This is caused by a residual leakage current, which is made up of various mechanisms. Since temperature-dependent self-discharge effects can have a very large impact on the performance of

The real self-discharge time will vary greatly depending on just about everything. It will of course vary from cap to cap, but also by temperature, age, and lots of other things.

Leakage current is a charge maintaining current while the supercapacitor is on charge. In order to calculate required backup time over system operating temperature range, designers need to take a

Self-discharge is the rate of voltage decline when the capacitor is not connected to any circuit. The rate of self-discharge is dependent on the state of charge it was held out before being disconnected from
