Maxell makes two kinds of Alkaline batteries and since we’ve tested both the standard 1.5V AA Alkaline as well as the Super Alkaline version of these batteries we’ve decided to make a direct comparison between them in order to see what is the difference. These two types of Alkaline batteries are performing very well and are providing a capacity that is a bit below the one provided by the Duracell Copper Top batteries that we are using as a reference for the standard Alkaline batteries and the Super Alkaline batteries are a bit better than the Duracells.

You can see that at low current drain the difference is about 6% at 0.1A constant current load in favor of the Super Alkaline version, at 0.2A their advantage is about 8%, at 0.5A we are back at about 6% and at 1A it is the highest at about 17%. So the Maxell Super Alkaline batteries are offering slightly better capacity than the standard Alkaline batteries that the company makes and while the difference at lower constant current loads is below 10%, at 1A load the Super Alkaline batteries manage to perform much better.

Maxell – Alkaline – Super Alkaline
0.1A load – 2237 mAh – 2377 mAh
0.2A load – 1807 mAh – 1959 mAh
0.5A load – 1010 mAh – 1070 mAh
1.0A load –   483 mAh –   566 mAh

In the end it is probably up to the price difference between the two types of batteries that can help you decide which one to buy, the standard Alkaline batteries are a bit cheaper than the Super Alkaline version from Maxell as to be expected. And while in general the Maxell Super Alkaline batteries are providing a bit more capacity at all load levels they are doing their best at the 1A constant current load test, meaning that they are definitely the better choice for applications with higher power requirements, though for others with lower power requirements you might still be Ok with the standard Alkaline batteries from Maxell.

The 1.5V AA Maxell Super Alkaline batteries are the higher-end Alkaline batteries that Maxell makes, the lower-end are labeled as just Alkaline batteries and we’ve already tested them, so our expectations from the Super Alkaline are to perform a bit better. The 1.5V AA Maxell Super Alkaline batteries we used for testing were with an expiration date of 01-2018, so they are supposedly offering quite a long shelf life. Maxell recommends the use of their Super Alkaline batteries for devices including portable radios, flashlights, radio control vehicles, MP3 players and portable GPS systems. And now let us see how good they will perform in our tests…

We have started the test of the 1.5V AA Maxell Super Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 2377 mAh as capacity and that is indeed a very good result. Increasing the constant current load to the higher values we use for testing the batteries continued to show very good performance and even in high loads they’ve managed to offer good performance. Since we’ve taken the standard 1.5V AA Duracell Copper Top batteries as a reference for well performing Alkaline batteries we can say that these Maxell Super Alkaline batteries do manage to outperform them in all four of the test loads we are using by a bit and that is definitely a good sign for Maxell.

The performance of the 1.5V AA Maxell Super Alkaline Batteries in our tests:

– 2377 mAh at 0.1A load
– 1959 mAh at 0.2A load
– 1070 mAh at 0.5A load
– 566 mAh at 1.0A load

– 2.978 Wh at 0.1A load
– 2.400 Wh at 0.2A load
– 1.263 Wh at 0.5A load
– 0.631 Wh at 1.0A load

The 1.5V AA Maxell Alkaline batteries are the mid-range Alkaline batteries from Maxell, they also have a Super Alkaline series that is supposed to offer a bit more capacity than this standard Alkaline models and we’ll test them s well to confirm. The 1.5V AA Maxell Alkaline batteries we got for testing here are with an expiration date of 01-2018, so they are offering quite a long shelf life, but let us see what they will offer in terms of capacity and how good they will perform compared to other Alkaline batteries we’ve tested so far…


1-5v-aa-maxell-alkaline-battery-capacity

Beginning our test of the 1.5V AA Maxell Alkaline batteries with a constant current discharge rate of 0.1A we’ve managed to get 2237 mAh capacity and that is a very good result though not the highest we’ve got from Alkaline batteries we’ve tested already. Increasing the constant current load further and these Alkaline batteries from Maxell still manage to perform quite well, so we can say that they are providing above the average capacity and this only rises our expectation from Maxell’s Super Alkaline batteries that are supposed to offer even better results.

The performance of the 1.5V AA Maxell Alkaline Batteries in our tests:

– 2237 mAh at 0.1A load
– 1807 mAh at 0.2A load
– 1010 mAh at 0.5A load
– 483 mAh at 1.0A load

– 2.775 Wh at 0.1A load
– 2.166 Wh at 0.2A load
– 1.164 Wh at 0.5A load
– 0.538 Wh at 1.0A load
