5. When the float rises off the bottom, adjust the electrolyte level so that the float rides free of the bottom but does not
strike the bottom of the rubber bulb. Remove the hydrometer from the cell and release the pressure from the bulb.
6. Hold the hydrometer vertically, ensuring that the float is not contacting the sides of the glass tube. Hold the
hydrometer at eye level and read the scale at the level of electrolyte
(Figure 19-7, Page 19-13) .
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:
SPECIFIC GRAVITY (TEMPERATURE CORRECTED)
APPROXIMATE
STATE OF CHARGE
1.250 to 1.280 100%
1.220 to 1.240 75%
1.190 to 1.210 50%
1.160 to 1.180 25%
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
Take a voltage reading with a multimeter set to 20 VDC by placing the red (+) probe on the positive (+) battery post and
the black (–) probe on the negative (–) battery post. 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 problem 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.
