What Kind of Battery Is A Car Battery – Type, Size, and Checking
Automotive vehicles or cars are the most common and the most important marvel of technology. Used in everyday life for various purposes, a car is a result of a combined functioning of various technologies. The most important of these technologies that give the start and power to all other mechanisms of an automobile is the car battery.
A car battery is a rechargeable battery (secondary battery) that performs the duty of starting a motor vehicle. It starts the vehicle by providing electrical energy to a starting motor that helps the mechanical parts to move and start the chemical process of combustion in the automobile’s internal combustion engine.
Unfortunately, the most common problem that automobile owners face is that of a discharged or a dead battery. To overcome this problem, everyone needs to know about the type of car batteries available in the market and which type of battery is to be used with which car?
What Type of Batteries Are Used in the Car?
Following are some of the most common car batteries that are used in the market:
Calcium car batteries are a type of lead-acid battery that contains calcium instead of antimony on the battery plates. Calcium batteries contain calcium placed in the negative and positive plates of the battery. Also, calcium batteries are pocket-friendly and are easily available because they use lead instead of antimony. The use of lead makes them require very little maintenance.
Also, calcium batteries are easy to recharge and have the ability to offer the same level of output even after being charged at minimal voltage levels. However, if your car is made for an antimony battery you should not replace it with a calcium battery as that would disturb the battery’s state of charge.
2.Deep Cycle Batteries
Deep cycle batteries are one of the most common types of automobile batteries. The chemical composition of a deep cycle battery is lead-acid and they are designed to provide maximum capacity. The main reason why car owners prefer deep cycle battery is that it is capable of offering uniform current streams as compared to regular batteries that offer short-high current streams.
Deep cycle batteries can get discharged up to 80% of their capacity to provide the maximum output. Their plates are thicker than the regular batteries and the plates should be made up of solid lead and not from sponges.
3.Wet Cell Batteries
Wet cell batteries are called wet cells because they contain a mixture of lead, sulphuric acid, and water. This is the combination of the battery’s electrolytes that are responsible for carrying the chemical energy inside the battery.
Car owners prefer this battery because of its pocket-friendliness which comes at the cost of limitation in their expediency.
Wet cell batteries were used in most cars in the past because of their rechargeability. However, with car technology increasing, automobiles these days require batteries that can offer a uniform and stable power output; a domain where wet cell batteries are not yet efficient.
Present-day automobile applications require a kind of battery that fulfills the constant energy demand of the car without compromising the convenience. ATG batteries are the most popular solution for this problem. ATG batteries came in as a competition to the flooded lead-acid batteries, and the only difference between them is in their electrolyte design.
ATG batteries perform well under extreme atmospheric conditions and come with a built-in valve regulator that regulates the atmospheric pressure according to the battery. These batteries are heavier than usual car batteries and precautions should be taken when installing them.
What is the Size of A Car Battery?
Different battery types have different sizes. Based on the type of battery, the battery sizes are:
1.For Side-Post Batteries
Some of the car manufacturers use a side-post battery. A side-post battery contains cable ends that are fixed on the sides of the battery and not on the top of the battery surface. The battery sizes according to the side-post designs are:
2.Recessed Top Post Batteries
There are a lot of different car manufacturing standards in the world. According to the European car standards, the top posts are placed in the corners so that the battery posts at the top surface of the battery are at an equal height to the battery. These battery frames also contain ventilation systems and are also placed in the car trunk or under the backseat sometimes. Despite these variations, the battery sizes are:
3.Standard Top Post Batteries
Standard Top Post Batteries are the most common type of batteries that are used in Japanese and American cars. They use a typical battery size where the battery terminals are present on the top of the battery. Even though, this is the most common battery type it is very important to specify the exact size of the battery to ensure secure placement of the battery.
The most common battery sizes for standard top post batteries are:
How Do You Check the Car Battery Specification?
Before selecting any type of battery for your car you must know the specifics of your car. Only then you should select any type of battery that fulfills your car's requirements. All of the information about the battery is available on the battery manual provided by the manufacturer or on the battery plate. It is always a preferred option to consult a battery expert that can provide guidance regarding the electrical requirements and the battery safety of the car.
If you do not contain the manufacturer manual then you can make use of the battery guides that the battery retailers contain. The most important things to check in a car battery, on the manual or the battery plate are:
4.Reserve Charge Capacity of the Battery
5.Age of the Battery
Cold-Cranking Amperes of the Battery
