BATTERY CHARGING
Safety Precautions
Never charge a battery without first reviewing the in-
structions for the charger being used. In addition to the
manufacturer’s instructions, follow these general safety
precautions:
● Always wear proper eye, face and hand protection.
●
Always charge batteries in a well-ventilated area.
●
Turn the charger “OFF” before connecting the leads
to the battery to avoid dangerous sparks.
●
Never try to charge a visibly damaged or frozen bat-
tery.
● Connect the charger leads to the battery; red posi-
tive (+) lead to the positive (+) terminal and black
negative (–) lead to the negative (–) terminal. If the
battery is still in the vehicle, connect the negative
lead to the chassis ground. Be sure that the ignition
and all electrical accessories are turned off.
●
Make sure that the charger leads to the battery are
not broken, frayed or loose.
●
If the battery becomes hot, or if violent gassing or
spewing of electrolyte occurs, reduce the charging
rate or turn off the charger temporarily.
●
Always turn the charger “OFF” before removing
charger leads from the battery to avoid dangerous
sparks.
