BATTERY
• 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. Less current and higher voltage are
observed in the initial stage of charging sulfated batteries, as
shown.
A sulfated 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. Use the following chart to correct your hydrometer reading
according to electrolyte temperature.

CHARGING THE BATTERY
CAUTION:
• Do not “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. Do not turn on the
charger first, as this may cause a spark.
• If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Alw ays 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 norma lly 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.
