Jump-Starting a Car Battery: Do’s and Don’ts

A dead car battery can bring your day to a standstill, but jump-starting isn’t as simple as it seems. HandyMan Goa shares expert tips to help you jump-start safely—and avoid common mistakes that can damage your car or risk your safety.

Do’s: Safe Jump-Start Steps

• Park both cars on level ground, away from traffic, and switch off both engines. Ensure handbrakes are engaged, doors are shut, and both vehicles are NOT touching each other.
• Check batteries for leaks, cracks, or corrosion. If damaged, don’t attempt a jump-start—call a professional instead.
• Identify battery terminals (Red = Positive [+], Black = Negative [–]). Wipe terminals clean for good contact.
• Connect jump cables in this order:
  1. Red clamp to the dead battery’s positive terminal (+).
  2. Red clamp to the “booster” battery’s positive terminal (+).
  3. Black clamp to booster car’s negative terminal (–).
  4. Black clamp to an unpainted metal part (engine block) away from the dead battery.
• Start the booster car first, let it run 2–3 minutes. Try starting the dead car; if it doesn’t start, wait a few more minutes and retry.
• Remove cables in reverse order: First, black clamp from engine block, second from booster battery; then red clamps from both batteries.
• Let your revived car run for 15–30 minutes, or drive to recharge the battery.

Don’ts: Mistakes to Avoid

• Never jump-start a leaking, frozen, or physically damaged battery. This risks explosions, acid burns, and serious injury—call for help instead.
• Don’t let cables touch each other or any metal surfaces. This causes dangerous sparks.
• Don’t connect the black cable to the negative terminal of the dead battery. Go for the engine block or chassis instead for safety.
• Don’t remove jump cables while engines are running. This can damage sensitive electronics in modern vehicles.
• Avoid jump-starting near open flames, dangling jewelry, or wet conditions. Batteries emit flammable gases, so keep sparks, cigarettes, and metal away.
• Don’t keep trying if your car won’t start after a few attempts. The battery may need replacement or professional diagnosis.
