CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.
Remove the cell plug using a suitable tool.
Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.
