1-5v-aa-varta-max-tech-alkaline-battery

The 1.5V AA Varta Max Tech Alkaline batteries are probably the highest-end Alkaline batteries that Varta makes, though that is not very clearly stated. The 1.5V AA Varta Max Tech batteries are labeled as +130% in digital cameras versus Varta Simply Alkaline we are expecting these to perform quite well in terms of the capacity they will provide in our tests. Varta positions these batteries for use in high-tech devices such as MP3 players, digital cameras, photo flashes etc. and the pack we picked-up for testing was with an expiration date of 06-2019 with the batteries supposed to have something like 7 years of shelf life. Anyway, lets us see how good with the Varta Max Tech batteries perform in our tests…


1-5v-aa-varta-max-tech-alkaline-battery-capacity

We have started the test of the 1.5V AA Varta Max Tech Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A and we’ve managed to get the surprisingly good result of 2748 mAh in terms of capacity – the highest for far we’ve got from an AA-size Alkaline battery! Going for a 0.2A constant current load these batteries still perform great and provide a lot of capacity and even further increasing the load they still manage to perform very well. So a great job from Varta with these batteries as they easily manage to beat the standard Duracell Copper Top Alkaline batteries in all of the load levels we test at, though at higher loads they may not be able to offer the maximum capacity among the models we’ve tested so far, they do it at the lowest level meaning that they are the best choice so far for application where the power requirements are low, even though they also perform great with applications requiring higher power and they are originally intended for such use.

The performance of the 1.5V AA Varta Max Tech Alkaline Batteries in our tests:

– 2748 mAh at 0.1A load
– 2114 mAh at 0.2A load
– 1078 mAh at 0.5A load
– 545 mAh at 1.0A load

– 3.390 Wh at 0.1A load
– 2.542 Wh at 0.2A load
– 1.216 Wh at 0.5A load
– 0.601 Wh at 1.0A load

1-5v-aa-toshiba-alkaline-batery

The 1.5V AA Toshiba Alkaline batteries are a standard Alkaline batteries with no fancy naming to tell you they are something special or different than normal primary batteries for single use. In fact these are the Standard Alkaline batteries from Toshiba, though they also have a lower-end Blue Line Alkaline batteries and higher-end named Alpha Power. The shelf life of the 1.5V AA Toshiba Standard Alkaline batteries is supposed to be 7 years and the expiration date of the ones we used for the tests here is 06-2019. According to Toshiba these batteries are ideal for portable radios, handheld computers, pagers, pocket electronic games etc. Surprising we even found something like a specs sheet for these batteries on Toshiba’s website, though it did not mention anything about expected capacity, you can find the link below.

We have started the test of the 1.5V AA Toshiba Alkaline batteries with a constant current discharge rate of 0.1A here we’ve managed to get 2467 mAh and that is nothing short of great performance at this level of constant current load. Furthermore going at 0.2A the batteries also performed superb, though at even higher constant current load levels their performance is a bit lower than the best performing models we’ve tested so far. So it seems that these Toshiba Standard Alkaline batteries are great for use in devices with lower power requirements, where they can provide the best performance they can. At lower constant current load these batteries were able to outperform the standard Duracell Copper Top Alkaline batteries, though at higher loads the Duracell performs slightly better.

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

– 2467 mAh at 0.1A load
– 1903 mAh at 0.2A load
– 1025 mAh at 0.5A load
– 324 mAh at 1.0A load

– 3.067 Wh at 0.1A load
– 2.286 Wh at 0.2A load
– 1.189 Wh at 0.5A load
– 0.352 Wh at 1.0A load

1-5v-aa-maxell-alkaline-battery

The 1.5V AA Maxell Alkaline batteries are the mid-range Alkaline batteries from Maxell, they also have a Super Alkaline series that is supposed to offer a bit more capacity than this standard Alkaline models and we’ll test them s well to confirm. The 1.5V AA Maxell Alkaline batteries we got for testing here are with an expiration date of 01-2018, so they are offering quite a long shelf life, but let us see what they will offer in terms of capacity and how good they will perform compared to other Alkaline batteries we’ve tested so far…


1-5v-aa-maxell-alkaline-battery-capacity

Beginning our test of the 1.5V AA Maxell Alkaline batteries with a constant current discharge rate of 0.1A we’ve managed to get 2237 mAh capacity and that is a very good result though not the highest we’ve got from Alkaline batteries we’ve tested already. Increasing the constant current load further and these Alkaline batteries from Maxell still manage to perform quite well, so we can say that they are providing above the average capacity and this only rises our expectation from Maxell’s Super Alkaline batteries that are supposed to offer even better results.

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

– 2237 mAh at 0.1A load
– 1807 mAh at 0.2A load
– 1010 mAh at 0.5A load
– 483 mAh at 1.0A load

– 2.775 Wh at 0.1A load
– 2.166 Wh at 0.2A load
– 1.164 Wh at 0.5A load
– 0.538 Wh at 1.0A load
