Circuit breaker (battery) - DC circuit breaker that protects the battery of a UPS.(back)
MTBF (Mean Time Between Failures) - Mathematical calculation of the duration of normal operation of a repairable device between failures. The product, expressed in hours, is an indication on the reliability of the device.
Capacity Retention (or Charge Retention) - The fraction of the full capacity available from a battery under specified conditions of discharge after it has been stored for a period of time.
Electrode - The site, area or location at which electrochemical processes take place.
Battery or Pack - Two or more electrochemical cells electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current levels. Under common usage, the term "battery" is often also applied to a single cell.
Energy - The output capability of a cell or battery, usually expressed in watt-hours.
RMS Voltage - The range of usable voltage + or - 170 VAC.
