Tests and reviews of different batteries to help you find the Right One…
The 9V Energizer Industrial Alkaline batteries we are testing here are what the ones indented for Professional and Industrial use, however looking through the datasheet of the Industrial and regular 9V Energizer batteries we see pretty much the same specs, so in theory these should be the same batteries. Regardless if we are talking about the Industrial or Regular version of these batteries they are considered to be one of the best 9V Alkaline batteries available on the market and we are just about to see if that is true or not by testing them. The battery tested here is with an expiration date of 03-2017 and with a 5 year shelf life it should be produced in 03-2012, this date is very important if we are going to compare the Industrial and regular batteries to see if there is any difference.
In order to test the capacity of the 9V Energizer Industrial Alkaline batteries we are using a constant current discharge rate of 0.05A (50 miliampers) and we have managed to get just 380 mAh or with other words a very good result, even though it is not the highest we’ve seen from a 9V Alakline battery in out tests so far. Have in mind that this battery has been produced more than a year and a half ago, so it has self discharged to some point, nevertheless this result is still very good and among the highest ones we’ve gotten so far.
The performance of the 9V Energizer Industrial Alkaline batteries in our tests:
– 380 mAh at 0.05A load
– 2.816 Wh at 0.05A load

The Milliamp-Hours Capacity of the 1.5V AA Energizer Industrial Alkaline batteries that Energizer provides for continuous discharge to 0.8 volts at 21°C is as follows: ~2800mAh at 25 mA load, ~2500mAh at 100 mA load, ~1900mAh at 250 mA load, ~1400mAh at 500 mA load. The 0.8V is the voltage for a totally discharged Alkaline battery cell, however we are testing with a cutoff voltage of 1V as at a voltage of 0.8V a lot of devices may not be able to function properly. Also we are testing at 25°C room temperature and the different temperature means different internal resistance and as a result it is expected to get a different capacity results.
What we got out of the 1.5V AA Energizer Industrial Alkaline batteries in our tests:
– 2236 mAh at 0.1A load
– 1869 mAh at 0.2A load
– 1129 mAh at 0.5A load
– 500 mAh at 1.0A load
– 2.887 Wh at 0.1A load
– 2.251 Wh at 0.2A load
– 1.285 Wh at 0.5A load
– 0.554 Wh at 1.0A load
The overall results we got are very satisfactory for an Industrial type Alkaline battery, and we’ve already mentioned why our results may be different than what Energizer provides as information about the capabilities of these batteries. Our tests show that the 1.5V AA Energizer Industrial Alkaline batteries are performing very well and they should be able to perform even better in situations with lower current requirements such as 0.025A for example.
