You can do it, but I think Christ is probably right - the battery is toast. Giving it a drink probably won't do an awful lot.

By next fall, and the first cold morning, you'll definitely need a new one.
If you would have caught the battery a little sooner giving it a drink would definately help, if you can get cheap EDTA or build a desulphator, give it a drink and you can definately bring it back if the voltage stays at 12v or higher.

Every battery in my yellow electric car was dry, a little edta and lots of charge cycles later they are working 3 yrs later, albeit not as well.
