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
