Load (non-linear) - Load (generally with a switched-mode power supply) generating major harmonic currents. Current wave form is different from voltage wave form. Ohm's law is not applicable. It can be used only with each harmonic.
Electrolyte - The medium which provides the ion transport mechanism between the positive and negative electrodes of a cell.
Constant Power Discharge - A battery discharge regime whereby the current during the discharge increases as the battery voltage decreases.
Polarization - The lowering of the potential of a cell or electrode from its equilibrium value caused by the passage of an electric current.
Rechargeable (or "Secondary") Battery - A galvanic battery which, after discharge, may be restored to the fully charged state by the passage of an electrical current through the cell in the opposite direction to that of discharge.
Energy Density - The ratio of the energy available from a battery to its volume (Wh/L) or weight (Wh/kg).
C-Rate (also see Hourly Rate) - Discharge or charge current, in amperes, expressed in multiples of the rated capacity. For example, C/10 discharge current for a battery rated at 1.5 Ah is:
