Test Procedure 2, Continued:
7. Record the reading.
8. Return the electrolyte to the cell from which it was taken. Replace vent cap.
9. Repeat steps 2-8 on all cells.
Hydrometer Calibration
Most hydrometers are calibrated to read correctly at 80 °F (27 °C). The readings obtained as described
above must be corrected for temperature. For each 10 °F (5.6 °C) above 80 °F (27 °C), add 0.004 to the
reading. For each 10 °F (5.6 °C) below 80°F (27 °C), subtract 0.004 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 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
should be replaced.
