Self-Discharge - The loss of useful capacity of a battery on storage due to internal chemical action (local action).
Constant Power Discharge - A battery discharge regime whereby the current during the discharge increases as the battery voltage decreases.
Desorption - The opposite of absorption, whereby the material retained by a medium or another material is released.
Distortion (total) - Ratio between the rms value of all harmonics of a non-sinusoidal alternating periodic value and that of the fundamental. This value may also be expressed as a function of the individual distortion of each harmonic Hn= Yn /Y1.
