Blackout - A zero voltage condition lasting for more than two cycles. Same as a power failure
Intermittent Test - A test during which a battery is subjected to alternate periods of discharge and rest according to a specified discharge regime.
Positive Temperature Coefficient (PTC) - A thermally reactive device which becomes highly resistive at a specific temperature or current.
Current (float) - DC current that maintains the battery at nominal charge, corresponding the float voltage. This current compensates open circuit losses.
Pulse Current - A periodic current drain of higher than normal drain rates.
Distortion (individual) - Ratio between the rms value of an nth order harmonic and the rms value of the fundamental.
Current loop (20 mA) - Transmission system used on certain devices and offering better performance than the RS232C. It provides a high degree of immunity to interference and is easy to implement, but has not been standardized.
