BATTERIES
Interpreting the Results of the Hydrometer Test
The approximate state of charge can be determined from the following table:
SPECIFIC GRAVITY (TEMPERATURE CORRECTED)
If the difference between the cells is 0.020 or more, the low cell should be suspected. It may require a catch-up
charge or it may be a weak cell. When the variations between cells reach 0.050 or more, the battery with the low
cell should be replaced.
