Inverter (on-line) - UPS configuration in which the inverter is in series mounted between the mains and the load. All power drawn by the load passes via the inverter. This is the only configuration used for high outputs.
Forced Discharge - Discharging a cell in a battery, by the other cells or an external power source, below zero volts into voltage reversal.
Bobbin - A cylindrical cell design utilizing an internal cylindrical electrode, and an external electrode arranged as a sleeve inside the cell container.
Service Life - The period of useful life of a battery before a predetermined end-point voltage is reached.
Noise level - Acoustical decibel level of a source of noise, measured according to the applicable ISO standard.
Brownout - A steady state RMS voltage under nominal by relatively constant percentage.
Microsecond - 1,000,000th of a second (mS).
