Battery Charging

Safety Precautions

Never charge a battery without first reviewing the instructions 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 battery.

• Connect the charger leads to the battery; red positive (+) lead to the positive (+) battery terminal and black negative (-) lead to the negative (-) battery terminal. If the battery is still in the vehicle, connect the negative lead to the chassis ground. Be sure the ignition and all electrical accessories are turned off.

• Make sure 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 charger "OFF" before removing charger leads from the battery to avoid dangerous sparks.

Charging Battery

Charge the battery if any of the following conditions exist:

• The vehicle lights appear dim.

• The electric starter sounds weak.

• The battery has not been used for an extended period of time.
