9V Duracel Copper Top vs Duracell Procell Alkaline Batteries

9v-duracell-copper-top-vs-procell-alkaline-battery

We have already tested both the 9V Duracell Alkaline batteries and the 9V Duracell Procell Alkaline batteries and we’ve seen interesting results, we’ve decided to do a direct comparison between the two since there is a common belief that the Duracell Copper Top Alkaline batteries are actually the same as the Duracell Procell Alkaline. If the two types of batteries are exactly the same they should be able to provide very similar useable capacity in our tests, however this is not the case as you will see in a moment. In order to make sure that we are properly comparing the two types of batteries we got them with matching expiration dates just to be sure that there should be no significant difference due to self discharge if they were produced in bigger time difference.

So far our comparisons between Duracell Copper Top and Duracell Procell batteries have shown slight advantage in favor of the Procells for the AA and AAA size, so this time we kind of expected to get similar results, but to our surprise we did not. In fact the standard Copper Top Duracell battery did provide better result and with over 20% higher useable capacity than the Procell this is a significant different. We did check the expiration dates to match and have repeated the test with another 9V Duracell Procell battery just to be sure there was nothing wrong, but we got pretty much the same lower capacity from the Procell. In the end we can say that we were really disappointed from the 9V Duracell Procell batteries, we expected to see more from them, especially considering the fact that around 300 mAh is what a decent 9V Alkaline battery should be able to provide in our test conditions.

Duracell – Copper Top – Procell
0.05A load – 311 mAh – 245 mAh

With these results there is no way to recommend the Procell over the standard Copper Top model when talking about 9V Alkaline batteries from Duracell, though that is not the case with AA and AAA size Duracell batteries where we’ve seen very good performance from both Copper Top and Procell Duracell batteries. In fact when talking about 9V Alkaline batteries we are not going to recommend you to go for a Duracell at all, regardless if Copper Top or Procell as we have already tested other brands that are capable of giving you close to 50% more capacity than what Duracell does… and at a price that can be lower than that of Duracell!

That is very odd, I always thought that the ProCell was better too. That is why I try to stay away from 9V devices. The batteries have a very poor performance (except the lithium ones of course) and pretty much the same Wh capacity as a single AA cell. I will never purchase Duracell 9V batteries again. Thank you for the hard work put into these tests. 😀

I think I spoke to soon because the Duracell Copper Top that is shown in the picture might be a fake one. On mine says Duralock and the copper color is not the same color tone and on the back has lots of writings. Also on mine says that it’s Made in the U.S.A. I do not buy Duracell batteries from the stores near me because even the AAA ones cost about 0.61$ and the AA 0.77 bucks a piece. On top of that pretty much 50% of them are fake ones. I bought some AAA’s a few months ago and when I tried to use them a few days ago, the voltage would sag too much. No matter if you short the darn thing for 10 minutes. The voltage across the terminals would still read at least 1.2V. Which is clearly because of the high internal resistance. I also found some interesting pictures
of some fake ones. Mine was clearly a fake one. So yeah top prices and very low quality. So please make sure you verify that the cells you test are genuine otherwise you will get disappointing results. Also on my ProCell says that it’s Made in Malaysia.

Both Duracell batteries compared here are made in Malaysia and are originals, not a fake ones. It is possible that Duracell has different production facilities for USA and Europe (these are bought in Europe), it is more reasonable to import batteries from Asia to Europe than from USA 🙂

I think you’re right. I’ve got some Procell AA’s and AAA’s and they’re made in Belgium. I guess they are importing them from whichever country is closer. But I think that there might be some variations in quality. Like for example WD-40, I just cannot find anywhere an original U.S.A or Australia made one. And I think they are better.

As a muscian, I use Duracell AA, AAA, and 9V batteries aplenty, and of course always looking for a better deals. The article above indicates ” In fact when talking about 9V Alkaline batteries we are not going to recommend you to go for a Duracell at all, regardless if Copper Top or Procell as we have already tested other brands that are capable of giving you close to 50% more capacity than what Duracell does… and at a price that can be lower than that of Duracell!”
I have been a loyal Duracell person for years, but better performance is what drives loyalty. So, can you post/show data and/or brand names for the “other brands”?
