Tests and reviews of different batteries to help you find the Right One…
The 9V Varta High Energy Alkaline batteries we are testing here are what the manufacturer considers to be the most powerful of all of their Alkaline batteries series that were developed especially for power-hungry devices, e. g. toys, audio equipments, LED flashlights and computer devices. We’ve seen very good results from the AA and AAA size Varta alkaline batteries so we also have high expectations here as well. The expiration date of the tested battery here was 08-2018, so quite a lot of time left for use before expiring.
In order to test the capacity of the 9V Varta High Energy Alkaline batteries we are using a constant current discharge rate of 0.05A (50 miliampers) and we have managed to get just 258 mAh. With this result and Varta claiming that their High Energy Alkaline batteries are the best they offer we are quite disappointed, we expected to see more from these batteries in our tests, so while Varta’s AA and AAA size Alkaline batteries have shown great results in our tests their 9V Alkalines are apparently not that good.
The performance of the 9V Varta High Energy Alkaline batteries in our tests:
– 258 mAh at 0.05A load
– 1.895 Wh at 0.05A load
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…
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
The 1.5V AA Varta High Energy Alkaline batteries are a slightly improved version of the Varta Simply Alkaline batteries and according the the manufacturer these should be able to provide 23% more power than the normal Varta Alkaline batteries. The batteries we have tested here have an expiration date of 06-2016, so they should be with a 5 year shelf life as they appear to have been produced in 07-2011. Varta does not provide detailed specifications about these batteries, but the company recommend their use for power-hungry devices, e.g. computer devices, audio equipments, toys etc. So lets us see how good these batteries perform in our tests.
Starting the tests of the 1.5V AA Varta High Energy Alkaline batteries with a constant current discharge rate of 0.1A we were very pleasantly surprised by the result we got – 2700 mAh capacity or with other words one of the best performing 1.5V AA-size Alkaline batteries we’ve tested so far with low current constant load. Moving to higher constant current loads these Varta batteries still perform great outperforming for example the standard Duracell Copper Top batteries by a bit and these are not the “toughest” Alkaline batteries from Varta. Compared to the Duracell Procell batteries however the 1.5V AA Varta High Energy Alkaline batteries only manage to provide slightly more capacity at 0.1A constant current load, but at higher loads the Procell performs better. Anyway, we are seeing a really great performance from these Varta batteries.
The performance of the 1.5V AA Varta High Energy Alkaline Batteries in our tests:
– 2700 mAh at 0.1A load
– 1941 mAh at 0.2A load
– 1216 mAh at 0.5A load
– 537 mAh at 1.0A load
– 3.332 Wh at 0.1A load
– 2.327 Wh at 0.2A load
– 1.371 Wh at 0.5A load
– 0.589 Wh at 1.0A load
