We have already tested both the 1.5V AAA Duracell Alkaline batteries and the 1.5V AAA Duracell Procell Alkaline batteries and they both did perform really well by providing very high capacities for AAA-sized Alkaline batteries. Since there is a common belief that the Duracell Copper Top Alkaline batteries are actually the same as the Duracell Procell Alkaline we are going to compare both types and see if they are indeed the same batteries with different labels or there is an actual difference as Duracell claims in favor of the Procell batteries.
You can see that at low current drain the difference is about 7% at 0.1A in favor of the Procell, however as the current draw increases to 0.2A the gap decreases a bit to just about 2.5%. Though at the at 0.3A load the Procell batteries take significant lead with close to 14% and by and going to 0.5A the difference in useable capacity you get gets even higher with about 35% in favor of the Procell batteries. So the 1.5V AAA Duracell Procell Alkaline batteries are actually better than the 1.5V AAA Duracell Copper Top Alkaline batteries especially when the load on the batteries gets higher, meaning that we are talking about different batteries indeed.
Duracell – Copper Top – Procell
0.1A load – 970 mAh – 1038 mAh
0.2A load – 777 mAh – 797 mAh
0.3A load – 553 mAh – 627 mAh
0.5A load – 336 mAh – 455 mAh
So in the end if you are going to be using AAA batteries in a low load applications such as a remote control for a TV for example, then you might just go with the standard Duracell Alkaline batteries as the difference in capacity in such situations is probably something that you will not notice at all… unless you manage to find Procells at a better price than the standard Duracell Copper Tops. For applications that require more power however such as remote controlled toys for example you should consider choosing the Procells as they will definitely be able to offer you significantly more.

1.5V AAA Duracell Alkaline Battery Tests
31, Aug 2013
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
On the internet there is a lot of talk about the standard Duracell Copper Top Alkaline batteries and the Duracell Procell Alkaline batteries intended for business and industrial use. You can find some claims that both are essentially the same battery, just with different packaging, however since we’ve tested both types of these we can confirm that there is slight difference between them. The Duracell Procell Alkaline batteries are indeed a bit better by providing a bit more capacity under the same conditions, so they are not the same as the standard Copper Top batteries that the company offers to consumers.
You can see that at low current drain the difference is just about 9% at 0.1A in favor of the Procell model, however as the current draw increases the gap continues to increase and the Procell batteries are able to deliver more – 15% at 0.2A, 18.5% at 0.5A and going to 1A the difference in useable capacity you get goes to a bit more than 17%. So the 1.5V AA Duracell Copper Top Alkaline batteries are clearly not as good as their Procell counterparts…
Duracell – Copper Top – Procell
0.1A load – 2348 mAh – 2557 mAh
0.2A load – 1808 mAh – 2120 mAh
0.5A load – 1050 mAh – 1287 mAh
1.0A load – 506 mAh – 619 mAh
In the end if you can get Duracell Procell and you really need the better capacity they provide along with the supposedly better performance in more extreme operating conditions (we still need to check that as well) and they do not come at a significantly higher price compared to the standard Duracell Copper Top Alkaline batteries you should go for the Procell ones.
