Preparing to Use the Car Battery Charger. Before attaching the battery charger, turn the car off and open the bonnet. Locate the car battery terminals and clean them with baking soda and water. If there is much corrosion on the terminals, scrub it off using a wire brush. Take care to wear safety glasses while doing this. Check the amount of water in each cell. If your car battery is dead, your can safely connect it to a charger and get your car running again. Step 1: Protect yourself. Wear protective clothing and eye protection. Remove any jewelry, never put your face near the battery, and keep the charger as far away from the battery as the cables permit. The positive charger clip will be red and the negative charger clip will be black. Be sure to connect the positive clip first. Step 5: Connect the negative clip. Connect the negative charger clip to the car's frame or engine block as far away from battery as the clip's cable will allow. Always connect the negative clip to a heavy-gauge metal part of the frame or engine block -- never the carburetor, fuel lines, or sheet-metal body parts If your battery is grounded on the negative side, as most are, you should first attach the positive cable to the positive battery terminal, then the negative cable to the frame of the car. If it is grounded on the positive side, attach the negative cable to the negative terminal and the positive cable to the frame. Before using the charger, make sure it is plugged in to an outlet that is grounded. Car batteries are grounded to the frame of the car to reduce the risk of a spark occurring near the battery when connecting to a charger, which could cause an explosion. 1 Connect the positive (usually red) charger cable to the positive (+) battery terminal and the negative (usually black) cable to the negative (-) battery terminal. 2  Decide whether you want to charge the battery slowly (trickle charge) or quickly. 1 Use the correct charger for your particular car battery. 2  Check the car owner's manual for information (or ask your car dealer or trusted auto mechanic). 3  Read the charger manual and make sure you understand how the charger works and what precautions are necessary. 4  Pay close attention to all the warnings.
