7. Record the reading.
G 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. The readings obtained as described above must
be corrected 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 should
be replaced (See Caution Below).
CAUTION
• DO NOT ALLOW BATTERY ACID FROM BATTERY CAPS OR HYDROMETER TO DRIP ONTO THE
FRONT OR REAR BODY. BATTERY ACID WILL CAUSE PERMANENT BLEMISHES. WASH OFF
IMMEDIATELY.
