9v-duracell-procell-alkaline-battery

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.


9v-duracell-procell-alkaline-battery-capacity

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

The 1.5V AA Xcell Alkaline batteries don’t seem as something special, but we’ve decided to give them a try and see how good will they be able to perform in our tests. The batteries we’ve used for testing were with an expiration date of just the year 2017, no specific month, so they should be with either 4 or 5 years of shelf life.

Starting our test of the 1.5V AA Xcell Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 2063 mAh as capacity. With that capacity they do not manage to get into our top 10 of best AA-size Alkaline batteries, though the level of capacity they offer is still more than decent if the price is right. Increasing the level of constant current load that we are testing with to 0.2A we still get a decent useable capacity, but past that the performance gets even worse, so better not use these batteries for higher power drain applications.

The performance of the 1.5V AA Xcell Alkaline batteries in our tests:

– 2063 mAh at 0.1A load
– 1586 mAh at 0.2A load
– 761 mAh at 0.5A load
– 267 mAh at 1.0A load

– 2.521 Wh at 0.1A load
– 1.858 Wh at 0.2A load
– 0.859 Wh at 0.5A load
– 0.293 Wh at 1.0A load

The 1.5V AAA Panasonic Pro Power Alkaline are supposed to offer premium energy for personal appliances and should be ideal for high and medium drain appliances according to Panasonic. They are almost the highest-end Alkaline batteries that the company offers, the only supposedly better option are the ones in the Evolta range. The Panasonic Pro Power Alkaline batteries we tested here were with an expiration date of 01-2018 meaning that they should be offering at least 5 years shelf life.

Starting our test as we usually do with a low constant current discharge rate of 0.1A we have managed to get 794 mAh as capacity from the 1.5V AAA Panasonic Pro Power Alkaline batteries, or a it disappointing result placing them more in the mid-range among the AAA size Alkaline batteries we have tested so far. At 0.2A and 0.3A constant current discharge rates the batteries still perform quite well, though at a level of 0.5A there is a more significant drop in the usable capacity you can get, meaning that these batteries are not going to be handling well in devices that have quite high power requirements and are using AAA-size batteries.

The performance of the 1.5V AAA Panasonic Pro Power Alkaline batteries in our tests:

– 794 mAh at 0.1A load
– 593 mAh at 0.2A load
– 492 mAh at 0.3A load
– 159 mAh at 0.5A load

– 0.964 Wh at 0.1A load
– 0.707 Wh at 0.2A load
– 0.568 Wh at 0.3A load
– 0.173 Wh at 0.5A load
