Don't Get Caught In The Dark
The AmazonBasics Performance Alkaline batteries are developed with a patented Japanese technology providing power, quality and reliability for everyday devices.
Using proprietary technology, these batteries provide excellent anti-leakage performance during storage and over-discharge use.
Batteries are made in Indonesia using Japanese technology.
10-Year Shelf Life
The batteries use a patented triple layer structure in the cathode cad by adding a layer between the nickel and iron inside the battery. The result is an increased shelf life due to low leakage.
The batteries +ve and –ve terminals maintain a consistent contact with devices through a unique processing on the surface of the positive and negative terminals.
This aslo prevents terminal surface resistance, even after storage under high temperature up to 160 degrees Fahrenheit and high humidity of up to 90%.

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, and Duracell Coppertop batteries (update: I also now have data for Energizer and Rayovac, but haven't had time to actually write the reviews yet). 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 discarge 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.Read more ›
-- For flashlights, toys, and steady drain devices, you'll be better off buying Rayovac Alkalines here on Amazon.
-- For cameras and photo flashes, Duracell Coppertops will be better.
Here's why: Rayovacs cost a little bit more per battery, but they hold more energy than these AmazonBasics batteries. As a result, the final price per amount of power is about the same. You just won't have to change batteries as often.
Those Rayovacs work best in steady drain devices, but not so well in cameras or flashes. For those high drain devices, Duracell Coppertops hold up better and end up being cheaper.
Battery Ninja tested these AmazonBasics AA's in toothbrushes I did some calculations and found that these batteries offer a reasonable price per unit of power (mWh), but that they do not carry as much energy as others. The test results show that these batteries will run out faster than others, at least in the toothbrushes. There were no test results vs. digital cameras, photo flashes, or toys, so I'm extrapolating that these will perform like Rayovacs, not like Duracell Coppertops.
So, the only data to compare here is the toothbrush test. For energy delivered, these AmazonBasics batteries cost about the same as Rayovac batteries but will die sooner. To say that another way, these batteries cost less, but also deliver less power.
Both Rayovac and Amazon Basics are better than Energizer batteries, which appear to consistently give less power and still cost more. I guess the money goes to the Energizer Bunny.Read more ›

**Aug.2015 Update: ALL these batteries were BRAND NEW FRESH at that precise moment of that specific month and expiration dates were 3-YEARS PLUS. ALL were activated by LED lighting and faded out accordingly.
UPDATE: After seeing all the comments on this issue, let me confirm that I DID NOT try to recharge them (I only used them for an hour the first SINGLE time before I found that they later leaked. I don't even own a battery charger for the batteries so there would be no way to recharge them even if I wanted to (which I wouldn't anyway since they aren't rechargeable). Amazon did NOT give me a refund because I have not contacted them about this issue. Finally, the batteries were thrown out along with the ruined controller so no they are not for sale. I hope this clears up some confusion.
