Check Electrolyte Levels
Interval Perform this procedure quarterly.
Guidelines Maintain the electrolyte level between the black high- and low-level
lines on the battery jar. Electrolyte level checking requirements depend
upon local conditions. Historical data on the Round Cell indicates that
water may need to be added only once every 10 years.
• Use only distilled water, deionized water, or other water approved for
storage battery use, to bring electrolyte up to the required level.
When the actual electrolyte temperature is below 50°F (10°C), do not
raise the electrolyte level appreciably above the minimum level. This
helps to prevent an overflow on charge.
• Acid or electrolyte should not be added to any cell as a substitute for
adequate charging. Do not contaminate the electrolyte of Round
Cells by using the electrolyte from lead-calcium or lead-antimony
cells.
• Use the vent funnel on the cell to fill the cell to the proper level.
• Neutralize electrolyte with soda or lime before disposal to prevent
damage. Dispose of electrolyte according to local, state, and federal
regulations.
