• 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 specific 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 observed 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 electrolyte. 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.

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 (Standard Charge)

Charging Rates (Quick Charge)

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.
