When it comes to the longevity of battery storage systems, you can generally expect them to last between 10 and 12 years. That said, some premium models can keep going for up to 15 years or

A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit mass or energy per unit volume than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.

During the service life of a supercap, the capacitor loses capacitance (C) and the equivalent serial resistance (ESR) increases. The service life has reached its end when the capacitance has fallen to

The life expectancy of supercapacitors is similar to aluminum electrolytic capacitors. The life of supercapacitors will double for every 10°C decrease in temperature or voltage by 0.1V.

The short answer is no, but they can last an exceedingly long time. This idea of supercapacitors lasting forever comes from comparing them to batteries. Supercapacitors are based
