How to Jump-Start a Car Safely
They might find themselves stuck on the side of the road with a car that won’t start. A dead battery is a common issue, accounting for nearly 50% of roadside assistance calls according to the AAA. Whether they forgot to turn off their headlights or have an aging battery, knowing how to jump-start a car safely can be crucial. In this guide, they will learn the steps and precautions needed to get back on the road.
What They Need
- A set of jumper cables
- A working vehicle with a fully charged battery
- Protective gloves (optional but recommended)
- A basic understanding of car battery terminals
Step-by-Step Guide to Jump-Start a Car
- Park the Vehicles: They should park the working vehicle close to the dead car but ensure the two vehicles are not touching. This will make it easier to connect the jumper cables while keeping things safe.
- Prepare the Batteries: Both vehicles should be turned off. They need to locate the car batteries and ensure they know where the positive (+) and negative (-) terminals are.
-
Attach the Jumper Cables:
- Connect one end of the red clamp to the positive terminal on the dead battery.
- Connect the other end of the red clamp to the positive terminal on the working battery.
- Connect one end of the black clamp to the negative terminal on the working battery.
- Lastly, connect the other black clamp to an unpainted metal surface on the dead car, away from the battery to avoid sparks.
- Start the Working Car: They should start the working vehicle and let it idle for a few minutes. This will transfer power to the dead battery.
- Start the Dead Car: After a few minutes, they should try to start the car with the dead battery. If it doesn’t start, allow a few more minutes for charging and try again.
-
Disconnect the Cables: Once the dead car starts, they should carefully disconnect the jumper cables in reverse order:
- Remove the black clamp from the unpainted metal surface.
- Remove the black clamp from the negative terminal on the charged battery.
- Remove the red clamp from the positive terminal on the charged battery.
- Finally, remove the red clamp from the positive terminal on the dead battery.
- Keep the Engine Running: They should keep the revived car running for at least 20-30 minutes or drive it around to recharge the battery further.
Safety Tips
- Inspect Jumper Cables: They should always check their jumper cables for any damage before use to prevent accidents.
- Avoid Cross-Connecting: Ensure they connect the correct battery terminals to avoid damaging the car’s electrical system.
- Stay Alert: They should remain cautious while handling the cables to avoid any sparks or accidental electric shocks.
