Save yourself some money with this old recipe.
Don't pay $14 for epsom salt and directions. All you need is 8 oz. of epsom salt and distilled water then follow these directions:
Tip the battery on its edge and allow approximately half the battery acid to run out of each cell and into a plastic container. Clean the battery with your paintbrush dipped in a baking soda solution. Rinse your battery with plain water, making certain none of the water gets into any of the cells.
Next, mix 8 ounces of Epsom salts into 2 quarts of warm distilled water. Stir thoroughly. Use a turkey baster to fill each battery cell with the Epsom salts solution until the cells are completely covered.
Last, charge the battery overnight. The Epsom salts should remove deposits on the battery plates which previously prevented the battery from taking a full charge. Check the battery in the morning. If the battery still won't take a full charge, it likely cannot be saved. If the battery has taken a charge, replace the cell caps and use your cart normally. Put a trickle charger on the batteries every night to keep the batteries in peak condition.
