Airplane Batteries

Nope, the acid in the electrolyte has to be replaced if you
drain. The water is what breaks down during the
charge/discharge cycle, so you only add water to a working
battery.

The act of draining the sludge would move the sludge into
the spaces between the plates, destroying the battery. Just
buy a new one and re-cycle the old one, they will melt it
down and make bullets, wheel weights and more batteries.
