• EEVblog #774 – Low Battery Discharge Testing Part 1


    Dave shows how to do discharge testing on AAA and AA alkaline batteries, for the specific purpose of investigating how much energy is left under the industry standard 0.8V cutout voltage.
    This is an explanation of the test setup, verification, and a sample plot of some data before the long term testing.
    The setup consists of the BK Precision 8500 electronic load, the Keysight 34470A 7.5 digit meter, and the Rigol DP832 for testing.
