Impurity Parts Per Million Eects of Impurity
Color Clear and “White” -
Suspended Matter Trace -
Total Solids 100 -
Organic and Volatile Matter 50 Corrosion of positive plate
Ammonia 8.0 Slight self-discharge of both plates
Antimony 5.0 Increased self-discharge, reduces life, lower on-charge voltage
Arsenic 0.5 Self-discharge, can form poisonous gas at negative plate
Calcium 40 Increase of positive plate shedding
Chloride 5.0 Loss of capacity in both plates, greater loss on the positive plate
Copper 5.0 Increased self-discharge, lower on-charge voltage
Iron 3.0 Increased self-discharge at both plates, lower on-charge voltage
Magnesium 40 Reduced life
Nickel None Allowed Intense lowering of on-charge voltage
Nitrates 10 Increased sulfation on the negative plate
Nitrites 5.0 Corrosion of both plates, loss of capacity, reduced life
Platinum None Allowed Increased self-discharge, lower on-charge voltage
Selenium 2.0 Positive plate shedding
Zinc 4.0 Slight self-discharge of negative plate
