Battery accident!!
I bought a battery last summer, Group 27 deep cycle. I just found out that it tipped over and spilled the electrolyte. Most of the acid is gone. I have no idea of the state of the left over acid, e...

Plates exposed to air sulphate within minutes. It may be possible to add electrolyte (enough to cover the plates) and then follow this procedure:
"It may be possible to salvage a battery with hardened sulfate. The battery should be charged from an outside source at 2.6 to 2.7 - volts per cell and a low current rate (approximately 5 Amps for small batteries and 10-Amps for larger ones) until the specific gravity of the electrolyte starts to rise. (This indicates that the sulfate is breaking down.) Be careful not to let the internal temperature of the battery rise above 125° F. If it does, turn the charger off and let the battery cool. Then, continue charging until each cell in the battery is brought up to full charge (nominal 1.265 specific gravity or higher).This time needed to complete this recharge depends on how long the battery has been discharged and how hard the sulfate has become."
If that doesn't work then you might do a last ditch attempt using epsom salts.
No matter what you do, the battery may exhibit lowered over all capacity.
