The 1.5V AAA Panasonic Pro Power Alkaline are supposed to offer premium energy for personal appliances and should be ideal for high and medium drain appliances according to Panasonic. They are almost the highest-end Alkaline batteries that the company offers, the only supposedly better option are the ones in the Evolta range. The Panasonic Pro Power Alkaline batteries we tested here were with an expiration date of 01-2018 meaning that they should be offering at least 5 years shelf life.

Starting our test as we usually do with a low constant current discharge rate of 0.1A we have managed to get 794 mAh as capacity from the 1.5V AAA Panasonic Pro Power Alkaline batteries, or a it disappointing result placing them more in the mid-range among the AAA size Alkaline batteries we have tested so far. At 0.2A and 0.3A constant current discharge rates the batteries still perform quite well, though at a level of 0.5A there is a more significant drop in the usable capacity you can get, meaning that these batteries are not going to be handling well in devices that have quite high power requirements and are using AAA-size batteries.

The performance of the 1.5V AAA Panasonic Pro Power Alkaline batteries in our tests:

– 794 mAh at 0.1A load
– 593 mAh at 0.2A load
– 492 mAh at 0.3A load
– 159 mAh at 0.5A load

– 0.964 Wh at 0.1A load
– 0.707 Wh at 0.2A load
– 0.568 Wh at 0.3A load
– 0.173 Wh at 0.5A load

The 1.5V AAA Varta Max Tech Alkaline batteries are the higher-end version of Alkaline batteries that the company has and are intended for use with high-tech devices, e.g. mMP3 players, digital cameras, photoflash etc. according to Varta. Varta also has a High Energy series that is intended for use with more power hungry devices and is regarded as the most powerful of all Varta Alkaline batteries. The Max Tech batteries we’ve had for testing here were with an expiration date of 06-2017.

Beginning our test of the 1.5V AAA Varta Max Tech Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get just 787 mAh as capacity, so we were a bit disappointed as with the AA size batteries of the same type we’ve got the highest capacity among all models we’ve tested and we expected to see similar excellent results here as well. Going for higher constant current discharge rate the batteries still did not perform as good as we’ve expected them, so they were not like a high-end model, but the performance was more like a mid-end ones. And while the results we’ve got were still very decent, we are a bit disappointed as we expected more, and we should of course also test the High Energy models to see how well will they perform as well.

The performance of the 1.5V AAA Varta Max Tech Alkaline batteries in our tests:

– 787 mAh at 0.1A load
– 597 mAh at 0.2A load
– 453 mAh at 0.3A load
– 202 mAh at 0.5A load

– 0.942 Wh at 0.1A load
– 0.693 Wh at 0.2A load
– 0.510 Wh at 0.3A load
– 0.222 Wh at 0.5A load

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

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.


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

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
