Nissan Terrano r20e. Instruction — part 422
I
Remove the cell plug using a suitable tool.
I
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 volt-
age and current when charging it. As shown in the figure, less
current 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:
I
When electrolyte temperature is 35°C (95°F) and specific grav-
ity of electrolyte is 1.230, converted specific gravity at 20°C
(68°F) is 1.240.
I
When electrolyte temperature is 0°C (32°F) and specific grav-
ity of electrolyte is 1.210, converted specific gravity at 20°C
(68°F) is 1.196.
