The hydrometer is calibrated at 80° F. Temperature affects the hydrometer
readings. The higher the electrolyte temperature, the higher the specific gravi-
ty reading. The lower the temperature, the lower the specific gravity reading.
Add or subtract four points for each 10° variance from the 80° F chart.
Readings between cells should not vary more than 50 points.
If one cell in a particular battery bank being tested is at a 50% state of
charge while the others are indicating a full charge, charge only that battery
to see if the low cell will come up. At the same time, do not over charge the
“healthy” cells.
If the low cell does not come up after charging, this battery can damage
the rest of the battery bank and should be replaced. An accurate digital volt
meter + - .5% will also give an indicator of the battery’s state of charge.
Another test that can be performed is to place a specific load on the bat-
tery for a predetermined length of time equal to that particular battery’s rat-
ing. This machine is usually an adjustable carbon pile that can vary the load
being applied to the battery(s) while monitoring voltage to see if they will per-
form to their specific rated capacities.
NOTE: See the chart for temperature compensation.
Liquid levels should be even between the cells of the bat-
tery being tested as it will affect the accuracy of the test.
WARNING: Sulfuric acid in the batteries can cause severe
injury or death. Sulfuric acid can cause permanent
damage to eyes, burn skin and eat holes in clothing.
Always wear splash-proof safety goggles when working
around the battery. If the battery electrolyte is splashed
in the eyes, or on skin, immediately flush the affected
area for 15 minutes with large quantities of clean water. In
case of eye contact, seek immediate medical aid. Never add
acid to a battery once the battery has been placed in service.
Doing so may result in hazardous splattering of elec-
trolyte.
