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
