Does Charging a Battery Mess Up Another Cars Engine Lights?

It is a common misconception that charging a battery can mess up another car’s engine lights. This is not true. In fact, it is perfectly safe to charge a battery from another car. However, there are a few things you should keep in mind when doing so.

Safety First

Before you start charging a battery, it is important to take some safety precautions. First, make sure that the two cars are parked in a well-ventilated area. This will help to prevent the build-up of hydrogen gas, which can be explosive.

Next, make sure that the battery terminals are clean. This will help to ensure a good connection and prevent sparking. Finally, wear gloves and safety glasses when handling the battery.

Connecting the Cables

Once you have taken the necessary safety precautions, you can connect the jumper cables. First, connect the positive terminal of the dead battery to the positive terminal of the good battery. Then, connect the negative terminal of the dead battery to the negative terminal of the good battery.

It is important to connect the cables in this order. If you connect the negative terminal of the dead battery to the positive terminal of the good battery, you could create a spark that could ignite the hydrogen gas.

Starting the Cars

Once the cables are connected, you can start the car with the good battery. Let the car run for a few minutes to charge the dead battery. Once the dead battery is charged, you can start the car with the dead battery.

Once both cars are running, you can disconnect the jumper cables. Be sure to disconnect the cables in the reverse order of how you connected them. This will help to prevent sparking.

Conclusion

As you can see, charging a battery from another car is a simple and safe procedure. Just be sure to follow the safety precautions and you will be able to get your car started in no time.
