*NONE* of the _charge_ is written off. It is energy that is lost and
in your example, most of it _is_ lost through friction and heating
the water. To whit: moving charge constitutes kinetic energy, static
charge constitutes potential energy. As Ed Phillips says, integrating
the loss over time shows the rate of loss mkes no difference to the
final total loss.
