How to Jump-Start a Dead Car Battery.
You turn the key, and instead of the engine starting, you hear a click. Or a slow chewing sound of the starter trying to get the last sips of juice and power the card engine.
Yes, your car battery is dead, again.
If you have time, you could use a car battery charger or even a battery revival charger but those take aong time to get done charging but you don’t have time because everything is last minute here and we don’t plan for things in advance. I had the same problem before so I’m not blaming you but blaming the general us.
Jump-starting a car is easier than you might think, and with a few simple steps, you’ll be back on the road in no time or not depending how it goes. This is everything you need to know to give you a chance for a usable car but we both know, you needed a new car battery since last year but were hoping to delay it as much as possible for obvious monetary reasons.
What You Need
Before you get started, make sure you have these items ready to go:
- Jumper cables: These are the thick, insulated cables with clamps on both ends. They’re essential for transferring power from one battery to another. Your cables or your neighbor’s cables if they are willing to help you.
- A working car: You’ll need another vehicle with a charged battery to provide the jump. That’s your neighbor’s car right there.
- Safety gear: Gloves and safety glasses are a good idea, just in case but you might or might not use them deprnding on your medical insurance plan or even the life insurance specs.
Step 1: Park the Cars Close Together
First, position the working car so it’s close to the car with the dead battery. Make sure the two vehicles aren’t touching, but the jumper cables can easily reach both batteries. Turn off both cars and set the parking brakes.
Ideally both cars are facing each other.
Step 2: Identify the Battery Terminals
Pop the hoods of both cars and locate the batteries. Each battery has two terminals:
- Positive terminal: Marked with a “+” sign, usually red.
- Negative terminal: Marked with a “-” sign, usually black.
At all times you want to be extra careful when handling the red cable unless you have a fire extinguisher nearby – wilhich you should totally have ready to use just in case.
If the red positive wires touch the car metallic parts, you might cause a gigantic short circuit that would start a fireworks show right there in your driveway.
Step 3: Connect the Jumper Cables
This is the most important part, so follow these steps super duper carefully:
- Attach the red clamp to the positive terminal (+) of the dead battery.
- Attach the other red clamp to the positive terminal (+) of the working battery.
- Attach the black clamp to the negative terminal (-) of the working battery.
- Attach the last black clamp to an unpainted metal surface on the dead car (like a bolt or bracket). This acts as a ground and reduces the risk of sparks near the depleted battery.
A lead battery that is low on power juice will most likely release Hydrogen gas and you don’t want the spark and that gas anywhere near each other for real…
Step 4: Start the Working Car
Once the cables are securely connected, start the engine of the working car. Let it run for a few minutes to charge the dead battery.
Step 5: Start the Dead Car
Now, try starting the car with the dead battery. If it doesn’t start right away, wait a few more minutes and try again. Once it starts, let both cars run for a few minutes to ensure the dead battery gets enough charge.
Step 6: Disconnect the Cables
Once the dead car is running, it’s time to remove the jumper cables. Do this in reverse order:
- Remove the black clamp from the grounded metal surface.
- Remove the black clamp from the working battery.
- Remove the red clamp from the working battery.
- Remove the red clamp from the previously dead battery.
Be careful not to let the clamps touch each other while they’re still connected to a battery.
Step 7: Keep the Car Running
After the jump-start, keep the car running for at least 10-30 minutes to allow the battery to recharge. If the battery dies again soon after, it might be time for a replacement or worse the alternator might be going bad and not charging the car battery.
Safety Tips to Keep in Mind
- Always double-check the connections to make sure they’re secure.
- Avoid touching the clamps together or letting them move near metal surfaces.
- If the battery looks damaged, leaking, or swollen, don’t attempt to jump-start it. Call road assistance instead.
Conclusion
Jump-starting a car is a really useful skill that can save you time and money or you can look like the hero one day.
With a bit of practice, you’ll be able to do it when needed. Drive safely and consider getting your battery tested if it dies frequently.
