• 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.

BATTERY

CHARGING THE BATTERY

CAUTION:

• Never “quick charge” a fully discharged battery.

• Keep the battery away from open flame while it is being charged.

• When connecting the charger, connect the leads first, then turn on the charger. Never turn on the

charger first, as this may cause a spark.

• If battery electrolyte temperature rises above 55

°C (131 °F), stop charging. Always charge battery at

a temperature below 55

°C (131 °F).

Charging Rates

Do not charge at more than 50 ampere rate.

NOTE:

The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-

cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps

indicated above refer to initial charge rate.

• If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be replaced.

TROUBLE DIAGNOSIS WITH BATTERY SERVICE CENTER

For battery testing, use Battery Service Center (J-48087). For details and operating instructions, refer to Tech-

nical Service Bulletin and/or Battery Service Center User Guide.
