Lets get back on-topic and stay there guys. Thanks.To answer the OP, no, a cap should not discharge itself when there is no load on it. It should hold a charge for months, if not years, given no load to drain it. It may be that you have a bad cap (internal short), or that you are doing something wrong in your testing, its really hard to say for sure through a computer screen.Yes, caps are used all the time as an auxiliary power source for 'starting' an electric motor. Large electric motors such as those used on large air compressors have them, for example. Its a very common use for a capacitor. But if your cooling fan requires a cap to start properly, you have bigger issues, tbh.</blockquote>
