9V Q-Lite Alkaline Battery Tests

10 Aug


The 9V Q-Lite Alkaline batteries we test here are rated with up to 3 years shelf life and are marked for use up to 01-2015. The Q-Lite Industrial’s 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. What you should be well aware of is the fact that 9V batteries consist of multiple small 1.5V cells (six cells) with much lower capacity than a single AA size 1.5V battery for example can provide.


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 these batteries find their place in different battery operated measuring equipment with low power requirements such a multimeter for example. The 9V Q-Lite Alkaline battery we have tested here managed to provide 466 mAh capacity before hitting the 6.6V cutoff voltage and that is actually a very good performance for a 9V alkaline battery.

The performance of the 9V Q-Lite Alkaline Batteries in our tests:

– 466 mAh at 0.05A load

– 3.540 Wh at 0.05A load
