I think the plates inside them corrode.
But hey, it's worth a shot for a free battery huh?

The material that is left in the battery (besides the obvious plates) are the solids that remained after evaporation. By adding just water, you recreate an acid as these solids go back into solution. Which is why, when batteries are low, we add water to them, not more acid. However, the shelf life of dried batteries is problematical.
hmm yes ill see if i can salvage them refilling with distilled water see if i get lucky thanx man on that explanation
i just thought a little new acid added to the water mix would help

This is why you don't add acid to an old batery that discharged and dried up...
a dry fresh battery from the sto' has one plate that's like a lead dioxide foam coating a lead screen.
When the battery discharges:
lead dioxide (positive plate) and lead (negative plate) react with sulfuric acid to create lead sulfate, water and energy.
The lead sulfate ends up on the negative plate
When you charge it:
lead sulfate and water are electro-chemically converted to lead, lead oxide and sulfuric acid by an external electrical charging source.
So if you have an old battery that's discharged and dried out, the lead oxide is gone. All you have is a bunch of lead sulfate on the negative plate. If you are real lucky and battery was good when it dried out and it has been handled like nitroglycerin so as not to shake the dried out lead sulphate off the negative plate, you might get it to recharge by filling with distilled water. Personally, I would add about 1 part fresh sufuric acid to about 9 parts water. This is because there is usually a little more lead dioxide than 'the perfect balance'. Let it sit a few hours, and then try to charge it.
If it's been dropped an inch or two, moved around in the back of a truck, or jostled pretty hard...chances are it needs to go to the recycler.
