That makes no sense.. the circuit may draw 10mA, in which case a battery
with a capacity of 10mAh (at 10mA) will power it for an hour. A battery
with double the capacity will power it for twice as long.

If there was a timer in there, or some other kind of pathological case,
well, you'd say the circuit has a "requirement" of 10mAh.

When capacity > requirement you have a good situation, when capacity
< requirement you have an unsatisfactory situation (PIC quits too soon,
divorce, whatever).
