How to check your car battery

The car battery is one of the parts of the car and it is the most important part of it because it is responsible for the movement, where the battery to run the engine of the car through a process called the internal combustion of fuel, whether this fuel gasoline or diesel. As well as some newly-created electric vehicles.

In this article, which is provided by the Wejdan Driving Company, we explain in detail how to check the car battery and what signs indicate a battery failure.

Car battery components

The vehicle battery consists of a set of positive and negative panels connected in a row and their number according to the voltage of the battery.

For example, the six-volt car battery consists of three columns of voltage of each column of 2 volts and if the total voltage of the 12 volt battery consists of six voltage poles.

The positive and negative compounds are immersed in an electronic solution in a container that is not affected by concentrated sulfuric acid and distilled water, and is covered with a cover of the same type as the material from which the pot is made.

Steps to check the car battery

The process of checking the car battery is constantly one of the most important ways to maintain the car battery, which extends the life, and prevent any failures, and the examination is as follows:

The battery is checked by voltmeter, where the engine is switched off and the battery terminal is removed and the battery is cleaned.

The positive voltmeter is connected to the positive terminal of the battery, and the voltmeter tip is usually red.

The negative voltmeter terminal is connected to the negative terminal of the battery

The voltmeter reading is checked

If your battery is in good condition, read between 12.4 and 12.7 volts. If the reading is less than 12.4, your battery needs charging


Types of batteries

There are many types of car batteries, including:

Battery acid

The acid battery is the most common type of battery

Alkaline battery

There are no clear differences between the acid battery and the alkaline battery in the same paneling.

Dry battery

Dry batteries are one of the best types of batteries, and most batteries operate in this type of battery.

How to maintain the car battery

How to maintain the car battery


The car battery is one of the components of the vehicle that starts the internal combustion engine, whether it is gasoline or diesel, and there is another type of batteries appeared recently that are running a purely electric car, that is, electricity. In this article, we provide a detailed description of how to maintain the car battery, and what is the damage of the battery so that we can maintain it.

Causes of car battery damage

Weather fluctuations in winter and summer and the instability of the appropriate temperatures, and here must be maintained through the operation of the panels and be careful to maintain them from high temperature, especially cold or severe and constantly examined.

The dirt of the electrical connections and the accumulation of dirt and dirt on them, so be careful to keep electrical connections clean in the car.


How to keep the battery from corrosion

The need to perform an optical inspection to verify the safety of the battery and the absence of any corrosion in any of its parts because this would preserve the battery life and keep them from any failures causing the explosion. Corrosion appears as a white material on the battery terminals. This material mainly affects the electrical conductivity of the battery. If this material is discovered, it must be cleaned using a special wire brush. Put the grease on it to prevent corrosion and improve the electrical conductivity. It is also possible to add distilled water, which helps to keep them shipped.

Care should be taken to work in a well-ventilated area with adequate temperature and wear special gloves and eye protection tools before you begin to examine the damaged battery to avoid any damage or danger to the person during the examination or cleaning process.

Causes of weak car batteries

One of the main reasons for low battery life and exhaustion is driving. Batteries are short on short journeys. Both the engine and the generator are not given the chance to recharge the battery as needed to be used again. Long distance driving is required to make the battery work better and recharge itself, and an external battery can also be used to provide the necessary comfort
