Amazon Basics AAA Rechargeable Batteries (850 mAh, NiMH) — Tested Capacity, Performance & Matching Results I tested a full 12-pack of these AAA rechargeable NiMH batteries after a couple months of normal use in kids toys and various gadgets using a charge/discharge/charge analysis cycle, and the results were consistently strong, well above the rated capacity, with only one weaker outlier. Test Setup * ISDT N8 Series smart battery charger * Full analysis cycle (charge → discharge → recharge) * 0.3A charge/discharge rate * 0.90V cutoff voltage * Temperature range: 28°C – 33°C Measured Results * Average Capacity: 1,079 mAh * Highest: 1,171 mAh * Lowest: 964 mAh All cells exceeded the rated 850 mAh capacity, with most landing comfortably above 1,100 mAh, which is excellent performance for AAA NiMH batteries in this price range. Internal Resistance & Performance * Average: 193 mΩ * Most cells: 180–200 mΩ * One outlier: higher resistance, lowest capacity Lower internal resistance helps with performance meaning less voltage sag in high-drain devices like controllers, camera accessories, and other electronics. Cell Matching Results: After testing, I grouped the batteries by performance: * Top tier (7 cells): high capacity, closely matched * Mid tier (4 cells): slightly lower capacity but still good * 1 outlier: lower capacity and higher resistance This is typical for budget rechargeable batteries but still allows for multiple well-matched sets. What Stands Out * Consistently exceeds rated capacity * Good overall cell matching * Only one weak cell in the pack * Works well for both high-drain and everyday devices Final Thoughts These Amazon Basics AAA rechargeable batteries are a solid high-capacity option at a very reasonable price. With basic matching and rotation, they can deliver performance close to more expensive brands. The cons to this being that this is effort you generally don’t have to expend with more expensive premium Japanese made cells. However, if the cost savings are worth it to you these are a great value for the money and outperform a lot of the other Chinese-made budget cells. Some of whom wildly overstate their actual capacity. Rating: 4.5 / 5 (Can’t give half a star Amazon rating. Hence the five star rating) Please note: All NiMH rechargeable batteries have a break-in period when new. This is usually 3-5 full charge/discharge cycles (premium low self discharge Japanese-made cells generally only need one or two cycles). A good smart charger with a “refresh” or “activation” function can do this for you (it can take several hours) or it will naturally happen over time as you use them. This just means that capacity will increase after break-in so rechargeable batteries aren’t necessarily defective if they don’t meet their rated capacity straight out of the package. Why grouping similar performing batteries, if possible, makes a difference in real-world performance. When using rechargeable batteries in devices that use multiple batteries like controllers the load is shared by both batteries. Pairing a strong cell with a higher capacity and lower resistance with a weaker lower capacity higher resistance cell means the weaker cell is going to deplete and drop voltage faster. The stronger cell ends up shouldering more of the workload. This all means you get less time between recharges. None of this, of course, is strictly necessary, but if possible analyzing and grouping together similar performing batteries will increase their lifespans and give you more usage time between recharges. Once again not strictly necessary but something to note.

These batteries have never disappointed me. They are reasonably priced, and they are ready-to-use right out of the box. I wish the price were lower, but everything is more expensive today. I would love it if the batteries lasted a bit longer. I always buy rechargeable batteries, but I seem to be ordering them more frequently.

These AAA’s work great. No problems recharging. I’ve had a pair in a Roku remote for nearly a year. I use them to power a wireless mouse and keyboard for about the same time. When using in my headlamps they last for hours without needing a charge. Unlike the AA’s, these are the same size as a typical non-rechargeable AAA. The AA’s are slightly wider than your typical AA. They put out 1.2v rather than the standard 1.5v so some equipment may not work with them, but I haven’t ran into that issue. I would buy them again if I need to. They absolutely save money in the long run

When I ordered the 16 pack AAA batteries I really didn't realize that I had so many different devices/gadgets that used this small size battery. But, there it is in my picture. From a DVR controller, graphing calculator, bike taillight, walkie-talkie, TV remote, analog to digital converter box remote, to a Roku remote. Not included in the photo were a flashlight, kitchen timer, electrical toothbrush, wireless mouse, moustache shaver, etc.....and the list goes on and on. As you can see I've always used the Amazon Basics brand. Amazon should compensate me for giving them free advertisement. LOL. Its quality is superb and hasn't given me any trouble at all. There is no issues with battery leakage and keeps its battery charged for quite some time. It has saved me countless trips to the store just to get fresh new batteries and literally saved me tons of money not having to buy so many. And, I might also add, Mother Earth is thanking me for being less of a polluter by having less batteries in the landfills. I would recommend this brand, Amazon Basics, to everyone. It is also highly recommended to buy a reputable battery charger that can charge both AAs and AAAs like my charger on the bottom right of the photo. It is very useful and stops charging when it is done so it won't overheat.

Great quality and great price, well worth the money

These 24 rechargeable batteries are a great value for anyone who needs a reliable power source for devices.

I love the convenience of having a pack of 24—never running out of batteries feels like a win, and it’s really easy to keep extras charged and ready to go. The build quality is solid, and I haven’t had any issues with them losing charge too quickly or not holding power. Plus, being rechargeable, they’re better for the environment and save me money in the long run. The only thing to note is that they take a bit longer to charge than disposable batteries, but that's the tradeoff for all the positives. Overall, a fantastic and cost-effective solution for all your battery needs!

Good price

Pilas buenísimas, funcionan perfecto en mi cargador marca "Energizer" y la batería les dura bastante, las compré para mi control de videojuegos y demás controles del hogar, les dura meses la carga.

I bought these rechargeable AA batteries specifically to use as backup power in my Zoom F8n Pro field recorder. My recorder is normally powered from a V-mount battery via a Hirose cable, but having these installed means the recorder stays powered while I swap V-mount batteries, so there's no interruption to recordings or timecode. They've been completely reliable in that role. The recorder seamlessly switches to the internal AA batteries during a battery change and then back to external power once the new V-mount is connected. It's a simple setup, but one that's saved me from having to stop and restart recordings. The batteries hold their charge well and have performed consistently every time I've needed them. Although they spend most of their time sitting inside the recorder as a backup power source, they've always had enough capacity to do exactly what's required when the external power is disconnected. I've also found them to recharge without any issues, and after repeated charge cycles they haven't shown any noticeable drop in performance. If you're using a Zoom F8n Pro or any other recorder that accepts AA batteries alongside external power, these are an excellent choice. They've given me confidence that I can swap my V-mount batteries during a shoot without risking an unexpected shutdown, and for that reason alone they've been well worth buying.
