The 1.5V AA Xcell Alkaline batteries don’t seem as something special, but we’ve decided to give them a try and see how good will they be able to perform in our tests. The batteries we’ve used for testing were with an expiration date of just the year 2017, no specific month, so they should be with either 4 or 5 years of shelf life.

Starting our test of the 1.5V AA Xcell Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 2063 mAh as capacity. With that capacity they do not manage to get into our top 10 of best AA-size Alkaline batteries, though the level of capacity they offer is still more than decent if the price is right. Increasing the level of constant current load that we are testing with to 0.2A we still get a decent useable capacity, but past that the performance gets even worse, so better not use these batteries for higher power drain applications.

The performance of the 1.5V AA Xcell Alkaline batteries in our tests:

– 2063 mAh at 0.1A load
– 1586 mAh at 0.2A load
– 761 mAh at 0.5A load
– 267 mAh at 1.0A load

– 2.521 Wh at 0.1A load
– 1.858 Wh at 0.2A load
– 0.859 Wh at 0.5A load
– 0.293 Wh at 1.0A load

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
