1.5V AAA Duracel Copper Top vs Duracell Procell Alkaline Batteries

2 Sep


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.
