9v-fujicell-alkaline-battery

The 9V Fujicell Alkaline batteries we are testing here are proving to be interesting as we’ve seen from tests of other Fujicell batteries where they are performing quite well and considering the fact that these batteries are available at a good price you may want to consider the good models. The question here is how will the 9V Alkaline battery perform and will it be worth to consider. The battery we are testing is with an expiration date of 02-2020.


9v-fujicell-alkaline-battery-capacity

In order to test the capacity of the 9V Fujicell Alkaline batteries we are using a constant current discharge rate of 0.05A (50 miliampers) and we have managed to get 398 mAh and that is a very good results for a 9V Alkaline battery. If we compare this to the 9v Duracell Alkaline battery that we are using as a reference the Fujicell battery offers significantly higher capacity at a more affordable price, so definitely a good choice if you are in need of a 9V Alkaline battery.

The performance of the 9V Fujicell Alkaline batteries in our tests:

– 398 mAh at 0.05A load

– 2.954 Wh at 0.05A load

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

1-5v-aa-xcell-alkaline-battery

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.


1-5v-aa-xcell-alkaline-battery-capacity

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
