60f 2.7v ultra capacitor

This listing is for a 60 farad 2.7v super capacitor! Use them to replace batteries! They are capable of a very fast charge due to low internal resistance (ESR), and can be charged thousands and thousands of times! Environmentally safe! See below for some specifications! These work great with solar panels, and are easy to charge. Don't know anything about super capacitors?
