lRemove the cell plug using a suitable tool.
lAdd distilled water up to the MAX level.
SULPHATION
A battery will be completely discharged if it is left unat-
tended 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 current and higher voltage are observed in the
initial stage of charging sulphated batteries.
A sulphated battery may sometimes be brought back into
service by means of a long, slow charge, 12 hours or more,
followed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.

2. Convert into specific gravity at 20ÉC (68ÉF).
Example:
lWhen electrolyte temperature is 35ÉC (95ÉF) and specific
gravity of electrolyte is 1.230, converted specific gravity at
20ÉC (68ÉF) is 1.240.
lWhen electrolyte temperature is 0ÉC (32ÉF) and specific
gravity of electrolyte is 1.210, converted specific gravity at
20ÉC (68ÉF) is 1.196.

as this may cause a spark.
lBe careful of a rise in battery temperature because a large current flow is required during quick-
charge operation.
If battery temperature rises above 60ÉC (140ÉF), stop charging. Always charge battery when its
