Is the button battery's internal resistance great?
If the short circuit is of course not only 0.2A, but this time the resulting polarization resistance will lead to increased power consumption in the battery.
If you want to increase the current can only reduce the load impedance, because the button battery voltage is certain, there is no other way.
Under normal circumstances, not large, very small, the small supply current is the internal material problem, only to this level.
