2.8

CAUSING PERSONAL INjURY AND DAMAGE. 

The charger is not intended to supply power to a low-voltage electrical system other than applica-

tions using rechargeable, lead-acid type batteries. Do not use battery charger for charging dry-cell 

batteries commonly used with home appliances. These batteries may burst and cause personal 

injury and property damage.

2.9  NEVER charge a frozen battery, thaw it out first. Charging will then be safer and more efficient.

3.  If necessary to remove battery from vehicle to charge, always remove grounded terminal from 

battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.

3.2  Be sure area around battery is well ventilated while battery is being charged. Gas can be force-

fully blown away by using a piece of cardboard or other nonmetallic material as a fan.

3.3  Clean battery terminals. Be careful to keep corrosion from coming into contact with your eyes.

3.4  Add distilled water in each cell until battery acid reaches level specified by manufacturer. This 

helps purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow 

the manufacturer’s recharging instructions 

3.5  Study all battery manufacturer’s specific precautions such as removing or not removing cell caps 

while charging and recommended rates of charge.

3.6  Determine voltage of battery by referring to car owner’s manual and make sure that the output 

voltage selector switch is set at correct voltage. If charger has adjustable charge rate, charge 

battery initially at lowest rate. If charger has only one voltage, verify that battery voltage matches 

voltage of charger. 

For a charger not having an output voltage selector switch, determine voltage of battery by refer-

ring to car owner’s manual and make sure it matches output rating of battery charger.

4.  Charger must be grounded to reduce risk of electric shock. Charger is equipped with an elec-

tric cord having an equipment grounding conductor and a grounding plug. The plug must be 

plugged into an outlet that is properly installed and grounded in accordance with all local codes 

and ordinances.
