Does a car need a new battery if it won't start due to a dead battery?

Solutions for a dead battery preventing the car from starting: Use the jump-start method. 1. Position the two cars 'face to face' (as close as possible to each other), then turn off the rescue vehicle to avoid excessive current damaging the battery cables. Ensure all electrical switches in the rescued vehicle are turned off, open both engine compartments, and locate the positive and negative terminals of both batteries (red '+' for positive, black '-' for negative). 2. The correct way to connect the jumper cables is: First, connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle's battery; then connect the negative terminal of the rescue vehicle's battery to a metal part of the dead vehicle's body. Black is the negative cable, red is the positive cable. 3. After ensuring the cables are correctly and securely connected, start the rescue vehicle; let it run for a few minutes to charge the dead battery. Then attempt to start the dead vehicle. 4. If the dead vehicle still won't start, you can slightly rev the rescue vehicle's engine before trying to start the dead vehicle again. Do not force-start the vehicle, and pay attention to the starting intervals. If it still doesn't start, consider whether the jumper cables are too thin, resulting in insufficient current.
