Do capacitors automatically release their energy over time?

4. Capacitors will lose their charge over time, and especially aluminium electrolyts do have some leakage. Even a low-leakage type, like this one will lose 1V in just 20s (1000 μ μ F/25V). Nevertheless, YMMV, and you will see capacitors which can hold their charge for several months. It''s wise to discharge them.

Energy of a capacitor (video) | Khan Academy

Capacitors store energy as electrical potential. When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not necessarily the battery ...

Energy storage

A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. Capacitors are commonly used in electronic devices to maintain power supply while batteries change. (This prevents loss of information in volatile memory.)
