Bests & Worsts Reviews from Amazon

I couldn't find a review stating the tested capacity of the leading AAA batteries on Amazon, so I took it upon myself to find out. For each of the 6 types I've tested (ACDelco, AmazonBasics, Duracell Coppertop, Duracell Procell, Energizer, and Rayovac), I discharged 3 batteries in my Opus BT-C2000 battery analyzer at rates of 100 ma, 200 ma, and 400 ma (discharge rate affects usable capacity). These ACDelco batteries were among the top in capacity, and stomped EVERY other battery in terms of value, with AmazonBasics as a runner-up. The capacity at each discharge rate was: Disch Rt | Capacity | Runtime | Sample use case 100 mA | 1005 mAh | 10.1 hrs | Low-power LED flashlight 200 mA | 864 mAh | 4.3 hrs | Electronic toy / medium LED flashlight 400 mA | 670 mAh | 1.7 hrs | Motorized toy / bright LED flashlight I ran the ACDelco batteries first, and my original review I stated that "Though not top-notch, these results are perfectly respectable". Well, since then I've run 5 more brands, and these are pretty close to top-notch. The only other brand that managed to beat them in ANY category was AmazonBasics, but really AmazonBasics and ACDelco were at the top of the stack and the differences were probably within the margin of error. Put simply: these batteries pack a lot of punch, and they're cheap. For the cost (~$10 as of this writing), these are an excellent value -- the power supplied per dollar spent is nearly unbeatable for a non-rechargeable aaa battery, AND the capacity is very nearly the best I've tested. I have not tested shelf life or leak resistance for any of the batteries in my roundup, so it's possible that some of the other batteries may do better in that regard. The one thing I *have* learned is that a battery's marketing has nothing to do with its actual performance for power capacity ... assuming that the same is true for storage, you'll have to wait until somebody runs a thorough leak and storage test to know which brand is best. I have posted reviews for Duracell Procell, Duracell Coppertop, Energizer, and AmazonBasics aaa alkaline batteries with capacity data gathered using the exact same method and equipment. I have attached a graph and table summarizing the results in the images.
