Step Park the Cars in a Safe Location

Position the vehicles so that their batteries are as close to each other as possible without touching them.

Step Open the Hoods and Locate the Batteries

Pop open the hoods and identify the battery locations in both cars.

Step Identify Positive and Negative Terminals

“Find the positive (+) and negative (-) terminals on each battery.”

Step Connecting the Jumper Cables

“Connect the jumper cables in the specified sequence:”

  • “Join one end of the red cable to the positive terminal of the dead battery.”
  • “Secure the opposite end of the red cable to the positive terminal of the charged battery.”
  • “Attach one end of the black cable to the negative terminal of the charged battery.”
  • “Fasten the other end of the black cable to an unpainted metal surface on the engine of the dead car.”

Step Starting the Functioning Car

“Begin the car with the fully charged battery and allow it to run for a few minutes.”

Step Starting the Dead Car

Attempt to start the dead car.

“If it doesn’t start, wait for a few additional minutes and then attempt again.”

Step Safely Disconnecting the Cables

Once the dead car starts, carefully reverse the cable connection process.

After a Successful Jump-Start

After successfully jump-starting your car, follow these steps:

Running the Revived Car

Keep the revived car running for at least 15 minutes to recharge the battery.

Checking the Charging System

Consider having the charging system inspected by a professional to ensure it’s functioning properly.

Preventing Car Battery Drain in Rainy Conditions

To avoid future battery issues during rainy weather:
