The 1.5V AAA GP Ultra Alkaline batteries are the mid-end Alkaline batteries from GP, even though the Ultra in the name may suggest they may be some high-end model. The Ultra Alkaline are intended for more power hungry devices, while the standard Super Alkaline batteries are for devices operating using lower power. As supposedly better Alkaline batteries GP also offer the Ultra Plus Alkaline series that we should be checking out in the near future. Anyway, the GP Ultra Alkaline batteries we tested here were with an expiration date set to 07-2019, meaning 6 years of shelf life. And now it is time to see what capacity they will be able to offer in our tests.

Beginning our test of the 1.5V AAA GP Ultra Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 877 mAh as capacity… a somewhat disappointing result, especially considering that the GP Super Alkaline batteries manage to get better result. The key here is that the 1.5V AAA GP Ultra Alkaline batteries are designed to handle better with devices requiring more power, so by increasing the load they start to show better results that the GP Super Alkaline batteries and going to loads of 0.3A and 0.5A they even manage to outperform by a bit the Duracell Alkaline batteries. So definitely a good choice for more power hungry devices and thus rising even higher our expectations for the GP Ultra Plus series that we still haven’t tested.

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

– 877 mAh at 0.1A load
– 728 mAh at 0.2A load
– 572 mAh at 0.3A load
– 355 mAh at 0.5A load

– 1.053 Wh at 0.1A load
– 0.839 Wh at 0.2A load
– 0.659 Wh at 0.3A load
– 0.401 Wh at 0.5A load

1.5V AAA GP Super Alkaline Battery Tests

The 1.5V AAA GP Super Alkaline batteries are the low-end Alkaline batteries from GP, then there is of course the Carbon Zinc as an even lower level, even though the Super in the name may suggest they may be some mid or even high-end solutions. As supposedly better Alkaline batteries GP also offer an Ultra Alkaline as well as Ultra Plus Alkaline series that we are also going to be checking out soon to see what kind of capacity they will be able to provide compared to the standard Super Alkaline. Anyway, the GP Super Alkaline batteries we tested here were with an expiration date set to 01-2019, meaning 6 years of shelf life and let us see what capacity you can expect to get from them as well…

Beginning our test of the 1.5V AAA GP Super Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 915 mAh as capacity, a result that is quite good for a “standard level” Alkaline batteries. Going to higher constant current discharge rates the batteries still do perform quite well, though at 0.5A load the result was a bit disappointing and thus hinting that these batteries are not designed for very high power applications. So in overall the capacity provided by the 1.5V AAA GP Super Alkaline batteries is very good.

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

– 915 mAh at 0.1A load
– 666 mAh at 0.2A load
– 487 mAh at 0.3A load
– 203 mAh at 0.5A load

– 1.097 Wh at 0.1A load
– 0.778 Wh at 0.2A load
– 0.550 Wh at 0.3A load
– 0.226 Wh at 0.5A load

1.5V AA GP Super Alkaline Battery Tests

The 1.5V AA GP Super Alkaline batteries are the mid-range model that offers high capacity for alkaline batteries from GP, so we were quite interested to see how these compare to other high-end alkaline batteries. These batteries are supposed to offer up to 7 years shelf life and the ones we’ve tested were marked for use up to 01-2019. GP offers also an Ultra lineup of Alkaline batteries that are supposed to offer even higher capacity than the Super lineup that we are testing here, so we should also check these models as well in the future. Bit for now let us see how the 1.5V AA GP Super Alkaline batteries can perform. GP’s website does not have a lot of useful information about the actual capacity that the Super Alkaline batteries should offer, so we are off to test to see what we can expect to get from them.


1.5v-aa-gp-super-alkaline-power-profile

Starting with the power profile test of the 1.5V AA GP Super Alkaline batteries we can see that they can handle pretty high loads before reaching the cutoff voltage of 1V that we are using for our tests. We’ve managed to reach up to 1.55A current draw before the batteries hit the cutoff voltage and values over 1 Amp are not that common to find with alkaline batteries, so these batteries from GP are handling pretty well actually up to this point. The open circuit voltage of the 1.5V AA GP Super Alkaline batteries we’ve tested with was 1.58V, though of course that value decreases when the battery is under load.

Moving on to the constant current draw tests we are performing and starting with a 0.1A load tests for the 1.5V AA GP Super Alkaline batteries we’ve managed to get 2231 mAh capacity which we consider to be quite good. Going for 0.2A constant current draw form the batteries the useful capacity you can expect is 1839 mAh and going even higher the useful capacity gets pretty much in half in our tests at 0.5A and 1.0A as compared to the previous rate. Nevertheless the 1.5V AA GP Super Alkaline batteries still manage to perform very well even under higher constant current draw rates, though as usual for such situations we would still recommend to go for rechargeable NiMH batteries instead as the better choice.

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

– 2231 mAh at 0.1A load
– 1839 mAh at 0.2A load
– 991 mAh at 0.5A load
– 458 mAh at 1.0A load

– 2.765 Wh at 0.1A load
– 2.197 Wh at 0.2A load
– 1.122 Wh at 0.5A load
– 0.504 Wh at 1.0A load
