Amazon Basics Rechargeable AA Batteries, 16-Pack, 2400 mAh, NiMH High-Capacity Batteries, Recharge up to 400x Times, Pre-Charged

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.

These batteries work well and are a great value. I've been using them for several months, and they charge up, get used, and repeat the cycle over and over again. I'm happy with them.

I use a lot of battery operated LED lights throughout my house. Very difficult to run AC through the walls. (Cost). I've had rechargeable batteries for years and they have come in handy when power goes out. I have lights also in my closets. I haven't had to change them out in about 6 months. These rechargeable batteries do very well in your game controllers as well. I use these in my FLIR for work and they perform great. Also use them in my multimeters with no problems. All my remotes have either AAA, or double AA batteries. It's been years since I have bought a alkaline battery.It's very economical to use rechargeable batteries! I keep at least 45 AA's charged at all times. Rechargeables perform very well under load, and stored. It does advertise that they come charged, but they are not 100% charged. There is a reason why they do come with a charge!? If they had no charge, you could not recharge them, because your battery charger would not recognize them. You would just get a blinking light. You would have to jump start each one... (Check out YouTube for rebooting your dead batterys) do not throw them away, they still have life. The only negative thing I have to say about these rechargeable batteries that save's you money is... The climate crises zealots 👣... These people need to grow up! It's really a political statement. I just want to buy, or say something without it being politicized!? I highly recommend using rechargeable batteries. It is Earth friendlier, as well as cost-effective. We really don't need a stamp of approval to think that way... Do we?

Batteries work well and lasts long. Does not come fully charged so charge before use.

Review for AA size NiMH rechargeable cells.These are size AA Nickel Metal Hydride Batteries - actually cells, but I am nit-picking now. The cells arrived in good condition considering they were sold as used. They had a manufacture date of February 2024 and since it it now November they definitely needed a top-off charge. A smart charger is strongly recommended, save yourself a headache and don't use a cheapo charger. I use an EBL model EBL-907 smart charger which charges and monitors each cell individually.The charger showed a level of one bar for each cell at the beginning. The batteries, um cells took 2.5 hours to reach full charge and then showed a voltage of 1.45 volts, which is the same as other brands. To conclude, these are just as good as other brands and are a bargain too.
