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!

Love these amazon batteries! I use them for all of my decorations and remotes around the house. My son uses them for the oculus remotes and his xbox controllers. They have many usues and a long life span. Oh my daughter uses them for her Canon Camera too and loves them. I have one of those first aid kit looking things that holds all the different types of batteries and I have them full of these, great batteries for the cost I could compare them to Energizer Lithium Ion batteries!

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.

Have to wear battery operated gloves. One-day use and regular batteries run out. This is a life and pocket saver .

I’ve been using these Amazon Basics rechargeable AA batteries for a while now in remotes, toys, and other household devices, and they’ve been very reliable. They hold a charge well and perform consistently between charges. I like that they come pre-charged and are ready to use right out of the package. Recharging them has been easy, and so far they haven’t shown any noticeable loss in performance. They do take a bit longer to charge compared to disposable batteries, but that’s expected with rechargeables. Overall, they’re a great value and a practical choice for everyday electronics. I would definitely buy these again.

bought to replace Chinese rechargeable batteries, and these are perfect, don't be tempted to buy cheaper ones as they simply don't work and in most cases are faulty

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.
