Charge the car battery

A tweezers and a charged battery of another car, is what we need to charge the car battery easily.

If you have run out of battery in the middle of a journey or before leaving home, you should not be alarmed as you can charge it with the step-by-step guide below, where we explain how to easily charge the car battery.

Having a problem with the car battery is something that can happen to all of us, and although the ideal is to go to a mechanic to check from time to time, it can happen that we suddenly find ourselves with the discharged battery so that we will have to follow some steps that are very specific to be able to charge it, which involve the use of clamps to connect to the battery and also a car that has its battery charged.

Steps to easily charge the car battery

To connect a discharged battery to that of a working vehicle, only one electrical cable with a diameter of at least 16 mm is required. A 25 mm electric cable is recommended for cars with large displacement.

The vehicle battery must be connected to a battery of the same voltage. Most vehicles operate at a voltage of 12 V. Only a few old cars have a voltage of 6 V. In any case, consult the vehicle’s instructions for use.

To connect the batteries and be able to charge the one that is discharged, we have to place the two cars on a flat surface and block them. The moving car and the damaged vehicle must not touch each other to avoid the risk of a short circuit.

In many modern cars, the battery is no longer in the engine compartment, but negative and positive poles can still be easily identified. If not, refer to the car’s operating instructions. The engine of both vehicles must be turned off.

Fasten the power cord only to insulated plastic handles.

With the use of gloves and safety glasses, you have to connect the red wire to the positive pole, the black wire to the negative pole.

First connect the red cable clamp to the positive pole of the car in operation, then the other end of the red cable to the positive pole of the vehicle without battery. Then, attach the black clamp to the negative pole of the operating battery.

On the other hand, never connect the other end of the black cable to the negative pole, but to a point on the body of the unloaded vehicle. Choose a solid, unpainted metal part in the engine compartment, e.g. the engine.

It is not recommended to connect the electric cable directly to the negative pole of the vehicle without battery. Sparks may be emitted and the battery may be damaged. In old lead-acid batteries, acid can leak and be a source of risk. Explosive gas may form.

Start the engine of the vehicle in operation first and only after the decomposed vehicle. If the intervention has been successful, you should be able to switch on some electrical equipment in the vehicle without a battery, such as headlights.

To avoid voltage spikes when disconnecting the terminals from the poles, the terminals should be disconnected in reverse order.

If the car does not start immediately, wait at least one minute before restarting it. If the subsequent attempt is unsuccessful, the power cord may be defective or unsuitable. Try again with an intact and proper cable.
