Polarity - In electricity, the condition of being positive or negative.
Electrolyte - The medium which provides the ion transport mechanism between the positive and negative electrodes of a cell.
Tolerance in % - Limit for allowable variations for a given quantity, expressed as a percent of the rated value.
Separator - An ionic permeable electronically nonconductive spacer or material which prevents electronic contact between electrodes of opposite polarity in the same cell.
ISO 9002 - Standard defining procedures and systems used to attain an internationally recognized level of production quality. ISO 9002 certification is proof that the quality system effectively complies with the standard. Certification is carried out by an official organization (AFAQ), unaffiliated with either clients or suppliers or the company itself, and is valid for a three-year period with yearly audits and checks.
Output (rated) - Apparent power Pn that the UPS can deliver under given load conditions (power factor = 0.8).
Forced Discharge - Discharging a cell in a battery, by the other cells or an external power source, below zero volts into voltage reversal.
