 400 mAn range. Two had a little over 1000 mAh. One batch of four was in the 300 mAh range. I'm going to put them back in the chargers. I originally charged them in a Lacrosse BC-9009 (and a couple of Lacrosse knockoffs), a Maha Powerex MHC-9000, and A Dlyful - A4. All charged at 200 mA. I'm going to run them through a test cycle and see if they come up nearer to 2000 mAh. I won't use the A4 as it can only cycle/test in one slot. I'll use a Dlyful UT1 instead but that one's lowest charge current is 250 mAh. July 2024 I've been using these in AAA size for a while. They do not seem as durable as my Fujitsus, Eneloops, or Laddas but they work. I've only started using these AAs recently but have noted that they do not last quite as long as the branded ones I listed above in remotes that an LCD screen. I've generally swapped out remote batteries at two week intervals. My first trail of these batteries lasted the full two weeks (no signs of fading) in two remotes but missed by a day on one giving me a low battery warning just a day under two weeks. For reference, I'm using them in Logitech Harmony 700 remotes controlling either ROKU or FireTV Stick devices. Overall, these batteries seem a really good value for the 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.

These are very reliable batteries. I've purchased different sizes and this size before. They hold a charge well, and an excellent savings compared to alkaline batteries, and less batteries in the landfills. Do keep in mind of the voltage, depending on what you are using them for. Some people will say it doesn't matter because alkaline batteries lose some charge when first used, however, regular batteries are 1.5V, so if you are using an item that requires multiple batteries, you might run in to issues. Also, previously ordered batteries (AA and AAA) had a plastic holding container for every 4 batteries and I liked this since ends of 2 batteries touching can cause a fire. It was also just convenient having the little cases of them close by. I still appreciate rechargeable, and these are a good price for them.

Great price, great item! Works well!!!!!!!

But... I've thrown a handful of these away out of the 48 I've purchased. Probably five or six, and those five or six probably had been charged an average of about five times. Seems like a high rate of failure to me. I tried to take the plunge and switch over entirely, but these also do not hold a charge anywhere near as long as conventional batteries. Certain things, like my door lock, I simply don't want to be changing batteries all the time. Also, there are certain items these won't work in at all. The batteries are the same exact overall length of conventionals, but the "nub" at the positive end is not as long. This creates fitment issues in some items. That said, these are more than economical enough to justify switching to rechargeables, even with the caveats listed above. I'm sure, like anything else, the faster people adapt, the better the product becomes. I'll hold out hope that this will be true and keep replenishing.
