Mix 2/3 cup MgSO4 (drug store Epsom salt) with 1 Quart distilled water.
Heat over medium heat in a sauce pan until water reaches 150F while stirring to dissolve the MgSO4 (Epsom salt).
Disconnect and remove battery from car.
Use a siphon to remove some of the battery acid unless the levels are low enough to accommodate 1/2 quart of liquid.
Note: Always wear protective gloves, glasses, and chemical apron. Never under any circumstances should you let the acid from inside the battery touch any part of your body. It will eat through skin and clothing as it is H2SO4 (sulfuric acid).
Add an equal amount of the MgSO4/H2O solution into each reservoir of the battery until you have used up about 1/2 quart of the warm liquid.
Reinstall battery into car and try to start it.
If it won't start, try jumping it or charging it with a battery charger, but this is not likely needed as all you are doing is removing the sulfate coating on the metal plates in the battery's cell.
This method doesn't always work but if it does, it will not work more than 3-5 times so protect the charge on your battery and never let it go dead.

I just tried this method on my car 1 hour ago and it worked like a charm!

Good Luck!
