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.
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
1.5 Ah/10 = 150 mA (A cell's capacity is not the same at all discharge rates and usually increases with decreasing rate.)
Polarization - The lowering of the potential of a cell or electrode from its equilibrium value caused by the passage of an electric current.
Blackout - A zero voltage condition lasting for more than two cycles. Same as a power failure
UPS (single) - A UPS made up of one single UPS unit (rectifier/charger, inverter and bypass) and a battery.
Thermistor - A temperature sensitive resistor, usually made from specially processed oxides.
