Fig. 5 ADDITIONAL CHARGE (Standard charge)
CAUTION:
lDo not use standard charge method on a battery whose specific gravity is less than 1.100.
lSet charging current to value specified in Fig. 4. If charger is not capable of producing specified
current value, set its charging current as close to that value as possible.
lKeep battery away from open flame while it is being charged.
lWhen connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.
lIf battery temperature rises above 60°C(140°F), stop charging. Always charge battery when its
temperature is below 60°C (140°F).
