Tests and reviews of different batteries to help you find the Right One…
The 1.5V AA Duracell Alkaline batteries we are testing are the typical Duracell Copper Top batteries that you can find pretty much everywhere in a shop or a gas station. The batteries we’ve got for testing are under warranty until 03-2019 and Duracell mentions that these are guaranteed for 10 years in storage. Duracell’s website does not have detailed information about the specs of these batteries or the capacity they are supposed to offer, so we’ve decided to test them so that yo will be able to compare the results to other Alkaline batteries.
The Open Circuit Voltage (no load voltage) of the 1.5V AA Duracell Alkaline batteries is 1.6V, though it quickly drops to 1.5V under load. We are testing all Alkaline batteries with a constant current load of 0.1A, 0.2A, 0.5A and 1A and measuring what capacity they can provide at these levels, and these Alkaline cells from Duracell are no exception. The Duracell batteries are able to handle quite well higher current drain for a while and although there is an expected drop in the useable capacity you get even at 1A constant current load we got a decent performance out of them.
What we got out of the 1.5V AA Duracell Alkaline batteries in our tests:
– 2348 mAh at 0.1A load
– 1808 mAh at 0.2A load
– 1050 mAh at 0.5A load
– 506 mAh at 1.0A load
– 2.913 Wh at 0.1A load
– 2.189 Wh at 0.2A load
– 1.194 Wh at 0.5A load
– 0.564 Wh at 1.0A load
