Battery Function on the Vehicle

Battery Function on the Vehicle

The battery is one of the parts of the electrical system that exists in vehicles, both in motorcycle vehicles and vehicles in automobile vehicles.

Battery is a device used to store electrical energy sources through electro -chemical process, that is, from a chemical process converted into electrical energy (during the emptying process) and vice versa from electrical energy converted into a chemical process (during the charging process).

The current that comes from the battery is a direct current or DC current (Alternating Current) . While the battery voltage used is 12 volts.

The battery has a very important function for electricity in the vehicle, the function of the battery, among others:

At the time the engine is off

At the time of the engine, this battery serves as a source of electrical power that serves to turn on the electrical system in the vehicle, such as sein lights (turn signal lights), horns (horns), indicators on the dashboard, city lights, headlights and others. so on.

When the engine is still not running, the battery is the only source of electricity used, because at this time the alternator on the vehicle is not working.

At the time of starting the engine

When performing a starter using electric starter, the battery is also the only source of electricity used to start or run the starter motor.

When the machine is on

By the time the engine is on, the alternator on the vehicle is working, so the battery is no longer the main source of electrical energy. But when the engine is running the battery still has a function as a voltage stabilizer of the alternator.

Given that the work of the alternator is less stable and depends on the rotation of the alternator, although the alternator is equipped with a regulator but still requires a battery as a voltage stabilizer which will later flow to the electrical system on the vehicle.

On the battery used on the vehicle, the construction can be seen in the picture below:

Battery box

The battery box serves as a barrier to hold electrolytes and other elements. The space inside the battery box is divided into several sections according to the number of cells in the battery. On the battery box there is also a line that shows the amount of electrolyte, namely the upper lever and lower level limits (on wet batteries).

Electrolyte battery

The electrolyte in the battery is a mixture of water (H2O) with sulfuric acid (SO4), the composition of the mixture is water (H2O) with a percentage of approximately 64% and sulfuric acid with a percentage of approximately 36%. From the comparison of the mixture, an electrolyte weight of 1,270 will be produced. New Technology from RV battery is a good from your vehicle

Close the battery and ventilation holes

The battery is equipped with a battery cover that works to prevent the accumulation of electrolyte fluid on the battery box. In addition, the battery cover is also equipped with ventilation holes. This ventilation hole serves as a place for the release of hydrogen gas from chemical processes that occur in the battery.


The separator or blocker  on the battery serves to separate each cell on the battery.

Battery cell

The battery consists of several cells, on the battery worn on the vehicle there are 6 cells. One cell on the battery produces approximately a voltage of 2.1 Volts, the battery cells are arranged in series so that when there are 6 cells then the battery produces a voltage of 12.6 Volts.

These cells consist of a positive plate and a negative plate. These cells are made of lead metal plates that have pores, in order to facilitate the occurrence of chemical processes in the pores of the cells.
