Batteries aren''t really like capacitors at all aside from the fact that they can store energy. Capacitors are not used for energy storage they same way that batteries are (aside from super capacitors maybe), instead they can be thought of as buckets that can store small amounts (compared to a battery) of energy to supply extra current when switching on a chip occurs (i.e …
