Amazon Basics AA High-Performance Alkaline Batteries, 10-Year Shelf Life, Easy to Open Value Pack
[{'review_meta': 'Reviewed in the United States on October 22, 2018', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I tested the AA size Amazon brand battery to find out the actual usable capacity as compared to the AA Duracell Procell battery. The results showed that the Amazon battery is about 88 percent the capacity of the Duracell. If you calculate the cost per unit capacity, the batteries are almost identical. The Amazon battery was actually slightly more expensive when represented in cost per Watt-Hour. Because of this I would probably choose the Procell (if I can get a good price on it) just because it means less frequent battery changes. The Amazon battery is a surprisingly good battery though. You will probably barely notice the difference in capacity, so if you don't want to waste time shopping around then its a good choice.\n\nI also performed the same test on Duracell Copper Top, and Energizer Max. Their performance was nearly identical to the Procell. More interestingly, I tested the Energizer Ultimate Lithium AA cell. This cell was 4 times the cost of a procell at $1.27 per cell! However the capacity was only 1.5 times that of the Procell. So don't waste your money on these batteries, they're much more expensive per unit of capacity. The capacity of all these batteries were measured in Watt-Hours. Here are the numbers.\n\nAA Amazon Battery = 2.71 Wh. My cost per cell = $0.291. Cost per Watt-Hour = $0.107\nAA Duracell Procell = 3.09 Wh. My cost per cell = $0.321. Cost per Watt-Hour = $0.104\nAA Energizer Lithium = 4.86 Wh. My cost per cell = $1.27. Cost per Watt-Hour = $0.261\n\nThis test was done using an op-amp circuit to maintain a constant current load at 100ma. Voltage and current were being logged ounce per minute and this data was used to calculate the Amp-Hour with a 0.8 volt cutoff. The Watt-Hour was then calculated by multiplying the Amp-Hour by the average voltage from the beginning of the test to 0.8 volts. All batteries mentioned were tested using this same method. Note that the capacity of these batteries can change dramatically under different conditions. The same battery under a heavy load will have a fraction of the capacity that it would under a light load. This data is only good for a comparison when choosing what battery is worth buying at what price. Unless your device loads the battery at a constant current of 100ma.\n\nIn summery, the Amazon batteries are not bad batteries (at least based on this test using the AA cell). If you choose to shop around for a name brand battery, stay at or below $0.33 per cell. Anything above $0.33 per cell will be more expensive per unit capacity than the Amazon battery. Oh, and definitely stay away from the Energizer Lithium unless expense is not an issue. These batteries are only worth the additional cost if your application requires a light weight and relatively high capacity battery regardless of cost. These batteries are surprisingly light weight compared to an alkaline.lkaline."}, {'review_meta': 'Reviewed in the United States on December 4, 2017', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': "I've been buying AA and AAA batteries from Amazon Basics for a couple of years now. They recently changed the packaging (and presumably the manufacturer) and now they only last half as long. I tried a pair of Duracell AAs to test my hypothesis and they lasted almost three times as long. I wanted to stop buying these Amazon batteries, but it turns out that, at around $0.25 each and $0.90 for Duracell, they're still cheaper overall than buying name brand. However, it is extremely disappointing to watch them deliberately drop the quality and force us to purchase batteries more frequently. They've basically pulled a bait-and-switch with us, sucking us in with high quality batteries and then trading them out for lemons without dropping the price commensurately. Their packaging may be frustration-free, but these batteries sure aren't."}, {'review_meta': 'Reviewed in the United States on March 26, 2018', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': "Don't buy these. I did save a bunch of $'s, however once I started using them I have had at least 8 of them explode, leak and corrode. I use them in power blinds and had 2 of the battery cartridges for the blinds destroyed....costing $20 each to be replaced. Move on...don't purchase these. To late to get my money back because I wanted these on hand for when the originals failed, which started in Jan 2018.\n\n8 failures in 3 months once I started using them costing me over $40 to replace the damaged battery holders."}, {'review_meta': 'Reviewed in the United States on May 24, 2018', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': "I loved these batteries when I first started buying them. They were cheap and seemed to last. Then I bought 48! I figured - cheaper by the (4) dozen - Big mistake! Not only don't they hold a charge in a device, they are actually dead coming out of the shrink wrap. I actually had a couple literally fall apart in a camera. Luckily there was no damage. I expect high quality from Amazon basic products - they usually are great - but these batteries are terrible!."}, {'review_meta': 'Reviewed in the United States on December 12, 2017', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I use 10 to 15 AA and AAA Amazon batteries each and every month to power a range of professional electrical tools and meters that I must use for my work as a licensed electrician. I have never, repeat, never had the slightest problem with any of the Amazon batteries. I have never had so much as one leak acid or fail to properly fit. As an electrician, the first thing I do before putting any battery in a tool or meter is test its voltage. So far I have never had an Amazon that did not register either very strong or excellent before first use. Think this may be yet another case of folks who can't figure out how to use even the simplest thing giving up in frustration and giving whatever they don't understand a single star. Seems to happen all too often."}, {'review_meta': 'Reviewed in the United States on December 2, 2017', 'review_star': 'a-icon a-icon-star a-star-3 review-rating', 'review_body': "They work, absolutely! And they look really cute and come packaged well. But, they just don't last very long.\nFor example, I have two small strands of fairy lights that are battery dependent (pictured with AA battery for size comparison). Each strand needs 3 AA batteries. They have a timer allowing for 8 hours of use every day. When the ikeabrand batteries died (after being in use for 1 year), I replaced the batteries with these amazon basics batteries. The amazon basic batteries only lasted one month. That's an 11 month difference for the same amount of usage. Maybe I just got a bad batch. *shrugs* I am, and will always be, an amazon basics purchaser, but I'll go back to other battery brands once these run out. (which won't take too long at this rate.)"}, {'review_meta': 'Reviewed in the United States on September 26, 2017', 'review_star': 'a-icon a-icon-star a-star-3 review-rating', 'review_body': "I use these at church for wireless microphones. We had previously used the standard Duracell brand batteries, and would generally get 3-4 weeks (about 2 hours per week) out of them before they needed to be replaced. These only seem to last about 2 weeks at best. We'll be switching back to Duracell for this application.\n\nI would certainly use these for applications around the house... toys, remotes, keyboard/mouse, etc, but we need to make sure our batteries don't die in the middle of a church service, so we'll still to the good ones for our application."}, {'review_meta': 'Reviewed in the United States on December 11, 2016', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': 'I read a lot of reviews and convinced myself the AmazonBasics AA alkaline batteries were going to be a good buy. Nope. I put a pair in my TV remote, and within a month the TV was telling me to replace the batteries because of low power. I decided to check some new ones right out of the wrapper with my battery tester. 8 brand new batteries tested - all 8 in the red on the battery tester...not totally dead, but just inside the red. Next trip to Home Depot, I picked up the big pack of Energizer AA batteries and did the same test on them. 8 for 8 all in the green on my battery tester.\n\nOh well, not worth crying about $13 worth of weak batteries. I am sure others have had great luck with the same AmazonBasics AA batteries. I just wanted to add my experience so others can make an informed decision. Good luck!'}, {'review_meta': 'Reviewed in the United States on September 7, 2018', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': "I was aware that AmazonBasics batteries would not be as durable as more costly batteries and I have used these in various devices over the last year.. However, I did not expect a leak which damaged a remote control blind valued at $1000. The AA battery was one of 36 required to power 3 large Hunter Douglas fabric blinds. Less than 2 weeks after the annual battery replacement, I found that a black liquid was oozing from one of the battery holders, downward onto the blind, visible from both inside and from the patio outside. I removed all 12 batteries which were all dripping the liquid (acid??). We don't know yet if any of this can be professionally cleaned and at what cost. Worse yet, the mess permanently dulled a large granite island nearby while cleaning the batteries and my hands. The Amazon chat representative approved a refund for defective batteries and a $50 policy credit. Conclusion: these are very inexpensive, low to medium quality batteries. Do not use them for any purpose or devices where leaks would be a concern."}, {'review_meta': 'Reviewed in the United States on March 10, 2020', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': '(Note: Images attached show 2, unused AA batteries being tested - the Duracell is older than the Amazon Basics but still has a full charge, the Amazon Basics AA (only several months old and unused) is completely dead. Both were kept in the same storage).\n\nI bought this large pack of 48 AA batteries only several months ago and have been using them 2 at a time in a light fixture but I noticed something: That each time I replaced them, the lights wouldn\'t last as long as the same, Amazon Basics batteries I had put in before... turns out they had been slowly dying while they were in storage, not even being used!\n\nAt first I thought this was due to a faulty light fixture actually so to test it, I used some old Duracell batteries that I had and then after that, some old Energizer batteries - both of these lasted ~2-3 times longer than the Amazon Basic batteries. Finally I got a tester and tested the remaining batteries in storage - that I hadn\'t even used yet - aaannnnd about half of the Amazon Basics AA\'s had ~half a charge and the rest were completely dead... WITHOUT EVER USING THEM! My other AA batteries that were in the same storage (Duracell, Energizer and one "Player" brand) are even older but they still have a full charge!\n\nIn summary: These can\'t be stored for more than a few months and even the starting charge lasts only about half as long as other name-brands. If you\'re looking for good AA batteries, look elsewhere. I definitely won\'t be ordering these again.\n\nHope this is helpful to someone else out there.'}]
