Low Energy Density: Compared to other forms of energy storage like batteries, capacitors store less energy per unit of volume or mass, making them less suitable for long-duration energy storage. High Self-Discharge: Capacitors tend to lose their stored energy relatively quickly when not in use, known as self-discharge.
