The 1.2V AA 2700 mAh GP NiMH batteries are the largest capacity NiMHs offered by the company and we are expecting to see good results from them. With GP’s batteries we’ve seen quite interesting results in our tests, some models are a bit disappointing, others are surprisingly good, but since we’ve seen varying results with the highest capacity NiMH batteries from different brands we are hoping that GP did not make any compromise with their top model at least.

Starting the test of the 1.2V AA 2700 mAh GP NiMH batteries as we normally do with a low constant current discharge rate of 0.2A and the result was 2664 mAh as capacity which is great result for a battery rated at 2700 mAh (typical capacity), we can say that it is perfect. Furthermore increasing the constant current discharge rate at up to 2.0A the batteries continue to perform great offering great useable capacity levels. We can say for sure that the 1.2V AA 2700 mAh GP NiMH Rechargeable batteries are really good choice and are true to their ratings, unlike the not so well performing 2500 mAh model that we’ve tested some time ago that got us a bit disappointed.

The performance of the 1.2V AA 2700 mAh GP NiMH Batteries in our tests:

– 2664 mAh at 0.2A load
– 2527 mAh at 0.5A load
– 2404 mAh at 1.0A load
– 2223 mAh at 2.0A load

– 3.329 Wh at 0.2A load
– 3.082 Wh at 0.5A load
– 2.801 Wh at 1.0A load
– 2.436 Wh at 2.0A load

1.5V AAA GP Ultra Alkaline Battery Tests

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

1-5v-aaa-gp-super-alkaline-battery

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…


1-5v-aaa-gp-super-alkaline-battery-capacity

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
