Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.

Do electrolytic capacitors have a limited shelf life?

If the capacitors have been in hot, or very cold regions for extended time, then the electrolyte might leak out under pressure, or dry out with time. There are electronic devices that are decades old and still working just fine, capacitors and all. Sitting unused is essentially the same behavior as "shelf life."
