Recommended Maximum Allowable Impurities in Water for Battery Use
Impurity Parts Per Million Eects of Impurity
Color Clear and “White” -
Suspended Matter Trace -
Total Solids 100.00 -
Organic and Volatile Matter 50.0 Corrosion of positive plate
Ammonia 8.0 Slight self-discharge of both plates
Antimony 5.0 Self-discharge by local action, reduces life, lower on-charge voltage
Arsenic 0.5 Self-discharge, can form poisonous gas at negative
Calcium 40.0 Increase of positive shedding
Chloride 5.0 Loss of capacity in both plates, greater loss in positive
Copper 5.0 Increased self-discharge, lower on-charge voltage
Iron 3.0 Increased self-discharge at both plates, lower on-charge voltage
Magnesium 40.0 Reduced life
Nickel None Allowed Intense lowering of on-charge voltage
Nitrates 10.0 Increased sulfation at negative
Nitrites 5.0 Corrosion at both plates, loss of capacity, reduced life
Platinum None Allowed Violent self-discharge, lower on-charge voltage
Selenium 2.0 Positive shedding
Zinc 4.0 Slight self-discharge at negative
3.3 Cleaning
Observe the battery for cleanliness at regular intervals and keep terminals and connectors free of
corrosion. Terminal corrosion may adversely aect the performance of the battery, and it could present a
safety hazard.
î Check that all vent caps are secured properly on the battery.
î Clean the top of the battery, terminals and connections with a cloth or brush and a solution of
baking soda and water (1 cup of baking soda to 1 gallon of water).
Do not allow cleaning solution to get inside the battery.
