Amazon Basics 12-Pack Rechargeable AAA NiMH High-Capacity Batteries, 850 mAh, 1.2V, Low Self Discharge, Pre-Charged, Recharge up to 500x Times

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.

Im SO glad I got these! Rechargeable batteries are the BEST! & these seem to be the same as the ones you buy in store that are super expensive & you only get like 4-8 of them.. insane!! Im so happy I decided to look on Amazon after buying just 4 from the store for $15+ with the small charger included.. I came across these and had to get them! Great deal/price, they work great and I got a bigger charger off Amazon also for a much better price than in store as well. Change all your regular batteries to these and save yourself a TON of money and time/headache! YOU'LL ALWAYS HAVE BATTERIES! Lol they charge quickly, last a good bit depending on what you put them in. So far though, for the uses I've had for them.. they last a good bit before they need charged again! Buy them! You wont be sorry! Save yourself some money!

Great product I have not had any issues so far. Really nice price for the quantity, at least I think so I feel I am a thrifty shopper.

I have a drawer full of AAA and AA of the Amazon rechargeables. I run the global team for a smart home product and conduct too many trainings and dems to be buying batteries all the time. Everytime I change the battery I consistently get a 85-95% level reading in my hub so I tested them separately and got the same reading. Since I can recharge them, I always take “fresh” +1 sets on the road and just keep a couple dozen each ready at all times. Just go in eyes open. They are not Energizer/Duracell quality every charge, it rest for your remotes and light items. If using for smart door locks, keep a couple on hand as charging ca take several hours. Overall, good price/quality and a lot less waste out there!

I purchased battery powered PIR sensor led lights here on Amazon. They take four batteries each and I have three of them. That's twelve batteries I'd need to power them all. Amazon Basics 24-pack AAA NiMH gives me batteries to power them all with extras. They seem to hold a charge good. I can run my PIR sensor led lights for about a week in the kitchen before they become dim. That's a high traffic area and those lights come on every time I'm near the kitchen cabinets.

Working great on my solar patio figurine! It’s very bright. They seem to last at least 6 hrs. most nights.

I have a few phone handsets whose rechargeable batteries needed to be replaced due to performance issues. I ended up giving these a try and they work great! They hold their charge well under daily use. I easily get three days use on a full charge. I'm happy!

Son muy buenas, su relación calidad precio valen la pena. Se recargan rápido.

Semble faire le taff Pas oublier de les recharger avant de les utiliser. Mais la durée de vie d’un accu ne peut se mesurer que le temps. On en reparle après 500 recharges Acheter en décembre 2025, ma première série de 3, bien recharger au départ: plates ~~> recharge. On est le 07 juin : donc six mois pour gérer une horloge, c’est sans plus. On verra à la fin 2026.

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.
