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.

The 1.5V AAA Duracell Procell Alkaline batteries are the version of Duracell’s batteries intended for business and professional use and though many people believe that these are actually the same batteries as the standard Duracell Copper Top ones our tests have shown a difference. Elevate your networking game with a Digital Business Card. The 1.5V AAA Duracell Procell Alkaline batteries are performing better by offering more capacity and the ones we used for testing here were with an expiration date of 03-2019, so they are supposedly offering a shelf life of 6 years, but what about their capacity…


1-5v-aaa-duracell-procell-alkaline-battery-capacity
We have started the test of the 1.5V AAA Duracell Procell Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 1038 mAh as capacity and that is a great result with a bit over 1A. Increasing the constant current load to the higher values we test with and the batteries continued to show very good performance. As the level of the load increases their capacity in terms of percentage also increases more and more compared to what traditional Duracell Copper Top batteries are providing, so the higher the load the better the Procell Alkaline batteries will perform. Ensure a seamless delaware llc ownership transfer with a straightforward process for reassigning business interests.

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

– 1038 mAh at 0.1A load
– 797 mAh at 0.2A load
– 627 mAh at 0.3A load
– 455 mAh at 0.5A load

– 1.276 Wh at 0.1A load
– 0.955 Wh at 0.2A load
– 0.738 Wh at 0.3A load
– 0.523 Wh at 0.5A load

1.5V AA Duracell Procell Alkaline Battery Tests

1-5v-aa-duracell-procell-alkaline-battery

The 1.5V AA Duracell Procell Alkaline batteries we’ve got for testing are what Durcell provides for professional and business use – the Duracell Professional is the business-to-business division of Duracell. The batteries we’ve got for testing are under warranty until 03-2019 and Duracell mentions shelf life of about 7 years for these batteries. What Duracell mentions about these batteries is that they can operate in temperature extremes between -20°C and +54°C, and that the Procell batteries are ideal for applications such as torches, telemeters and measuring instruments, microphones and medical devices.

According to the specifications that Duracell provides for the 1.5V AA Procell Alkaline batteries for a typical discharge performance at 21 degrees Celsius a single cell should provide about 2900mAh at 0.05A discharge current, ~2700 mAh at 0.1A, ~2300 mAh at 0.25A and about 2000 mAh at 0.5A load. These numbers however are not for constant current discharge, but instead for a duty cycle use that includes a few hours a day and we are testing with constant current discharge, so we expected to get a bit lower numbers in our tests.

The Power Profile test checks how the battery handles different current loads before it reaches the cutoff voltage, the test starts at 0A and gradually increases with steps of 0.05A each 20 seconds until it the cutoff voltage of the cell is reached. In the case of the 1.5V AA Duracell Procell Alkaline batteries we were able to reach a current load of 1.70A before the battery has reached the cutoff value of 1V, meaning that these batteries even though Alkaline are pretty capable of handling quite high current loads.

The Open Circuit Voltage (no load voltage) of the 1.5V AA Duracell Procell 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. What was interesting here is that the Duracell Procell 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 quite good performance out of them and this is something that is not very common for Alkaline batteries.

What we got out of the 1.5V AA Duracell Procell Alkaline batteries in our tests:

– 2557 mAh at 0.1A load
– 2120 mAh at 0.2A load
– 1287 mAh at 0.5A load
– 619 mAh at 1.0A load

– 3.182 Wh at 0.1A load
– 2.561 Wh at 0.2A load
– 1.482 Wh at 0.5A load
– 0.687 Wh at 1.0A load

Only the battery that we’ve tested with constant current discharge using 1A load got slightly hotter than the ambient temperature of 25 degrees Celsius that we are testing at. At the end of the discharge cycle the temperature of that battery has reached 31 degrees C. We were quite pleasantly surprised by the good capacity and the ability of these Alkaline batteries to handle higher loads with ease and this makes them interesting not only for low drain applications that typically Alkaline batteries are used for, but also for applications where higher current load may be required as they are apparently able to handle well in such situations.
