The 9V Maxell Alkaline batteries we test here are rated with up to 5 years shelf life and are marked for use up to 01-2018. The Maxell 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.

To test the capacity that 9V alkaline 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. Nowadays the 9V batteries find their place in different battery operated measuring equipment with low power requirements such a multimeter for example. The 9V Maxell Alkaline battery we have tested here managed to provide 432 mAh capacity before hitting the 6.6V cutoff voltage and that is quite good performance for a 9V alkaline battery.

The performance of the 9V Maxell Alkaline Batteries in our tests:

– 432 mAh at 0.05A load

– 3.251 Wh at 0.05A load
