The Amazon Basics rechargeable AA NiMH batteries have been very reliable over the years. They function well in a wide range of devices and hold a solid charge. Charging speed is reasonable, and they do not get excessively warm while charging when used with a proper charger, I use a Panasonic charger. Battery life is good for high drain devices, and they have held up well over time with repeated recharging.

Overall, durable, dependable, and a great long term alternative to disposable batteries.

Great batteries. They have not disappointed me yet. Take a charge well. Function as expected. They give great power all the way down to zero.

Overall, a great choice for rechargeable batteries and at great cost.

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.

I use a lot of batteries, especially during the thanksgiving and Christmas days. But, I do use them year-round. My neighbor had the Amazon battery charger and the batteries and she gave me an extra one. I loved it. I ended up buying two more for myself. The batteries, last a decent amount of time, but the good thing is you don’t have to throw them out. You just recharge them. And they recharge within a few hours. I would highly recommend this to anyone who uses Aa or AAA batteries. It will save you money!

I literally charged these Amazon Basics rechargeable batteries for the SECOND time a couple weeks ago, I purchased a couple of packs hoping to save $ while keeping my electronics going with fresh batteries but I learned fairly quickly that they will not hold a charge if they sit for any period of time after charging them (like within a week) not to mention the juice runs out of them quickly after all that time waiting for them to charge.😩 I wish I could find some affordable rechargeable batteries that actually work well.

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 use these in low-drain LED under-shelf lighting. They get recharged about once a month. I have been using rechargeable AA lighting in my home and workshop for nearly two decades and while there have always been a couple here and there that fail quickly, I also have many previous-gen Amazon Basics AA batteries (the ones with black labels) that are more than 12 years old in daily use and still successfully recharging each and every month. Those old batteries will probably outlast these new ones. About 1 in 5 of the current-generation batteries has failed to charge after just 2 or 3 charges. They all charged from the half-charge they shipped with to full successfully, and recharged again about a month later. Then I noticed one day one of the lights suddenly dimmed from full-brightness to barely-lit. I took the batteries out and tested them. Two tested at 1.2 volts, just like they should. The third tested at less than 0.3 volts. I put it on the charger and the charger rejected it as "unable to charge". A few days later another light did the same thing. Again, one of the batteries had dropped to near-zero while the other two were normal, and again the charger rejected the battery. So far about 20% of all these batteries I bought in the past few months have failed. The batteries that work, work well. But the high failure rate makes me wonder just how long I can count on them to work.
