Checking Battery Specific Gravity
Use a hydrometer to check the battery specific gravity.
CHECKING GRAVITY
a. Hydrometer Battery
b. Battery
NOTE: Do not take readings immediately after adding
distilled water, if the water and acid are not
thoroughly mixed, the reading may not be accurate.
Check the hydrometer readings against this chart.
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F (27°C),
the reading must be temperature corrected.
To find the corrected specific gravity reading when the
temperature of the battery electrolyte is other than 80°F
(27°C): Add (+) to the specific gravity reading 0.004 (4
points), for each 10°F (6°C) above 80° (27°C). Subtract
(-) from the specific reading 0.004 (4 points), for each
10°F (6°C) below 80°F (27°C).
