As a professional reviewer, I've had the opportunity to put the Amazon Basics 16-Pack Rechargeable AA NiMH High-Capacity Batteries (2400 mAh) through their paces. My findings are based on rigorous testing and comparison with other brands in the market. Upon unboxing, my initial impression was that these batteries are strikingly similar to the Sanyo eneloop XX batteries, both in appearance and specifications. This led me to believe that they might be rebranded versions of the same. To confirm my suspicion, I embarked on a series of tests using my La Crosse BC1000 Battery Charger/Analyzer. Here's what I found: Pros: + High Capacity: The batteries delivered an average capacity of 2555mAh after a few recharge/discharge cycles, exceeding the rated 2400mAh. This is a testament to their high-quality performance. + Quality Control: The tight spread between 2510 and 2610mAh across the batteries indicates excellent quality control. + Value for Money: At the time of writing, an 8-pack of Amazon High-Capacity AA batteries costs less than a 4-pack of eneloop XX batteries, making them a great bargain. + Long-Term Performance: After 5 months in storage, the batteries retained 85% of their original capacity, outperforming the Sanyo XX batteries in my previous tests. Cons: - Size: These batteries are slightly fatter than typical AA batteries, which might cause fitting issues in devices with extremely tight battery compartments. - Lifespan: While they perform excellently in the short term, these batteries seem to lose their ability to hold charge after a few years. If you're a heavy user, be prepared to replace them after 2-3 years. - Country of Origin: Some users have reported a drop in quality in batteries made in China compared to those made in Japan. In conclusion, the Amazon Basics 16-Pack Rechargeable AA NiMH High-Capacity Batteries (2400 mAh) offer excellent performance and value for money. However, their slightly larger size and shorter lifespan compared to other brands might be a deal-breaker for some users. Remember, the best battery for you depends on your specific needs and the devices you intend to use them in. Always consider these factors when making your purchase decision.

The Amazon Basics 8-Pack Rechargeable AA NiMH batteries offer solid performance at a reasonable price, making them a practical option for everyday household devices. After using them in items like remote controls, toys, and wireless accessories, they have proven to be reliable and convenient for regular use. These batteries charge without issue in standard NiMH chargers and hold a charge well for low- to moderate-drain devices. They are especially useful for items that require frequent battery changes, helping reduce waste and long-term costs compared to disposable batteries. Performance has been consistent, and they provide dependable power for routine tasks without noticeable drops in output. However, they are not the best choice for high-drain devices such as cameras, gaming controllers, or flash units, where higher-capacity premium rechargeables tend to last longer between charges. Charge retention over extended storage is decent but not exceptional, so they may need recharging if left unused for long periods. Build quality is acceptable, though they don’t feel as robust or long-lasting as more expensive branded alternatives. Overall, these Amazon Basics rechargeable AA batteries are a good value for everyday household needs. While they may not replace premium batteries for demanding electronics, they perform well for general use and are a cost-effective, eco-friendly option.

Along with a good charger, such as Xtar that can handle NiMH batteries these work very well in devices with high draw amperage. Unfortunately I have experienced that they do NOT fit well into flashlights that has tube enclosures because they are just a millimeter too large to fit correctly. They do provide a long charge and are perfect for most things but keep in mind that NiMH batteries are 1.2 volts fully charged and that Alkaline provides 1.5 volts per battery, this normally is a very small issue but if you use them in a device that happens to display how much battery life you have left these will show slightly lower than an alkaline would. For example when I use these in my Luna controller my app on my phone will show that I only have half battery capacity remaining but in reality they last longer than an alkaline would. The price of these are truly worth what you get, many recharge cycles and higher amperage than most other NiMH batteries!

I’ve purchased these batteries three times now, and I’m very happy with them. Compared to other more expensive brand-name, these Amazon Basics ones perform just as well. Even after a couple of years of frequent use and recharging, they still hold a good charge. Why spend more when these work perfectly and come at such a good price? Highly recommended!

All good

Great product at a descent price. Hold their charge well. Tight squeeze in some products

They hold charge well in low-drain devices, don’t leak, and feel dependable even when left installed for months.

You get dependable performance at a price that makes sense, especially if you go through batteries regularly. They’re ideal for bulk buying without feeling like you’re compromising on quality.
