Amazon Basics 12-Pack Rechargeable AA NiMH Batteries, 2000 mAh, 1.2V, Low Self Discharge, Pre-Charged, Recharge up to 1000x Times

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'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.

This came in handy but they didn't last long the

These work pretty well for the value. We switched over to rechargeable about 2 years ago because we felt like we were burning through batteries right and left. These work well for kids toys, basic flashlights, normal household items. The only issue we have is you cannot really charge and store them, you need to charge right before use or they seem to lose charge over time, that’s mildly inconvenient, but as long as we’re not in urgent need of battery power, we can charge them for a few hours and than toss them in whatever we need. We do keep a pack or regular batteries on hand for urgent needs.

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.

These rechargeable batteries work great and hold a charge for about 2 weeks plus in my outdoor solar lights.

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.

These are always at a great price point and last as long as much more expensive brands. I use them in clocks, remotes, solar lights and many more uses.

Pilas buenas y funcionales, sin problemas. Buen precio.

J’utilise ces piles Amazon Basics depuis plusieurs mois pour différents appareils (télécommandes, lampe torche, accessoires photo). Elles arrivent 📦 préchargées et sont prêtes à l’emploi immédiatement, ce qui est pratique. ✅ Points forts : Capacité réelle proche des 2000 mAh annoncés Rechargeables jusqu’à 1 000 cycles ♻️ Bonne tenue de la charge dans le temps Prix compétitif pour un lot de 4 ⚠️ Points à noter : Comme toutes les NiMH, légère perte de charge après plusieurs mois sans usage 💡 Mon expérience : Après plusieurs cycles de recharge, l’autonomie reste stable. Idéal pour remplacer les piles jetables et réduire les déchets. Je les utilise aussi dans un flash photo, elles tiennent bien même en usage intensif. En résumé, un excellent rapport qualité/prix pour ceux qui veulent passer au rechargeable. Je recommande sans hésitation.

He estado cierto tiempo buscando un juego de pilas recargables que pudiera usar para alimentar una colección cada vez mayor de aparatos que necesitan baterías para hacer algo. Esto, lógicamente, me pasa después de Navidad, cuando los juguetes de los niños, las luces, los cacharros electrónicos y cualquier cosa con un botón de encendido piden docenas de pilas que no tengo, y llega a un punto en el que he perdido la cuenta de todos los paquetes que he tenido que comprar, y ahora tengo un cementerio de pilas gastadas que parece un almacén nuclear. Este paquete de pilas, sin grandes promesas al ser la opción de Amazon Basics, resulta que ha sido lo que necesitaba, ni más ni menos. Son pilas básicas, sin florituras, pero cumplen su función perfectamente, y lo sé porque tras usarlas en varios dispositivos y someterlas a ciclos continuados de carga y descarga (los juguetes de los niños son devoradores de baterías sin piedad), puedo decir que su duración es más que decente, aguantando sin problemas sesiones prolongadas de uso antes de necesitar pasar de nuevo por el cargador. Lo que más me ha convencido es que, incluso después de varias recargas, siguen funcionando de manera fiable y no dan la sensación de no duran nada a medida que las vas recargando, al menos de momento y tras un uso extensivo de un par de semanas. En resumen, una opción práctica para el día a día con buena relación calidad-precio, ideal si tienes niños, dispositivos tragapilas o simplemente quieres dejar de vivir pendiente de comprar pilas todo el rato y gastar un dineral.
