The 9V Sony Ultra Super Carbon Zinc batteries we test here are rated with up to 3 years shelf life and are marked for use up to 11-2015. The Sony website does not have detailed specifications about these batteries, so we have to check them out by testing the actual capacity we can get out of these. Considering the fact that we are talking about a Carbon Zinc battery we don’t have very high expectations, even though Sony labels these batteries as Ultra Super.

To test the capacity that 9V Carbon Zinc batteries can provide we are using a constant current discharge test with 0.05A load (50 miliampers) due to the fact that the total capacity of these batteries is not that high and they are not intended for use in situations where high current loads can be expected. The 9V Sony Ultra Super Carbon Zinc battery we have tested here managed to provide 151 mAh capacity before hitting the 5.4V cutoff voltage and that is actually quite normal performance for a 9V Carbon Zinc battery as these usually provide less capacity than Alkaline batteries and are a bit cheaper compared to Alkaline.

The performance of the 9V Sony Ultra Super Carbon Zinc Batteries in our tests:

– 151 mAh at 0.05A load

– 0.998 Wh at 0.05A load
