CHECKING BATTERY SPECIFIC GRAVITY

Use a hydrometer to check the battery specific

gravity.

CHECKING GRAVITY

A. Hydrometer

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.

BATTERY CONDITION

1.265 100% CHARGED

1.225 75% CHARGED

1.190 50% CHARGED

1.155 25% CHARGED

1.120 DISCHARGED

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°): 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).
