If the discharge circuit is not present/functional, it can be months[1], even if the capacitor was discharged at one point.

When working with high voltage/power equipment, its best practice to keep the capacitors shorted while you are working to keep dielectric absorption from “recharging” the capacitor to 1-15% of its rated voltage.

Wow, I was not aware. Nice tip. Does this also apply to TVs and computer monitors from the 1990s? Are they high enough voltage/power?
