NOTE: The measured values for the specific gravity of the individual battery cells must not vary by more than 0.03 kg/cu.dm.
Examples of unacceptable variations in specific gravity:
Example 1:
The specific gravity in cell 4 is too low.
Example 2:
The specific gravity in cells 4 and 5 is too low (the difference in specific gravity the cells is greater than 0.03 kg/cu.dm).
-
If values are not met, replace battery.
-
If values are met, reinstall cell caps.
The original cell caps that came with the battery must be reinstalled to help prevent leakage.
If the cell caps are lost or damaged, use replacement cell caps of the same manufacture.
The cell caps must be equipped with an O-ring seal.
