The industrial by Duracell batteries are designed and packaged for wholesale and professional trade customers and are providing high quantities of dependable batteries at a cost-effective price according to Duracell. They are supposed to be delivering long-lasting power across a range of professional applications, capable of operating in temperatures from -20°C to 54°C and offer reliable performance, even after seven years of storage. So you should not be expecting the highest performance out of these and you should also be careful when picking up a larger quantity that the batteries are from a fresher batch. The one we received and are going to be testing here is with an expiration date March 2022, so not the freshest one out there if it has a 7 year life, but even with 5 years we still get only 3 more years, so again be careful with that.


Our test of the 9V Duracell Industrial Alkaline battery are at a constant current discharge rate of 0.05A (50 milliamps) and we have managed to get 347 mAh usable capacity in the test. That result puts it around the middle of the results we ave seen so far in our 9V alkaline battery tests, though a fresher battery should be able to get you some more capacity… most likely as the storage conditions are also important and not just the remaining shelf life for an alkaline battery. Our tests of other Industrial alkaline batteries are showing that they are usually around the mid-range of usable capacity compared to other regular alkaline batteries.

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

– 347 mAh at 0.05A load

– 2.562 Wh at 0.05A load

We have picked up a pack of fresh 1.5V AAA Sony Alkaline Blue (AM4L-B4D) batteries to test and see how well will they perform. The batteries are produced in 01-2019 and Sony claims that these are longer lasting batteries that can keep power for up to 8 years (expiration date 01-2027) if properly stored at ambient temperature between 18 and 22 degrees Celsius. Of course most people do not care much for their batteries and will probably not try to extend their live, especially for cheaper alkaline batteries like these, so hardly they will be kept under optimal conditions. With alkaline batteries you usually pick a pack and put them right to some use in a device, so just make sure you get a freshly produced cells.


The 1.5V AAA Sony Alkaline Blue batteries do manage to show good results in our tests with capacity above average (closer to the top performers in the AAA alkaline category) and better than what we have got a couple of years ago from Sony Stamina Plus AAA batteries. We are getting high usable capacities for 0.1A, 0.2A and 0.3A constant current loads and going for the higher 0.5A discharge test we see a more significant drop in the usable capacity. The longer 8 year shelf life of the batteries is also a plus, compared to the regular 5 years that most alkaline batteries normally get.

The performance of the 1.5V AAA Sony Alkaline Blue batteries in our tests:

– 910 mAh at 0.1A load
– 784 mAh at 0.2A load
– 609 mAh at 0.3A load
– 324 mAh at 0.5A load

– 1.101 Wh at 0.1A load
– 0.926 Wh at 0.2A load
– 0.692 Wh at 0.3A load
– 0.362 Wh at 0.5A load

Time for another tests of 1.5V IKEA Alkalisk alkaline batteries, this time a pack of AA sized batteries with a fresh production date that we especially check when picking up the 10-battery pack from the store (after getting AAA IKEA alkaline batteries with old production date recently). The production date of these affordably priced batteries from IKEA is 07-12-2018 and the expiration date is 2023, so a 5 year warranty and pretty fresh batch of batteries at a good price in 10-pack box, but let us see what we can expect from them in terms of usable capacity in our tests…


The 1.5V AA IKEA Alkalisk Alkaline batteries are performing quite well in our tests all the way up to the 0.5A constant current load, after which the usable capacity shows a larger drop. The capacity levels are above average for these IEKA batteries, but are far from the top performers in our tests. Still the 1.5V AA IKEA Alkalisk alkaline batteries do manage to provide a very good price/performance ratio for everyday use without having some more specific requirements.

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

– 2127 mAh at 0.1A load
– 1845 mAh at 0.2A load
– 974 mAh at 0.5A load
– 310 mAh at 1.0A load

– 2.618 Wh at 0.1A load
– 2.230 Wh at 0.2A load
– 1.108 Wh at 0.5A load
– 0.344 Wh at 1.0A load
