Tests and reviews of different batteries to help you find the Right One…
The 9V Duracell Procell Alkaline batteries we are testing here are from the Professional series of Duracell, a series that has lot of controversy surround it regarding if these are the same batteries or not as the standard Duracell Copper Top batteries. We’ve already tested AA and AAA size Copper Tops and Procells with the same expiration date and compared them to reveal that the Procell batteries do perform a bit better, so we are expecting to see something similar with the 9V Procell batteries by Duracell as well and we are of course going to compare them to the 9V copper Tops that we have already tested here. The expiration date of the battery tested here is 03-2017, something that is very important to note when doing battery comparisons as while Alkaline batteries do self discharge pretty slow over time as compared to NiMHs for example they still do.
In order to test the capacity of the 9V Duracell Procell Alkaline batteries we are using a constant current discharge rate of 0.05A (50 miliampers) and we have managed to get 245 mAh and that is quite Ok for a 9V Alkaline battery, though we must say we kind of expected to see better performance out of these Duracell batteries. So in order to be sure we have picked up a second Procell battery and it got us 242 mAh under the same conditions, a bit of a disappointment considering the fact that we have managed to get better results out of a 9V Duracell Copper Top battery.
The performance of the 9V Duracell Procell Alkaline batteries in our tests:
– 245 mAh at 0.05A load
– 1.812 Wh at 0.05A load
