UPS systems also contain large banks of both DC electrolytic and AC polymeric film capacitors that degrade with time. The function of capacitors within the UPS is to filter out electrical fluctuations and provide clean power to the equipment being protected called “Supply Voltage Filtering” They are not static electrical components that operate in a circuit. Their design life is a mathematical function of manufacturers’ rated voltage, the voltage actually applied, the current running through them, ambient temperature, and thermal resistance. For all practical purposes, estimating service life would be based on manufacturers’ rated voltage combined with the device’s operating temperature.
Commonly at 7 year's service life span capacitor expires.
