Anti-Leakage Protection, Holds in Power for up to 10 years in storage under normal use. 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. Superior Performance: The AmazonBasics Performance Alkaline batteries perform as good or better than the top branded batteries on the market. The batteries are suited for both high and low drain devices. 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. Stays Connected: 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 / 70 degrees Celsius and high humidity of up to 90%. Power When You Need It: The Anode material reactivity is enhanced by a new zinc composition. The amount of additional elements for anti-corrosion was lowered by reducing impurities in the zinc leading to higher reactivity and more power. Increased Safety: The addition of a Short Circuit Preventive Washer (SPW) prevents leakage and heat built up in case of misuse to make the batteries safer. An Amazon Brand. string

10-Year Shelf Life: Emergency Ready
Holding power for up to 10 years while in storage, the well-built battery’s air- and liquid-tight seal securely contains the power until it’s needed. The battery locks in power and won’t leak thanks to its improved anti-corrosion components, new zinc composition, and two-crimp design.
A great choice when buying in bulk, the long-lasting AmazonBasics batteries can be used immediately or stored for reliable power later—perfect for weather radios, flashlights, and other must-haves in an emergency.
Made with quality components, the AmazonBasics battery provides safe operation for both the user and the device.
If misused or over-worked, the battery’s insulating ring—a short circuit preventive washer (SPW)—protects against short circuiting and self discharging, while two small holes prevent heat build-up and bursting. The battery offers both reliable safety and ultimate peace of mind.

I 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.
AA Amazon Battery = 2.71 Wh. My cost per cell = $0.291. Cost per Watt-Hour = $0.107
AA Duracell Procell = 3.09 Wh. My cost per cell = $0.321. Cost per Watt-Hour = $0.104
AA Energizer Lithium = 4.86 Wh. My cost per cell = $1.27. Cost per Watt-Hour = $0.261
This 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.
In 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.
8 failures in 3 months once I started using them costing me over $40 to replace the damaged battery holders.
Oh 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!
