Amazon Basics Rechargeable AA Batteries, 8-Count, 2000 mAh, NiMH, Recharge up to 1000x Times, Pre-Charged

So, I recently picked up a pack of Amazon Basics Rechargeable AA Batteries, and let me tell you, these little guys are a lifesaver! If you're tired of constantly buying disposable batteries, these are definitely worth checking out.First Impressions:The pack comes with eight batteries, and they're pre-charged, which is awesome because you can use them right out of the box. No waiting around to charge them up before you can power your gadgets. They look pretty standard, but hey, they're batteries—it's what's inside that counts!Performance:Each battery is 2000 mAh, which means they hold a decent amount of power. I've used them in everything from TV remotes to wireless mice, and they last a good while before needing a recharge. It's nice not having to swap out batteries every other week. Plus, they recharge up to 1000 times, so you'll be using these for ages.Ease of Use:Charging them is a breeze. Just pop them into any NiMH charger, and you're good to go. They charge up relatively quickly, so you won't be waiting forever to get back to your gadgets. I love that I can always have a couple charged and ready to go, so I'm never caught off guard with dead batteries.Value for Money:Honestly, these are a great deal. Considering how many times you can recharge them, you're saving a ton compared to buying disposables. Plus, it's better for the environment, which is a win-win in my book. They're affordable, reliable, and they do the job without any fuss.Overall Thoughts:If you're still using disposable batteries, it's time to make the switch. The Amazon Basics Rechargeable AA Batteries are a solid investment. They're convenient, cost-effective, and they keep your devices running smoothly. Whether it's for your gaming controller or your kid's toys, these batteries have you covered. Give them a shot—you won't regret it!

Use these in our samsung push pull biometric door handle.They last years for us.Charge up quickly. Keep a charge decently. But if sitting for a month remeber to keep them charged consistently.Havent had any problems.Even lasted about 4 hours in one of battery powered led camera lights that eats batteries for breakfast.Quality is top notch and saves money (even if inital investment is kind of pricey) these keep going charge after charge.

Initial Impressions:The batteries arrived nicely packaged in a cardboard box, with six, individually wrapped packages of four cells each. My testing process for new cells is pretty extensive and these Amazon Basic’s pre-charged cells, at least on the initial round of testing prove to be of very good quality.All 24 cells were weighed for consistency. All of the cells measured in at 27 grams, plus or minus 0.03 grams indicating that the manufacturing quality for the active material is highly consistent.The 24 cells then were put through an initial capacity discharge test utilizing an ISDT 24 channel charger. 20 of the 24 cells showed an initial capacity ranging from 1890 to 1920 mAH, and four cells showed an initial capacity of between 1310 and 1400 mAH. The cells are rated by Amazon as 2000 mAH cells, so the 20 cells came pre-charged at 95% full. I assume that the four outliers were not charged fully at the factory.All 24 cells were once again placed in the ISDT charger, this time, set for activation charge, where the cells are charged and discharged three times in succession to distribute the electrolyte equally within the cell, and fully charge the cell to its maximum capacity. All 24 cells charged to beyond the Amazon rated capacity with the average capacity at 2130 mAH.The fourth round of testing involved a torture test utilizing a West Mountain Radio Computerized Battery Analyzer. Each battery underwent a mission profile test, at constant current, until the output voltage dropped to cutoff. Again, each battery, under constant load, exhibited a measured capacity of between 1920 and 1975 mAH.The fifth round of testing was a random selection of four cells to be put back on the CBA and a discharge test ran, again at constant current, plotting the results of all four cells on the same graph. All four cells had a discharge profile that is extremely consistent, and flat across the entire time until the cell was exhausted.The sixth round involves a self-discharge test, again four random cells were selected and were measured for their open-circuit voltage. After 48 hours, these same cells were measured again, and their open-circuit voltage compared. The self-discharge was again, very consistent, and was on average 0.03V from the initial measurement. While 48 hours is a very short period to test for self-discharge over time, it’s encouraging to see that there was little in the way of voltage loss. I set two random cells aside, that will be measured at 30, 60, 90, and 180 days to see if this low discharge is maintained over an extended period of time.At this point, after the testing performed, I would rate these cells as excellent quality, and an excellent price point. Most of my cells are Eneloop, and I was curious to see how the Amazon cells would perform compared to the Eneloop and the Ikea Ladda cells, which are the same.I’ve been using rechargeable cells since the NiCd days, as there is something inherently wrong with the idea of buying something only to toss it in the trash a few days or weeks later. Add to that all Alkaline batteries will eventually leak and destroy what they are installed in, I am happy to see that there is a lower cost, quality cell available. Only time will tell if they are truly an equal to the Eneloop brand of battery, most of mine are still going strong after almost 15 years of pretty demanding service.

So far so good....They charge up, they work, the last.But believe the reviews when they say some of them are larger than others. Unfortunately I believed those that quipped at the reviews about some of these batteries being oversized... I found out the hard way and almost ruined a mouse for my computer because the battery got stuck in it 👀.Not all the batteries are odd sizes, most of them are fine. But beware... There are batteries in this package that are larger than they should be and they will get stuck in things so be careful. They do not get stuck in the charger that I bought but in a tight space like a mouse they can get stuck.

My son got a car race track and let me tell you, it uses a lot of battery... These batteries are great since we can keep recharging them after use, they last a lot!! It also feel great knowing that you are helping the planet on reusing a product... They are compatible with a lot of things and toys. Easy to use too.

The body of these batteries is exactly as large as the spec. That's because they have a lot of chems inside. I recommend for high power use when an alkaline won't put out the power.
