Part: Battery

The car battery is essential for starting the engine; you can consider it the second heart of the car. Today, let's look at three important things to know about it. The first thing is about removing and installing the battery. When you decide to replace the car battery, always remember to disconnect the negative terminal connected to the body first, and only then disconnect the positive terminal connected to the car's electrical components. After disconnecting both terminals, you can proceed with the installation by connecting the positive terminal first, as it may still hold a charge, so be careful of possible short circuits. Once the battery is connected, you can close the bonnet. The second thing to know is the main specifications of each battery, which are the voltage measured in volts and the capacity in ampere-hours.
