I’ve been using these AA batteries for several years now, and they’ve proven to be reliable and long-lasting. I use two of them every night in my stereo earbuds to listen to white noise while I sleep, and they power the device for 2–3 days before needing a recharge. This routine has been going strong for about three years with the same set of batteries.Given their performance, I feel they were worth every penny when I first purchased them, and I plan to buy more for a family member to use as well. The only minor issue I’ve encountered is when the charger’s light flashes, which indicates the battery didn’t charge properly. However, this is a rare occurrence and doesn’t significantly affect the overall quality of the product.Over the past five years, I’ve only used two sets of the 4-pack, and out of all the batteries, only one has failed. That’s a pretty impressive track record, in my opinion. Overall, I’m extremely satisfied with this product and would definitely recommend it. Five stars!
