4-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 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.

These are great little rechargeable AAA batteries, and I’ve always been impressed with the Amazon Basics High Capacity line. These perform just as well as the AA versions I’ve used. They offer slightly higher energy capacity than many standard rechargeable AAAs, which is a nice plus, and their chemistry is still safe for typical household devices. Same size and fit as standard batteries, and just as durable a feel to them. They charge quickly, hold their voltage well, and overall are just incredibly handy to keep around the house. For the price, they’re an easy way to save a lot of money over time compared to constantly buying disposables. Solid performance at a great value. Would definitely recommend!

Dudaba pensando que dejarían de servir rápido, pero duran muy bien y llevo usando las todos los días recargando cada 3er día por más de un año y siguen como nuevas

Perfect for remotes and small led light fixtures. Holds a charge well and recharges in no time at all. Packaging is very good to the point of overkill

Goed product!

Compré este pack de pilas recargables Amazon Basics para usarlas en mandos, juguetes y algunos dispositivos pequeños de casa, y la verdad es que me han dado muy buen resultado. Tienen buena capacidad y aguantan bastante bien la carga, incluso después de varios ciclos de uso. Se cargan sin problema en un cargador estándar y mantienen bien la energía cuando no se usan durante un tiempo. Para mandos a distancia, ratones inalámbricos o juguetes infantiles van perfectas. Al venir en un pack de 12, tienes siempre recambios a mano, lo cual es muy cómodo y a la larga supone un ahorro frente a las pilas desechables. En resumen, unas pilas fiables, con buena relación calidad-precio y muy recomendables para el día a día en casa.
