Electrolytic capacitors typically don’t hold their charge as well as other types and will usually lose it in a matter of days to weeks, depending on the size. Ceramic capacitors tend to have a longer charge retention time, ranging from several months up to a year or more for larger capacitors.
Batteries typically have much larger capacities than capacitors, so they usually last for several hours or days depending on their type and usage pattern. On the other hand, due to their smaller capacity most electrolytic capacitors can only hold a charge for a few seconds or minutes before discharging.
Although larger capacitors are able to hold more charge for longer periods of time compared to smaller ones, their limit still exists. The maximum time that a capacitor can store a charge without losing any voltage depends on several factors such as temperature, humidity and frequency.
Ceramic capacitors tend to have a longer charge retention time, ranging from several months up to a year or more for larger capacitors. Film capacitors can also hold their charge for a long time, with some models able to retain their charge up to over several years.
The amount of time it takes for a capacitor to lose its charge depends on several factors, such as the type and size of the capacitor, the environment in which it’s stored, and the presence of any external circuits. Generally speaking, capacitors can hold their charge for anywhere between minutes up to years depending on the specific type.
Film capacitors can also hold their charge for a long time, with some models able to retain their charge up to over several years. It is also important to note that higher-value capacitors tend to have lower leakage rates and thus are better at retaining their charge than lower-value ones.
