Amazon Basics 16-Pack Rechargeable AA NiMH Batteries, 2000 mAh, 1.2V, Low Self Discharge, Pre-Charged, Recharge up to 1000x Times

These Amazon Basics rechargeable AA batteries have completely exceeded my expectations and proven to be one of the best purchases I've made this year! I cannot express enough how impressed I am with their performance, reliability, and incredible value. If you're looking for high-quality rechargeable batteries that won't break the bank, your search ends here! The battery life is absolutely phenomenal. With a 2000 mAh capacity, these batteries hold an impressive charge that lasts significantly longer than I anticipated. I've been using them in everything from my TV remotes and wireless keyboards to high-drain devices like digital cameras and game controllers, and they perform flawlessly in every application. The longevity is truly remarkable - I've gone weeks without needing to recharge them in my everyday devices. What really sets these batteries apart is their incredible recharge capability. The fact that they can be recharged up to 1000 times is simply outstanding! This makes them extraordinarily cost-effective and environmentally friendly. I've calculated that these batteries will save me hundreds of dollars over their lifetime compared to constantly buying disposable batteries. The environmental impact reduction is an added bonus that makes me feel good about this purchase. The 24-pack quantity is perfect for stocking up and ensuring I always have fresh batteries ready to go. I keep some in rotation for immediate use and have backups charging and ready for when I need them. The packaging is secure and the batteries arrive in perfect condition every single time. The Amazon Basics quality is evident from the moment you open the package. The NiMH technology delivers consistent power output throughout the discharge cycle. My devices run at peak performance from full charge until it's time to recharge - there's no gradual power decline that affects functionality. This reliability is crucial for my professional equipment and daily-use electronics. I trust these batteries completely. What impresses me most is how well these batteries maintain their charge when not in use. The low self-discharge means I can keep them in storage and they're ready when needed months later. This is a game-changer for emergency flashlights and backup devices. The reliability and convenience factor is unmatched. These batteries are an absolute must-have for anyone using AA battery-powered devices!

I've been using these for a while now and recently replaced all traditional batteries with these rechargeable ones. They work great! Hold the charge well and overall performance is fantastic. Price point is low enough for me to say these are an incredible value.

This came in handy but they didn't last long the

4 stars for Great battery, quick charging and good price. 1 star for delivery being a day late, drove right by my house and came back the next day. Out of 18 deliveries this week, 7 were late.

Lots of reviews here, but few if any with data. Here’s the summary of my data: 12 new batteries were tested and all met their claims. Out of the box charge was a low of 1730 mAh to a high of 1820 mAh. Refreshed capacity was from 2050 mAh to 2130 mAh. Percent capacity after 28 days ranged from 88% to 91%. Refreshed capacity after 28 days was from 2030 mAh to 2140 mAh. I do not have the time to measure the claimed 80% capacity after 2 years, or the claim that the batteries can be recharged 1000 times. The self-discharge rate of these batteries is as low as any brand I have tested or have seen tested. I think these are fine batteries and a good value, especially when on sale. Sometimes these can be found for close to $1 per battery. Yes, I will buy them again when I need more rechargeable batteries. Details of test: I bought 12 batteries on 21 November, 2023. I tested 4 at a time in a LaCrosse BC-900 battery charger using the “Refresh” mode. Discharge rate = 500 mA, charge rate = 1000 mA. The batteries were discharged until the voltage dropped to 0.90 V. Both batteries and charger were fan cooled during the tests. Battery temp when being discharged was 22° C. Battery temp when being charged was 30° C. Batteries were stored for 28 days in a 20° C room, and then retested. Comments: The charge and discharge rates (1000 mA & 500 mA) are reasonable for these batteries. The charge rate is about ½ C, which is half the charge rate usually specified for the number of charge-discharge cycles (in this case, 1000). The discharge rate is middle of the road for the devices these batteries are often used in. Most devices with motors will discharge at a higher rate, most small purely electronic devices will use less than 500 mA. Low Self-Discharge (LSD) batteries loose most of their charge in the first week; going from 100% to less than 94%. After one week, the self-discharge drops off markedly. If stored in a refrigerator at 5° or less, the self-discharge should be a little less. However, do not freeze the batteries. And, as you may have guessed, I am an engineer. UPDATE on 19 November, 2024 I ordered 24 more of these batteries, and after charge cycling them 3 or 4 times, I tested them. All batteries exceeded their 2000 mAhr rated capacity, with a range of 2050 mAhr to 2200 mAhr. These are good batteries at a good price.

These are very reliable batteries. I've purchased different sizes and this size before. They hold a charge well, and an excellent savings compared to alkaline batteries, and less batteries in the landfills. Do keep in mind of the voltage, depending on what you are using them for. Some people will say it doesn't matter because alkaline batteries lose some charge when first used, however, regular batteries are 1.5V, so if you are using an item that requires multiple batteries, you might run in to issues. Also, previously ordered batteries (AA and AAA) had a plastic holding container for every 4 batteries and I liked this since ends of 2 batteries touching can cause a fire. It was also just convenient having the little cases of them close by. I still appreciate rechargeable, and these are a good price for them.

These rechargeable batteries work great and hold a charge for about 2 weeks plus in my outdoor solar lights.

But... I've thrown a handful of these away out of the 48 I've purchased. Probably five or six, and those five or six probably had been charged an average of about five times. Seems like a high rate of failure to me. I tried to take the plunge and switch over entirely, but these also do not hold a charge anywhere near as long as conventional batteries. Certain things, like my door lock, I simply don't want to be changing batteries all the time. Also, there are certain items these won't work in at all. The batteries are the same exact overall length of conventionals, but the "nub" at the positive end is not as long. This creates fitment issues in some items. That said, these are more than economical enough to justify switching to rechargeables, even with the caveats listed above. I'm sure, like anything else, the faster people adapt, the better the product becomes. I'll hold out hope that this will be true and keep replenishing.

These are always at a great price point and last as long as much more expensive brands. I use them in clocks, remotes, solar lights and many more uses.

Pilas buenas y funcionales, sin problemas. Buen precio.
