1.5V AAA Xcell Alkaline Battery Tests

The 1.5V AAA Xcell Alkaline batteries are nothing special at first look and are not a popular or well known brand, so we took them for a spin to see how good they will perform in our tests, The particular batteries we are testing here were all marked with an expiration of 2017, no particular month mentioned so we can assume they have a shelf life of 4 years.

Starting our test of the 1.5V AAA Xcell Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 893 mAh as capacity – a decent achievement, though a bit far from the highest result we’ve seen. Increasing the load to 0.2A, 0.3A and even at 0.5A the useable capacity we’ve got was still very decent. The interesting thing here is that the difference between the shown useable capacity at the higher test loads was with smaller gaps, indicating that these batteries are designed to handle well higher current loads. The Xcell Alkaline batteries seem to perform well, but are nothing special in terms of performance…

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

– 893 mAh at 0.1A load
– 532 mAh at 0.2A load
– 400 mAh at 0.3A load
– 314 mAh at 0.5A load

– 1.072 Wh at 0.1A load
– 0.600 Wh at 0.2A load
– 0.450 Wh at 0.3A load
– 0.351 Wh at 0.5A load

1.5V AAA Maxell Super Alkaline Battery Tests

The 1.5V AAA Maxell Super Alkaline batteries are supposedly better than standard Alkaline batteries that Maxell makes and are intended for high-drain devices according to the company. The batteries we’ve had for testing were with an expiration date of 01-2017 meaning that the shelf life is at least 4 years, though we are not exactly sure when these batteries were produced so it might also be 5 years. Anyway, let us see how good these 1.5V AAA size Alkaline batteries from Maxell perform in terms of useable capacity in our tests…

Starting our test of the 1.5V AAA Maxell Super Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 948 mAh as capacity and that is actually a very good result. Increasing the load to 0.2A and 0.3A the Maxell batteries do manage well, and even at 0.5A the useable capacity was still quite decent. In overall these Alkaline batteries seem to be doing quite well, but do not provide as much capacity as an Alkaline Duracell battery of the same type for example does (we use Duracell as a reference), so there is more to be desired.

The performance of the 1.5V AAA Maxell Super Alkaline batteries in our tests:

– 948 mAh at 0.1A load
– 572 mAh at 0.2A load
– 474 mAh at 0.3A load
– 253 mAh at 0.5A load

– 1.135 Wh at 0.1A load
– 0.675 Wh at 0.2A load
– 0.552 Wh at 0.3A load
– 0.282 Wh at 0.5A load

1.5V AAA Duracel Copper Top vs Duracell Procell Alkaline Batteries

We have already tested both the 1.5V AAA Duracell Alkaline batteries and the 1.5V AAA Duracell Procell Alkaline batteries and they both did perform really well by providing very high capacities for AAA-sized Alkaline batteries. Since there is a common belief that the Duracell Copper Top Alkaline batteries are actually the same as the Duracell Procell Alkaline we are going to compare both types and see if they are indeed the same batteries with different labels or there is an actual difference as Duracell claims in favor of the Procell batteries.

You can see that at low current drain the difference is about 7% at 0.1A in favor of the Procell, however as the current draw increases to 0.2A the gap decreases a bit to just about 2.5%. Though at the at 0.3A load the Procell batteries take significant lead with close to 14% and by and going to 0.5A the difference in useable capacity you get gets even higher with about 35% in favor of the Procell batteries. So the 1.5V AAA Duracell Procell Alkaline batteries are actually better than the 1.5V AAA Duracell Copper Top Alkaline batteries especially when the load on the batteries gets higher, meaning that we are talking about different batteries indeed.

Duracell – Copper Top – Procell
0.1A load – 970 mAh – 1038 mAh
0.2A load – 777 mAh – 797 mAh
0.3A load – 553 mAh – 627 mAh
0.5A load – 336 mAh – 455 mAh

So in the end if you are going to be using AAA batteries in a low load applications such as a remote control for a TV for example, then you might just go with the standard Duracell Alkaline batteries as the difference in capacity in such situations is probably something that you will not notice at all… unless you manage to find Procells at a better price than the standard Duracell Copper Tops. For applications that require more power however such as remote controlled toys for example you should consider choosing the Procells as they will definitely be able to offer you significantly more.
