If the capacitor reads as having fewer than 10 volts, you don''t need to discharge it. If the capacitor reads anywhere between 10 and 99 volts, discharge it with a screwdriver. If the capacitor reads in the hundreds of volts, the safest way to discharge it is with a discharge tool, rather than a screwdriver.
In addition, the ESR change as the part changes varies widely between manufacturers. As noted above, ESR is largely affected by the interconnects. Thus, the device model and form factor have a large effect on ESR. So, coin cells are orders of magnitude higher than cylindrical cells which are orders of magnitude higher than large axial cells.

Another reason why super capacitors are so awesome! 3) If you are charging super capacitors, you will have to be careful. Not for your own safety, but rather the safety of your power supply. Super capacitors will take in as much current as humanly possible, and will look like a dead short on your power supply, which can cause fuses to blow.
