If the question is about an automotive battery, then:
Reserve capacity minutes (RCM), also referred to as reserve capacity (RC), is a battery's ability to sustain an electrical load; it is defined as the time (in minutes) that a lead-acid battery at 80 °F (27 °C) will continuously deliver 25 amps before its voltage drops below 10.5 volts.
reserve capacity  noun Automotive .the capacity of a battery, measured in minutes, to keep a vehicleoperating if the charging system fails.

Vital capacity is the amount of air you can breathe out after a maximum inhale. When it comes to determining vital capacity it’s basically calculated by the inspiratory reserve volume in addition to the expiratory reserve volume.
Cardiac reserve capacity refers to the ability of the heart to increase its output in response to increased demands or stress, such as during exercise or times of illness. It is the difference between a person's current cardiac output and the maximum cardiac output they are capable of achieving. Increased cardiac reserve is associated with better cardiovascular fitness and health.
inspiratory reserve volume= expiratory reserve volume + Tidal Volume - Vital capacity
It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume
Expiratory reserve volume, tidal volume, inspiratory reserve volume, you amateurs

Fuel capacity; Fuel Tank 4.17 US GAL Reserve capacity; 0.58 US GAL
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
