Electrolyte - The medium which provides the ion transport mechanism between the positive and negative electrodes of a cell.
UPS (parallel without redundancy) - A UPS made up of several (n) parallel-connected UPS units with equal output ratings (P) and each equipped with its battery, for large loads. The total output is equal to the number of units multiplied by their individual output (n x P). In this configuration, no UPS unit is redundant.
Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
Reversal - The changing of the normal polarity of a battery due to overdischarge.
Working Voltage - The typical voltage or range of voltage of a battery during discharge (also called operating voltage or running voltage).
High Voltage Spike - Rapid voltage peak up to 6000 volts with a duration of 100mS to 1/2 cycle.
Wall-less Design - A battery design where the structural support for the cells is formed by an open plastic framework.
