Self-Discharge - The loss of useful capacity of a battery on storage due to internal chemical action (local action).
IEC (International Electrotechnical Commission) - Advisory organization that draws up international standards in the electrotechnical field.
Safety installation - Installation supplying electrical equipment which may have a direct effect on the safety of users and must therefore remain energized even in the event of a mains failure. In general, characteristics concerning the power supply and conditions for transfer to the safety source for such electrical equipment are covered by applicable regulations.
Distortion (individual) - Ratio between the rms value of an nth order harmonic and the rms value of the fundamental.
Closed-Circuit Voltage (CCV) - The potential or voltage of a battery when it is discharging or charging.
Short-Circuit Current (SCC) - The initial value of the current obtained from a battery in a circuit of negligible resistance.
End Voltage (also see Cutoff Voltage) - The prescribed voltage at which the discharge (or charge, if end-of-charge voltage) of a battery may be considered complete.
