Getting caught out by a dead car battery can be frustrating, seeing many motorists stranded in less-than-ideal places.
One of the most common ways to get a car back on the road is through the use of jump leads to jumpstart the battery.
However, while this method is widely known, many are unaware of how to do this.
How to jumpstart a car battery using jump leads
Here is a step-by-step guide on how to jumpstart a car using jumper cables, according to the experts over at the AA.
Find another car
To jump-start your car, you will need the help of another driver who's happy to lend a hand. Their car must have a fully charged battery with the same voltage as yours (usually 12 volts).
You should then park both cars so that their batteries are within easy reach of each other (without them actually touching). Handbrakes should be on and ignitions off.
Connect the red jumper cable
You should then use the red jump lead to connect the working battery's positive (+) terminal to the one on the flat battery.
The ends of the red and black cables should never touch as this could create a spark.
Connect the black jumper cable
Next, you should use the black cable to connect the working battery's negative (-) terminal to an earthing point (unpainted metal on the engine block or chassis) well away from the flat battery and fuel system.
Start the other car
Keep both engines off for three minutes before starting the working car's engine, letting it run for a minute.

Start your car
After this, you should start the engine in the car with a flat battery.
Let both cars run
Both cars should be left to run for around 10 minutes.
Disconnect and restart your car
The next step involves turning both engines off and carefully disconnecting the leads in the reverse order to the way they were connected (remove the black lead from your car first and finish with the red lead from the other car).
The leads should not touch each other or either car when you remove them.
Once you have followed these instructions, try starting the ignition to see if the car starts up.
What to do if this does not work

Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
