The 1.5V AAA Duracell Alkaline batteries are our reference batteries for comparing how other brands’ AAA batteries are performing, because as we know the Duracell Copper Top are performing very well, though they may not be the ones offering the highest capacity in various conditions. The 1.5V AAA Duracell Alkaline batteries we used for testing here were with an expiration date of 03-2019, so they are supposedly offering a long shelf life of 6 years, but what about the capacity they can provide…

We have started the test of the 1.5V AAA Duracell Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 970 mAh as capacity and that is a very good result close to 1A. Increasing the constant current load to the higher values we use for testing the batteries continued to show very good performance and even in high loads they’ve managed to offer good performance. So it will be interesting to see how good other AAA size Alkaline batteries will compare in terms of capacity in our tests.

The performance of the 1.5V AAA Duracell Alkaline Batteries in our tests:

– 970 mAh at 0.1A load
– 777 mAh at 0.2A load
– 553 mAh at 0.3A load
– 336 mAh at 0.5A load

– 1.174 Wh at 0.1A load
– 0.916 Wh at 0.2A load
– 0.637 Wh at 0.3A load
– 0.378 Wh at 0.5A load
