In short: Have a high opinion of Amazon but these batteries are a GENUINELY HORRIBLE value due to very low capacity.

This isn't opinion, we installed these same day they came (out of AAA's) and these batteries exhibited a very short lifespan (Duracell's last much longer in the same applications). So I checked the capacity rating on the battery and THERE ISN'T ONE. This is a bad sign, could not remember ever checking any small alkaline cell (AAA, AA, C, or D) that did not have the capacity rating printed on the battery.

So I tested three of these AmazonBasics cells (we have an accurate capacity tester to test R/C racing batteries). The three tested out at 252, 244, and a whopping 211mAh. Your average alkaline AAA battery will test out at around 700mAh capacity. So the AmazonBasics AAA cells (at least the ones I received and tested the next day) are junk.

Could be a bad batch, but is it worth it to buy batteries that may arrive near dead?

Dear Amazon Shopper,

I am no scientist. I don't know much about the fundamental mechanics of batteries, nor do I know what, chemically, differentiates a good battery from a great one. I do know, however, that what I want (and what most of you probably want) is the best value I can get for my money. On that subject, I have the following to say:

These batteries are significantly less-expensive, per-unit, than their name-brand counterparts. In order to get, for example, Duracell batteries at the same per-battery cost, you would have to buy a package of 100, which I suspect most people would be hard pressed to burn through before the batteries decline. If you subscribe-and-save for the Amazon Basics batteries, cost parity becomes virtually unattainable.

Depending upon the quantity and brand of battery you're looking at, the big names are anywhere from 17% to 80% more expensive than these batteries (those percentages increase when subscribe-and-save comes into play - note that I have not seen any non-amazon batteries that are S&S eligible, otherwise this factor would be irrelevant). In light of this, the question becomes not whether these Amazon batteries last as long as the big-name batteries, but whether the big name batteries last between 17% and 80% longer.

Since my physical chemistry is a bit rusty and I'm fresh out of lab-coats, I haven't exactly conducted any side-by-side tests. From a purely subjective standpoint, I don't notice that these Amazon batteries deplete any more or less quickly than their name-brand counterparts. That being said, IF name-brand batteries DO last longer (which I couldn't say), they would be more toward the 17% end of the spectrum than the 80%.

My conclusion, then, would be that if you can find a name-brand battery that lasts 70 days where an Amazon battery under the same conditions would last only 60 days, it's worth shelling out an extra 17%. My sense is that the disparity is not that great, meaning that the Amazon batteries are likely a better value. If you S&S at 5%, I'd definitively give the Amazon batteries the nod, and at 15%, it's not even a question. There are, however, a few intangible factors to consider:

1. IF the Amazon batteries do not last as long, you will be inconvenienced with having to change them more frequently, which can be irksome.

2. IF the Amazon batteries do not last as long, the environment takes yet another one for the team, as expended batteries piling up in landfills (you can throw them in the trash anywhere in the US except for CA) don't benefit anyone.

3. The packaging on the Amazon batteries is, to my mind, superior. Some simple, recyclable cardboard with two separately-contained rows of batteries. No tearing open the back of a part-plastic container, and no worrying about batteries spilling out of the packaging. The compact, nondescript frustration-free packaging is also easy to toss into a drawer or let sit innocuously on a shelf.

And that, my friends, is the long and short of it. It seems to me that these batteries are the best value to be had, particularly if you S&S, but I can't say that with 5-star certainty as I'm not sophisticated enough to really hone in on their comparative efficacy when measured against big-name batteries.

Thank you.

I ordered these batteries primarily to use in LED flashlights. I tried them in multiple flashlights of different brands and styles and all they did were flicker a bit. The old batteries I was replacing worked better than these so called new ones. I'm not sure what the problem is, none of the batteries in the package worked. I've never had this happen with any other battery at any price or brand. AmazonBasics Batteries are absolutely the worse batteries that I've ever used. Don't waste your money on these!!!

Bought these two years ago. The ones I had not used will not last a second in a bubble machine. I tried energizer cells that powered it with no problems. This seems like proof that these will not last on the shelf more than a year.I definitely would not use these for a low power device such as a remote control or rely on them for emergency flashlights.

Amazon has gone into the battery business! These batteries are a great alternative to the more expensive name brands. And so far, the quality seems just as good. The price is great and it's even better if you use "Subscribe and Save". Also, they came in a nice box ("frustration-free" packaging) which fits just perfectly in my drawer (I just cut off the lid). It kept the batteries from rolling around in the drawer.

And, really, who doesn't want that famous Amazon smiley on their batteries?? lol

Received in frustration-free packaging which is a godsend. Recommended for low draw applications.

TESTS:
Tested battery capacity at 0.1A and 0.5A. Batteries were discharged to 0.8V.

At 0.1A draw (very low discharge rate, akin to remote control), these batteries scored a very respectable 902mAh capacity. In addition, there was very little voltage droop until ~1/4 capacity, meaning that more power is delivered.

At 0.5A draw (stronger led flashlight draw), I found these batteries to have a 413mAh capacity. There is substantially higher voltage droop at this draw (down to 1.15V almost immediately).

For those that don't know, these are comparable values to more the basic (but more expensive) Duracell and Energizer batteries. Certainly not lithium energy density, but at ~900mAh, these batteries are a very good value. Don't hesitate to buy these for low power situations like remote controls, bluetooth mice, or low end flashlights. For high power draw devices, I could also recommend these batteries, but it would be a much better idea to move to either a rechargeable AAA (such as Eneloop), or a lithium based AAA battery which can commonly deliver >3x this capacity.

Amazon is my vendor of choice due to accurate shipping information,
competitive pricing, free shipping (most of the time), and quality products.
Just over three months ago I purchase some of the Amazon Basics AA and
AAA batteries. I am extremely disappointed with the performance of the
these batteries. I have used them in remotes for a computer mouse, and
TV remotes. In both cases the batteries lasted not in months but rather in a
couple of weeks.

I have never really noticed the difference in lasting power from one battery to another. Really. Is a $1 battery that much worse than a $2 batter? I've been on this Earth a long time and I've bought a lot of batteries in that time and I can now tell you that buying the cheapest batteries money can buy will cost you more in the long run.

These Amazon batteries have got to be the fastest-dying batteries I have every bought.

I have an electrical deadbolt on my doors that are battery powered and the battery pack usually lasts 6 months with normal standard alkaline batteries. With Amazon batteries I have to replace them every 60 days. I have an electrical lock on my mailbox and those batteries last a year. With Amazon batteries again they died after 60 days. I've gone through a pack of 20 in less than 4 months that should have lasted me 2 years.

Stay away from these batteries. It's cheaper to pay more.

These batteries do not last nearly as long as the name brand competitors. Not worth it even for the price. We go through them so quickly.

These AAA alkaline batteries are just what the weather stations ordered. I just added a 3 sensor weather station to the house and along with the main unit it requires 10 AAA batteries (not included) to make it operate. And by golly, it works and works perfectly because of its well made components and its ability to send signals back and forth with a full set of fresh batteries. Based on prior experiences with AmazonBasics batteries I feel certain I will be delighted with the quality and longevity of these. I chose these over a lithium battery because of cost per battery. The cost per battery for these is significantly less than the same lithium ion battery I had to go with them and have no regrets. Great quality and super cost.
