Eaton Supercapacitors :
Have Symmetrical electrodes, meaning they are similar in composition
When a Supercapacitor is first assembled, either electrode can be designated positive or negative.
Once the Supercapacitor is charged for the first time, the electrodes
Although Supercapacitor can be shorted to Zero volt – electrodes maintain a very small amount of charge.
The longer they are held charged in one direction, the more polarized
If reversed charged after prolonged charging in one direction, will reduce Supercapacitor life
