TESTING
Specific Gravity
Note: The battery must be fully charged before
performing this test.
The specific gravity of a cell is an indication of the actual
state of charge of the cell. A fully charged cell should have
a reading of 1275 to 1300 (see the illustration below). A
discharged cell will read 1100. Ideally, all cells in a battery
will have the same reading. Any cells in a battery that
vary by more than 25 points may be an indication of a
bad or weak cell.
Clean the battery. Refer to Cleaning section for
information on cleaning the battery.
Using part number 77-200-00 hydrometer or equivalent
graduated type hydrometer, test and record the specific
gravity of each cell in the battery.
Use the highest reading to compare to all other cells. Any
cell or cells that are more than 25 points less than the
highest reading should be suspected as being a bad cell.
If, after charging, none of the cells exceed a hydrometer
reading of 1250 then there may be a fault in the charging
system. If the charging system checks OK then the
battery pack is no longer accepting a charge and should
be replaced.
It may be possible to replace Individual cells in industrial
batteries. Contact the battery manufacturer for details.

WARNING
DO NOT attempt to test the specific gravity of a sealed
battery. Removing the caps of a sealed battery will
damage the battery resulting in premature failure.
