Aging battery bank - What happens when sulfation doesn't kill a battery bank?

After enough plate material falls and fills the sump at the bottom the the battery, one cell will get shorted out from the debris. You might be able to shake, rinse and flush the debris out, but damage has been done, and material lost off the plates.

This is something I've often wondered about.... A sump must be deep enough to hold all that debris, but doesn't a deep sump become a place where concentrated sulfuric acid becomes sequestered? As normal stratification occurs, concentrated sulfuric acid will settle into the sump. The gassing that breaks up normal stratification only occurs above the sump.

I do not know the extent to which this process occurs, or just how deleterious this process is.
