- 1). Open the hood of the car. Remove plastic covers from the top of the car battery's posts if there are any. Inspect the battery posts for corrosion, which will appear white and crusty. You'll need to remove the corrosion prior to jump starting the battery.
- 2). Clean corrosion from the battery posts. Mix 1 cup water with 1/4 cup baking soda. Pour mixture over posts. The corrosion will bubble and turn a darker color. Rinse with remaining water. Wipe dry with a towel.
- 3). Apply lubricating oil, such as WD-40, to the battery posts to prevent future corrosion. You can purchase lubricating oil at supermarkets, hardware stores and auto parts stores.
- 1). Turn all electrical components inside the vehicle off, including the radio, headlamps, heater and air conditioner.
- 2). Ensure the vehicle transmission is in the park or 'P' position. Set the vehicle parking brake.
- 3). Connect one red jumper cable end to the positive (+) battery post on the dead battery. Connect the other red jumper cable end to the positive post on a fully charged car battery, also known as a booster battery.
- 4). Connect one black jumper cable end to the negative (-) post on the booster battery and then connect the other black jumper cable end to the negative post on the dead car battery.
- 5). Start the engine of the car with the booster battery and allow it to run at a fast idle.
- 6). Start the vehicle with the dead car battery. If the motor does not respond, wait five minutes and retry. Once the vehicle engine starts, allow it to run for two to three minutes.
- 7). Disconnect the (black) negative jumper cable end from the jump-started battery, then disconnect the negative cable end from the booster battery.
- 8). Disconnect the (red) positive jumper cable end from the jump-started battery, then disconnect the positive cable end from the booster battery.
- 9). Drive the jump-started vehicle to a service station and have the battery professionally inspected.
