I put 3 Tablespoons Magnesium Sulfate(epsom salt) into 1/2 cup Distilled Water and divide it into the 6 battery cells.

Start with 200 ca and 12.20 volts
1 day later 250 ca and 12.25 volts
1.5 weeks later 450 ca and 12.40 volts

I tested it a month and a half later and it was stable at 450 ca and 12.40 volts.

UPDATE 6-17-14
I just tested the battery almost 4 years later and it is still in great condition. It has went through 4 winters since the addition of Epsom salt and I haven’t had any issues with it. It cranked the vehicle effortlessly all winter. Source
