To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
AmazonBasics batteries are quite good in terms of capacity -- pretty much tied for the top spot compared to the other 6 brands I've tested, but other brands have the edge in capacity per dollar. When I computed value by dividing capacity by the cost per battery of the cheapest package size, they took a respectable third place, and they have the advantage of being a trusted name compared to the value leader. In the images I have attached a graph and a table summarizing my test results for the 7 types I've tested, but if you'd like to know more about how I test ... on to the in-dept test & review.
I've been on a bit of a quest to test all of the top-selling aaa batteries on Amazon in a repeatable, precise way. This means the same equipment, same environmental conditions, and same slots in the equipment will be used for each test. For each test, I fully discharge 3 batteries in my Opus BT-C2000 battery analyzer at rates of 100 ma, 200 ma, and 400 ma (discharge rate affects usable capacity). I have also performed this exact same test (same equipment, same conditions) on the ACDelco, Duracell Procell, Duracell Coppertop, Energizer MAX, Maxell, and Rayovac. I have linked the other brands I've reviewed at the end of this review if you'd like to take a look at the other results for comparison purposes. For the Amazon Basics batteries, the capacity at each discharge rate was:
Disch Rt | Capacity | Runtime | Sample use case 100 mA | 997 mAh | 10 hrs | Low-power LED flashlight 200 mA | 914 mAh | 4.5 hrs | Electronic toy / medium LED flashlight 400 mA | 623 mAh | 1.5 hrs | Motorized toy / bright LED flashlight
Note that these (and all other Alkalines) would achieve somewhat higher capacity (maybe 1200 mAh) in a low discharge application like a mouse, keyboard, remote control, etc because alkaline batteries have internal resistance that reduces usable capacity at high discharge rates.
The capacity of these batteries is among the best I've tested -- take a look at the attached data table for comparative data. For the cost (~$0.31/ea in a 36 pack right now), these are a decent but beatable value -- the power supplied per dollar spent is very good, but eclipsed by other currently available options.
These batteries do well capacity-wise, but value-wise are blown away by the currently cheapest energy/dollar battery that I've tested, the ACDelco aaa's. Their capacity results were:
Disch Rt | Capacity | Runtime 100 mA | 1005 mAh | 10 hrs 200 mA | 864 mAh | 4.3 hrs 400 mA | 670 mAh | 1.7 hrs
As you can see, the Amazon batteries were very comperable ... but, at the current time the AmazonBasics batteries are $0.31/ea (36 pack), while the ACDelco batteries are about $0.21/ea (48 pack) -- so the ACDelco are significantly cheaper per mAh. I did not test shelf life, so it's possible that these may hold up better sitting in a drawer. Although both the Amazon batteries and the ACDelco batteries are certainly made on contract by a third party, I do think that I trust Amazon a bit more to provide consistent batteries than ACDelco ... although I haven't had any trouble with my ACDelco batteries so far. It's also worth noting that the Amazon batteries come in clearly superior packaging - while the ACDelco batteries come in a horrible gigantic plastic blister pack, the Amazon batteries come in a closable cardboard box. If you don't go through a lot of batteries & organization of your battery drawer is important to you, that could push them into the all-around winner category despite the ~50% price premium.
Finally, because another review specifically mentions the Rayovac AA's as being 'good' in some usage scenarios, I thought I'd share my findings for the Rayovac AAA's. In short, they're garbage - the Amazon batteries are better in EVERY case. It's possible that the Rayovac AA's are much better than the AAA's, but I think it's more likely that the version of the Rayovacs tested by the website that he got his results from is different than the most popular Rayovac on Amazon (I source all of my batteries from Amazon). I ran the Rayovac test several times because I couldn't believe how poorly they did ... here are some typical Rayovac results:
Disch Rt | Capacity | Runtime 100 mA | 908 mAh | 9 hrs 200 mA | 590 mAh | 2.9 hrs 400 mA | 443 mAh | 1.1 hrs
My other battery tests/reviews:
I have posted reviews for Duracell Coppertop, Duracell Procell and ACDelco aaa alkaline batteries with capacity data gathered using the exact same method and equipment. To find those reviews for comparison purposes, go to the product pages linked below and search for 'mah' under 'all reviews' (or just browse to them on my profile). If/when I do additional aaa tests/reviews in the future, I will update this list.

Not only did a few batteries leak they ruined one of my Gideon Flameless LED candles. I am so disappointed. I thought that with the Amazon name I would have a quality product. I purchase many products from the Amazon website. I would like a refund and a replacement for the ruined Gideion Flameless LED candle. I purchased three candles and the 6 inch candle is ruined.
These were purchased for a banquet to illuminate lights in our centerpiece vases. I thought these would have had enough juice to get through the evening but more than half of the vases were failing an hour before the event conclusion. I was very disappointed and will not be buying these again. It's unfortunate that they are listed as "performance" batteries vs. some other descriptive name. I should have read the critical reviews more carefully and noted that these don't have as much power per cell as Rayovac or others. Strangely, we used very cheap no-name batteries last year for the same event that lasted the entire evening and then some. I couldn't remember where they came from so I had to look for substitutes. I thought I was making a good purchase with a trusted brand. Unfortunately, that assumption wasn't accurate.
Yes these are cheap, and perhaps that’s why they lasted about two years at most unused. I had a scale and the batteries died and when I went to replace them with the last unused batteries I had left from Amazon, the scale still didn’t work. So I thought the issue was the scale and threw it away. I bought a new scale and tried using batteries but that scale didn’t work either. So I purchased new batteries and the scale worked just fine. So the issue was that the batteries were dead. I regret I did not check that before I threw out my current scale. Poor Amazon branded product quality cost me the price of the new scale. Batteries are supposed to last longer than two years. I contacted Amazon customer service to see if they would make the situation right, but they only gave me a small promotional credit and did not stand behind the quality of their own products.
There’s nothing wrong with these batteries. They work fine. They’re cheap. They come with my monthly Amazon shipments.
No, unfortunately not. I have no idea why Amazon feels the need to overpackage these batteries so much. They come in sets of three, in cellophane wrappers that are impossible to tear with your hands. So you have to cut each set of three with a knife and if you bought any larger quantity of them (which you usually do using Subscribe and Save) it takes a long time to go through them all. Not to mention the unnecessary waste of all those pointless wrappers which are packaged inside a little corrugated cardboard box anyway, then put into another Amazon box with whatever else you ordered.
I’ve bought these in AA and AAA several times, but I’m done. I’ll spend a little more to get name brand batteries in packaging that doesn’t pss me off so much.
I have been trying to find batteries that will work well in a lantern. I have tried generic store brand, these AmazonBasics, Duracell, Energizer lithium etc. So far these work about as long as the generic store brand. The longest working are the Energizer lithium, but none last very long. I think the lantern should have used a different size battery. I am sure these will work fine for some things, just not what I needed them for.
I’ve purchased these for years and my last order of them died very fast. I had them in led string lights and they were on a timer- about two hours per day. They were dead within a week as opposed to buying them last year and they lasted three.
These at first seem like a good value based on price, but the longevity for the 20 pack I purchased is terrible. I bought these to replace batteries in a digital scale that used to last months with a big name brand battery. With these batteries, I’m replacing every few weeks with little usage. I won’t purchase these again.
Amazon brand batteries AAA’s does not work in Amazon fire stick remote I put brand new batteries Amazon brand And Remote won’t work , And then I bought a different brand batteries Duracell it was working completely fine
Thought this would be a good deal as the price is pretty reasonable. But I soon realized that I'm replacing batteries a lot more often then I ever have. I've had remotes that came with batteries included that look off brand and cheap, but then realized they lasted for years. Replaced some of those and now I'm changing the batteries every few months. So, yes they are cheap, but I guess there is a reason why they are. Will pay more next time for better batteries.
