How to Jumpstart a Car Without Jump Leads in the United Kingdom

Discovering that your car’s battery is dead can be a frustrating experience, especially when you don’t have jump leads available to revive it. However, there are alternative methods to jumpstart your car without relying on jump leads. Here’s a step-by-step guide to help you get back on the road in the United Kingdom.

Firstly, locate a vehicle with a similar voltage battery to yours. This is crucial as you’ll need to transfer power from their battery to yours. Once you find a suitable car, park it close to your vehicle, ensuring both engines are turned off.

Next, open the bonnet (hood) of both cars and locate their batteries. Identify the positive and negative terminals on both batteries. The positive terminal is usually marked with a plus (+) sign, while the negative terminal is marked with a minus (-) sign.

Connect a red wire or cable to the positive terminal of the working car’s battery and then attach the other end to your dead car’s positive terminal. Take a black wire or cable and connect one end to the negative terminal of the working car’s battery. However, instead of connecting the other end to your car’s negative terminal, attach it to an unpainted metal surface within the engine bay of your dead car. This will act as a ground.

Now, start the engine of the working car and allow it to run for a few minutes. This will transfer power to your dead car’s battery. Once enough time has passed, attempt to start your car. If successful, let it run for a while before disconnecting the cables in the reverse order they were connected.
