Hydrometer Calibration
Most hydrometers are calibrated to read correctly at 80°F. The readings obtained as described above must be cor-
rected for temperature. For each 10°F above 80°F, add .004 to the reading. For each 10°F below 80°F, subtract .004
from the reading.
Interpreting the Results of the Hydrometer Test
The approximate state of charge can be determined from the following table:
If the difference between the cells is .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 .050 or more, the battery with the low cell
should be replaced.
