W.W. Donovan has a way to avoid (temporarily, at least) being inconvenienced by a dead battery cell. Mr. Donovan, a Floridian who resides in Titusville, says the following "fix" works about 90% of the time. Using a hydrometer, he first finds which cell is dead, and adds one teaspoon of Epsom salts to that "empty pocket". Next, W.W. tops off all the cells with water and places the battery on a charger. If no charge can be measured, he adds another teaspoon of Epsom salts. If after three such applications no charge is noticed, the battery falls in the 10% failure category. However, the Sunshine Stater says this cure should carry most batteries through a few more months (perhaps until you can afford to buy a new one).
