Here's another study for you, which shows a decrease in capacitance and increase in ESR (equivalent series resistance) of electrolytics operated in a DC-DC converter circuit at room temperature over extended periods of time. This shows that capacitors degrade even when used within their rated limits. https://www.researchgate.net/publication/228874152_Experimental_Studies_of_Ageing_in_Electrolytic_Capacitors https://www.researchgate.net/publication/228874152_Experimen...
