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_C]
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.
