We have picked up a 8.4V Duracell Recharge Ultra NiMH battery rated at 170 mAh capacity to test out and compare with other batteries of this type we have already tested. The 8.4V NiMH category is still not well represented in our tests, so we are trying to fix that by adding more batteries to test, but it will take some more time. The 170 mAh capacity is lower than anything we have tested so far, there are alternatives available with higher capacity available on the market than what Duracell is offering with this product.
We are doing our regular 0.05A constant current discharge test for this type of batteries with a cut-off voltage set a 7V to check the usable capacity in mAh and Wh that the 8.4V 170 mAh Duracell Recharge Ultra NiMH battery can actually deliver. We got 158 mAh as usable capacity in our tests and while it is a bit short of the rated capacity it is not that bad, the result however shows that this particular battery might not do that well when used in more power demanding applications.
The performance of the 8.4V 170 mAh Duracell Recharge Ultra NiMH Batteries in our tests:
– 158 mAh at 0.05A load
– 1.384 Wh at 0.05A load

We have recently tested 9V Duracell Industrial Alkaline Battery and surprisingly managed to find another one that is at the end of it’s shelf life this month. That was a good opportunity to compare a fresher 9V Duracell Industrial battery with one that is and the end of its expiration date and see what is the change in capacity you can expect to get with the 9V Duracell Industrial batteries compared to a battery that is at around half of its shelf life.
We were quite pleasantly surprised by the result we got, at a little over 300 mAh for a battery that should be considered expired in a couple of days and would normally be discarded and thrown away. This is just less than 15% lower capacity than that of a 3 years fresher 9V Duracell Industrial alkaline battery, so do not be in a hurry to throw away alkaline batteries that are near their end of life if you still have not used them as they may actually have more to offer than what you expect. Of course it is also very important under what conditions they were stored, because if not properly stored they could actually end up completely discharged even before the end of their expiration date!
Duracell – Fresher Industrial – Expiring Industrial
0.05A load – 347 mAh – 303 mAh
0.05A load – 2.562 Wh – 2.191 mAh
9V Duracell Industrial Alkaline Battery Test
21, Mar 2019
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
