FLUID LEVEL AND SPECIFIC GRAVITY CHECK
1.
Inspect whether or not the battery fluid is between the
UPPER LEVEL and LOWER LEVEL marks.
2.
Use a hydrometer and thermometer to check the specific
gravity of the battery fluid.
Standard value: 1.220– 1.290 [20

The specific gravity of the battery fluid varies with the
temperature, so use the following formula to calculate
the specific gravity for 20

C. Use the calculated value
to determine whether or not the specific gravity is
satisfactory.
