care, such as undercharging and over-watering, and possibly even locate a bad or
weak battery. The following steps outline how to properly perform routine voltage
and specific gravity testing on batteries.
Specific Gravity Test (Flooded batteries only)
1. Do not add water.
2. Fill and drain the hydrometer 2 to 4 times before pulling out a sample.
3. There should be enough sample electrolyte in the hydrometer to com-
pletely support the float.
4. Take a reading, record, and return the electrolyte back to the cell.
5. To check another cell, repeat the 3 steps above.
6. Check all cells in the battery.
7. Replace the vent caps and wipe off any electrolyte that might have been
spilled.
8. Correct the readings to 80˚ F: Add .004 to readings for every 10˚ above 80˚
F, Subtract .004 for every 10˚ below 80˚ F.
9. Compare the readings.
10. Check the state of charge using Table 1.
The readings should be at or above the factory specification of 1.277 +/- .007. If any
specific gravity readings register low, then follow the steps below.
1. Check and record voltage level(s).
2. Put battery(s) on a complete charge.
3. Take specific gravity readings again.
