There’s a particular sigh of resignation that comes with turning the key and hearing nothing but a faint click, or worse, complete silence. A dead car battery can happen to anyone, often at the most inconvenient times. While it can feel like a major setback, knowing how to properly jump start a car is a simple and essential skill that can get you back on the road in minutes.
With a good Samaritan, a set of jumper cables, and a basic understanding of the steps, you can solve this common problem safely and effectively. The key is to follow the process carefully to avoid damaging your vehicle’s sensitive electrical system.
The Essential Gear You’ll Need
Before you begin, you’ll need two things: a working vehicle with a healthy battery and a set of jumper cables. It’s wise to keep a good quality pair in your trunk at all times. Look for cables that are thick, with heavy-duty clamps, as they will conduct electricity more effectively than thin, cheaply-made ones.
A Step-by-Step Guide on How to Properly Jump Start a Car
Park the working car close to the one with the dead battery, but ensure they are not touching. Turn both engines off and set the parking brakes. Pop the hoods on both vehicles and locate the batteries.
Now, it’s time to connect the cables in this specific order:
- Connect one RED clamp to the POSITIVE (+) terminal of the dead battery.
- Connect the other RED clamp to the POSITIVE (+) terminal of the good battery.
- Connect one BLACK clamp to the NEGATIVE (-) terminal of the good battery.
- Connect the final BLACK clamp to an UNPAINTED METAL SURFACE on the dead car’s engine block or chassis. This is a crucial safety step.
Bringing Your Battery Back to Life
Start the engine of the working car and let it run for a few minutes. Then, try to start the car with the dead battery. If it starts, great! If it doesn’t, wait a few more minutes and try again. Once your car is running, carefully disconnect the jumper cables in the reverse order you connected them: black from the ground on the rescued car, black from the good battery, red from the good battery, and finally, red from the once-dead battery.
Important Safety Tips to Remember
Always double-check the positive and negative terminals before connecting the clamps. A wrong connection can cause serious damage. Never let the red and black clamps touch each other once any are connected to a battery. Keep loose clothing and hair away from engine components. If the dead battery looks cracked, is leaking, or smells strongly of sulfur, do not attempt a jump start; it needs professional replacement.
With the cables safely stowed away, keep your newly-running car going for at least 15-20 minutes to allow the alternator to recharge the battery. While a jump start is a fantastic fix for a momentary lapse, if your battery dies repeatedly, it’s likely time for a new one. Knowing this simple procedure empowers you to handle a common roadside hiccup with confidence.
