Getting stuck with a flat battery can happen when you least expect it. Maybe you left your headlights on, or the battery is just old. Either way, it’s not a great feeling—especially if you’re far from home. Fortunately, learning how to jumpstart a car gives you the tools to deal with the problem right away.
You don’t need advanced skills or expensive tools. With a good set of jumper cables and the right approach, you can get your vehicle running again in minutes. This guide will show you the safest and simplest way to do it—even if it’s your first time.
What Happens When A Car Battery Dies?
A car battery might die for many reasons. You may have left your lights on overnight, the weather could be cold, or the battery might be old and near the end of its life. Whatever the reason, when your engine won’t turn over and the dash lights seem dim or off, chances are you’ve got a dead car battery.
In most cases, you won’t need to replace it immediately. A battery jump start is often enough to get it running again—especially if the battery was working fine before the incident.

How To Jumpstart A Car Safely?
A flat battery can bring your day to a halt, whether you’re parked at home or stranded somewhere unexpected. Fortunately, jumpstarting a car is a straightforward process that can get you moving again with just a set of jumper cables and another vehicle with a healthy battery. Knowing this simple process can save time, avoid towing fees, and help you regain control of the situation without delay.
Learning how to jumpstart a car is an important skill. You just need another vehicle with a working battery and a set of car jumper cables.
Step 1: Park the Cars Close
Bring the working car near the one with the flat battery. Make sure both vehicles are turned off. The cars should not touch each other.
Step 2: Find the Battery
Lift the bonnet on both vehicles. Locate the battery terminals—positive is usually marked with a “+” and negative with a “-”.
Step 3: Connect the Jump Start Cables
Take your jump start cables and connect them in this order:
1. Red clip to the car battery jump terminal on the dead car (positive +)
2. Red clip to the working car’s positive (+)
3. Black clip to the working car’s negative (-)
4. Black clip to an unpainted metal part of the dead car (not the battery)
This method avoids sparks and reduces risk.
Step 4: Start the Working Car
Turn on the car with a good battery. Let it run for 2–3 minutes.
Step 5: Try to Start the Dead Car
Attempt to start the dead vehicle. If it doesn’t start, wait a bit longer and try again. If it still won’t start, the battery may be too far gone.
Step 6: Remove the Cables in Reverse
Once the car starts, you should carefully remove the cables in reverse order:
1. Remove the black clamp from the grounded metal
2. Remove the black clamp from the working battery
3. Remove the red clamp from the working battery
4. Remove the red clamp from the battery that was previously dead
Let the engine run for 15–30 minutes before switching off. This helps the battery recharge a bit.
What To Do After A Successful Jumpstart?
After your car has started, it’s important not to turn it off right away. Keep the engine running for at least half an hour if you can. This allows your battery to be recharged using the vehicle’s alternator. Try to take a short drive instead of idling, as this will help the charging process.
While you’re driving, turn off unnecessary electrical systems like the radio or air conditioning. This helps the battery recover more quickly. Once you’re home or at your destination, test the car again later in the day to see if it starts smoothly.
If you need to jump start again within 24 hours, your battery might not be holding a charge. That could be a sign that service for a car battery replacement in Perth is needed.
