CHARGING THE BATTERY
NGSC0003S04
CAUTION:
¼ Do not “quick charge” a fully discharged battery.
¼ Keep the battery away from open flame while it is being
charged.
¼ 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.
¼ If battery electrolyte temperature rises above 60°C (140°F),
stop charging. Always charge battery at a temperature
below 60°C (140°F).
Charging Rates
NGSC0003S0401
Amps Time
50 1 hour
25 2 hours
10 5 hours
5 10 hours
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 indicates 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.
¼ If, after charging, the specific gravity of any two cells varies
more than .050, the battery should be replaced.
