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.
