BATTERY
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. Convert into specific gravity at 20°C (68°F).
Example: When electrolyte temperature is 35°C (95°F) and specific gravity of
electrolyte is 1.230, converted specific gravity at 20°C (68°F) is
1.240.
When electrolyte temperature is 0°C (32°F) and specific gravity of
electrolyte is 1.210, converted specific gravity at 20°C (68°F) is
1.196.
