If the battery is dead because of shorting across the plates due to gunk build up at the bottom, there is sometimes a slight chance you may dump out the solution and install new acid, but 99 times out of a hundred, you have wasted your time.
Usually after a few years of use, the plates are shot.
You can buy rebuilt batteries, but they are never as good or powerful as new ones.
