What to Do When the Car Battery Won't Start?

Here are the solutions when the car battery won't start: 1. Push Start Method: Push the car to a certain speed, then shift the gear lever into gear and quickly release the clutch pedal while pressing the accelerator. Once the engine starts, quickly depress the clutch pedal and control the throttle to prevent the engine from stalling, then slowly pull over to park. 2. Towing Start Method: Start slowly when towing. The driver of the front car should pay attention to the movement of the rear car, and the driver of the rear car should signal the front car promptly after starting. Both cars should slowly pull over to the roadside to park, which is relatively safe and effective, although it may take some time. 3. Jump Start Method: First, find another car with a working battery and a set of jumper cables. Open the hood to locate the other car's battery, then connect the two car batteries using the jumper cables.
