The life of supercapacitors will double for every 10°C decrease in temperature or voltage by 0.1V. Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature. L1= Load life rating of the super capacitor (typically 1000 hours at rated temperature).
In theory, this table represents the lifetime of the supercapacitor, ranging from a little over one month of life to over 165 years! More realistic applications running the supercapacitor at full 6.0V and room temperature would achieve over 2.5 years of operation. Derating the voltage by only 0.2V will double that lifetime to over 5 years.
In other words, any voltage above the rated voltage for the capacitor will shorten its lifetime. In fact, it is better design practice to back of the system voltage, feeding the supercapacitor to a slightly lower value. Temperature is another variable that can be detrimental to energy storage components.
Fig. 1 Example of Derating Temperature and Voltage to Extend Lifetime. Abracon does not recommend operating supercapacitors out of their specified ranges. For example, designing a 0-700C supercapacitor into a system that will experience 850C ambient temperature is not recommended, regardless of whether the temperature increase is temporary.
Do capacitors last longer than batteries? Supercapacitors not only charge faster than batteries, they last longer because they don''t suffer the physical toll in charging and discharging that
However, by carefully managing voltage, temperature, and other stress factors, you can make supercapacitors last for decades or millions of lifecycles while delivering reliable power on
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.

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.
Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature.

But how long can they store energy effectively? This article breaks down the factors affecting their storage duration, real-world applications, and data-backed insights to help industries optimize their use.
Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature.
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
In theory, this table represents the lifetime of the supercapacitor, ranging from a little over one month of life to over 165 years!
Supercapacitor lifetime stems from chemical reactions in the capacitor causing the capacitance to decrease. These reactions happen more often when it is hotter and thus lifetime can vary
