How to Charge a Car Battery From Another Car: A Step-by-Step Guide
Having a dead car battery can be a frustrating experience, especially when you have somewhere important to be. However, with a little help from another car, you can easily jump-start your vehicle and get back on the road. Here’s a step-by-step guide on how to charge a car battery from another car in the United Kingdom.
Step 1: Find a suitable vehicle – Look for another car with a similar voltage system (usually 12 volts) and park it close to your vehicle.
Step 2: Ensure safety – Both cars should be turned off, and it’s crucial to wear safety gloves and goggles to protect yourself from any potential sparks or hazardous chemicals.
Step 3: Connect the jumper cables – Open both car hoods and locate the batteries. Attach one end of the red jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the working battery. Then, connect one end of the black jumper cable to the negative terminal of the working battery and the other end to an unpainted metal surface on the dead car.
Step 4: Start the working vehicle – Start the working car and let it run for a few minutes to charge the dead battery.
Step 5: Start the dead vehicle – Attempt to start the dead car. If it doesn’t start, wait a few more minutes and try again. Once the dead car starts, leave both vehicles running for at least 5-10 minutes to allow the dead battery to charge further.
Step 6: Disconnect the jumper cables – In reverse order, remove the black jumper cable from the unpainted metal surface, then from the negative terminal of the working battery. Finally, disconnect the red jumper cable from the positive terminal of the working battery, and then from the positive terminal of the dead battery.
