Capacitor Deep Dive: Circuit Protection, Filtering, Storage
When you remove the battery from the capacitor each plate will still carry the charge from before, waiting to be discharged and returned to a more stable equilibrium state. If you shorted the two leads together the capacitor would act the same way as it did when it charged but in reverse, quickly returning to a steady state and slowing as fewer

Replacing a Motorcycle Battery with a Capacitor...
It''s not worth the bother. A capacitor costs more for a given capacity, and will occupy more volume. It might even be heavier. The only sensible use of a capacitor for starting that I''ve seen is a hybrid lead-acid with a capacitor. The battery charges the capacitor, which provides a large but brief surge current to start the engine.
