• Remove the cell plug using a suitable tool.
• Add distilled water up to the MAX level.
SULFATION
• A battery will be completely discharged if it is left unattended
for a long time and the specifi c gravity will become less than
1.100. This may result in sulfation on the cell plates.
• To determine if a battery has been “sulfated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are ob served in the initial stage of
charging sulfated batteries.
• A sulfated 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
NOTE:
Check the charge condition of the battery.
Periodically check the specific gravity of the electr olyte. Keep a close check on charge condition to prevent
over-discharge.
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord- ing to electrolyte temperature.
