aa-battery-highlighted

We have already tested more than 10 various 1.5V AA-size primary batteries (single use non-rechargeable models) from various brands including some of the most popular such as Duracell, Energizer, Panasonic, Toshiba, Varta and others so we have decided to do a little ranking by listing the top performing models in our tests in the various load scenarios we are using for testing. As a reminder we are using constant current load tests with 0.1A, 0.2A, 0.5A and 1.0A for the 1.5V AA-size Alkaline batteries, so we are going to rate the best batteries in four different charts as we’ve seen that one battery that performs very well under low load may not be the best with higher load and vice versa…

We are going to be updating these charts as we test new batteries in order to get a clear view of the situation with battery capacity and what batteries will work best for your specific needs. Have in mind that it is not always up to the highest capacity and you should always take into consideration the price of the batteries as well. For example if the second battery in the chart offers just 1% less capacity, but you can buy it for 30% less then you might sacrifice the minimal gain in extra capacity because of the much better price, so do have that in mind as well.

1-2v-aa-2300-mah-maxell-rechargeable-nimh-battery

The 1.2V AA 2300 mAh Maxell Rechargeable NiMH batteries we got for testing here are rated as 2300 mAh minimum capacity and that is the number printed on their package and this kind of surprised us as usually NiMH battery manufacturers print with big numbers on the front the typical capacity and somewhere else with small letters the minimum capacity that their cells should provide. The 2300 NiMHs we’ve got for testing apparently are now being replaced with a newer model that offers 2500 mAh capacity, though as it was not yet available in the shop we got these from we got only the 2300 mAh version.


1-2v-aa-2300-mah-maxell-rechargeable-nimh-battery-capacity

We have started the test of the 1.2V AA 2300 mAh Maxell Rechargeable NiMH batteries with a low constant current discharge rate of 0.2A (the lowest load for AA NiMHs in our tests) and the result we got was 2328 mAh capacity. This value is well within the minimum capacity rating for the batteries, so we can say these Maxell NiMHs perform very well and furthermore increasing the load to 0.5A and 1.0A the batteries not only manage to still provide very good level of capacity, but the difference is actually quite small between the two and even at 2.0A load we still get good capacity. So the 1.2V AA 2300 mAh Maxell Rechargeable NiMH batteries do manage to perform very well not only in lower load applications, but in a very high ones as well by providing good capacity in various applications requiring more power.

The performance of the 1.2V AA 2300 mAh Maxell Rechargeable NiMH Batteries in our tests:

– 2328 mAh at 0.2A load
– 2182 mAh at 0.5A load
– 2156 mAh at 1.0A load
– 1547 mAh at 2.0A load

– 2.902 Wh at 0.2A load
– 2.640 Wh at 0.5A load
– 2.469 Wh at 1.0A load
– 1.598 Wh at 2.0A 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.


1-5v-aaa-duracel-copper-top-vs-duracell-procell-alkaline-batteries-capacity

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.
