Test Procedure 1 – Battery, Continued:
7. Record the reading.
8. Return the electrolyte to the cell from which it was taken. Replace vent cap.
9. Repeat steps 2 through 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 by referring to 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.
Voltage Test
1. Place the red (+) probe of a multimeter set at Volts DC, 20 volt range, on the positive (+) cable and place
the black (–) probe on the negative (–) post of the battery and take a voltage reading. If it shows less than
12.4 volts, or if the lowest specific gravity reading from the hydrometer test is less than 1.225, recharge
the battery. If battery voltage is greater than 12.4 volts and specific gravity is greater than 1.225, the prob-
lem is not with the battery. If the battery does not reach 12.4 volts, or if the specific gravity of a cell is still
less than 1.225 after charging, replace the battery.
