What is a car battery?

A car battery is actually a battery whose function is to store and produce electricity through various chemical processes.

It is used mainly for starting the car engine and for the main power supply of all electrical components. There are different types with different power, technology and size. Their operation depends on different vehicles. Battery life is about 4-5 years.

Types of car batteries

You should be aware that there are different types of car batteries. It is important to familiarize yourself with their characteristics in order to make the right choice.

Wet battery

The wet battery is the most common type and therefore the most used. What stands out is that it does not require maintenance or any special care.

The disadvantage of this type is that if the entire battery charge is consumed, it must be replaced. You need to be aware of its status to reload as needed.

Calcium battery

This type of battery is known for its long life.

This is because its plates are made of calcium alloys, which reduce the loss of fluid from the battery. The calcium battery has one minor drawback: it does not withstand overload.

VRLA Gel Battery (Lead Acid)

It can be said that this type of battery is the most durable because it is designed so as not to lose any liquid. The box is sealed and under some pressure. The gas is in a liquid state and its pressure is regulated by valves.

It is also known as a hybrid car battery because it is the most used in this type of vehicle. There are two types of VRLA batteries: with gel and with glass absorbent pad. The former stands out because it can be recharged after a full discharge and because it withstands temperature changes. The second stands out with a strong startup power.

Deep cycle car battery

This is a type of battery mainly used for industrial and electric vehicles. Not recommended for standard diesel and petrol vehicles.

Can be used on some hybrid vehicles.

Lithium-ion car battery

The lithium-ion battery is characterized by being lightweight and with much better autonomy.

The use of such a battery is rare. It is found in some electric cars and in some more expensive models.

how to choose car battery?

How to choose a car battery?

You can find many different brands and models of car batteries on the market. Therefore, it is extremely important to know the most relevant features of these devices. This will make sure that you choose a model that will offer you optimum performance. 

Below we have outlined the main things to consider when choosing a battery for your car.


One of the most important things to check its tension. It’s about the power with which electricity circulates. It is important to choose the right voltage according to the car you own.

We have to point out that cars use 12-volt batteries, and trucks and other larger vehicles like buses use 24-volt batteries, for example. With this in mind, it is essential that you properly check the product description and specifications to make sure you are purchasing the correct voltage battery. There are models that offer higher voltage to get started, such as sports cars, but these are special cases.

Reserve Capacity

Rated battery capacity refers to the amount of electrical power (amps) that the device uses to drive the starter at 0 ° C.

The capacity of the battery used depends on the electrical elements of the car. For example, a small city petrol car will need a 50 or 55Ah battery. But for a larger class of limousine car or with a more powerful engine, a 95Ah or even 100Ah battery will be required.

It should be noted that diesel engines require more current during startup than petrol. The diesel requires an average 75Ah car battery (minimum 70Ah), while a petrol car will have a 60 to 70 Ah battery. You have to keep in mind that everything depends on the electrical devices it includes. If your car does not have power windows, air conditioning or power mirrors, for example, a battery between 40 and 45 Ah may be sufficient.

Startup Power

Another element to keep in mind is the startup power, a fact that is very important when starting the car for about 30 seconds. This feature clarifies what kind of electrical power is able to generate the battery at a given moment at -18 degrees and without reducing the maximum voltage, which is 12V for cars and 24V for trucks.

You will see the startup power marked with numbers like 400, 600 or 720 amps. This factor is especially important during cold winter days, so it is best to buy a battery with a high startup power so that you do not have problems starting your car at low temperatures.

The size

When replacing your old battery with a new one, you should consider its size. You must select a model according to the size of the battery-specific space.

Therefore, it is essential to pay close attention to its height, width and length to ensure that you can successfully mount it in your car.

There are models of cars that work with different sizes of batteries, but most do not. Therefore, there is a good chance if you do not check the size to buy a different model that is not responsible for your car.

How to change a car battery?

Changing the car’s battery is one of the things owners can do at home without the need for a mechanic. This procedure is not complicated, but to give you a much clearer idea, we have detailed the steps you need to follow.

Turn off the engine

It may seem obvious, but it is better to mention it. If you are going to replace the car battery with a new one you have to switch off the engine. You must also make sure that you have switched off all electrical devices such as headlights, gauges, radios, CD players, and the like, which will reset and return to their original settings.

Tools needed

The battery is attached to the car with a bolt. Loosen it by hand, sometimes it may not be very easy as it is quite tight. Depending on the type and size of the bolt, each car will need a different type of wrench.

Remove the old battery

To do this, you need to remove the battery cover to reach the poles. You must first release the negative terminal and remove it, then release the positive. This is simple since most terminals have only one nut with a nut. After you have released everything, you can remove it from the car battery holder.

Insert the new battery

After removing the old battery, you must put the new one in the same position. You must insert each holder by following the opposite steps when removing the old one. When you have positioned the battery well and tightened it properly, you must connect the vehicle’s power cables. First, connect the plus terminal, then the negative terminal and tighten them tightly.

How to charge a car battery?

Some battery models are not damaged but are discharged. In this case, they need to be charged so that they can work again.

If you are wondering how to charge a car battery, you should know that this can be done mainly by using a battery charger or starting the engine with power cables and another battery. In the second variant, the battery will be charged by the running engine.

In both cases, the procedure is simple, but precautions must be taken to avoid accidents.

Charge the battery with a charger

  • Remove the battery from the car by following the steps above (always switch off the negative terminal first and then the positive terminal).
  • Put it in a ventilated place.
  • Plugin the red cable clip of the charger with the positive terminal of the battery and the black pin with the negative terminal.
  • Select the correct voltage if the charger provides this function.
  • Turn on the charger and make sure that the ampere indicator decreases as the battery is charged.
  • After charging, you will need to unplug the battery charger by removing the clips in the reverse order in which you put them.
  • Install the battery back into the car following the replacement steps.
