A good example of a cycling application is one used for energy recovery, such as regenerative braking. Here the advantages of hundreds of thousands of cycles can be seen. Also, the very low equivalent series resistance (ESR) of a supercapacitor allows for very high round trip (charge & discharge cycle) efficiency, in the range of 97%+ values. Compared to the cycle life of batteries in the thousands, and round trip efficiency in the mid-80% range, this is a significant advantage. Some applications combine batteries and supercapacitors to take advantage of the strengths of both. In these cases, the supercapacitors are used for regeneration, where the higher efficiency and large number of cycles can be utilized, and the batteries for long term energy needs, where their higher energy density is an advantage.
