Electrolyte - The medium which provides the ion transport mechanism between the positive and negative electrodes of a cell.
Charge Control - Technique for effectively terminating the charging of a rechargeable battery.
Polarization - The lowering of the potential of a cell or electrode from its equilibrium value caused by the passage of an electric current.
High Voltage Spike - Rapid voltage peak up to 6000 volts with a duration of 100mS to 1/2 cycle.
Duty Cycle - The operating regime of a battery including factors such as charge and discharge rates, depth of discharge, cycle duration, and length of time in the standby mode.
Reliability - Probability that a device will accomplish a required function under given conditions over a given period of time. Rms value of AC current with harmonics The rms value Yrms of a non-sinusoidal alternating current may be determined on the basis of the individual harmonic currents - where Y is the rms value of the fundamental.
Inverter - UPS subassembly that recomposes a sine-wave output (regulated and without breaks) using the DC current supplied by the rectifier-charger or the battery. The primary elements of the inverter are the DC/AC converter, a regulation system and an output filter.
