A car battery is one of the most important parts of a car. Without a battery in your car, not only will the car not start but other functions like the AC, music system, and power windows will also not function as intended. While we may think that all batteries are the same, in practice, there are a variety of car batteries that vary on their size and power. It is very important to narrow down the huge variety to your specific requirements and choose what is best for your car.

Lithium-Ion (Li-ion) Batteries

In terms of power to weight ratio it is one of the best options available with high energy density. This battery is popular among hybrid and electric vehicles. These batteries last for half a decade and can be expensive as well. They also get heated rather quickly, requiring complex cooling systems to ensure maximum operating efficiency.

Lead-Acid Batteries

Lead-acid batteries are popularly known as wet batteries. These batteries are also famous for their affordability and can be very easily maintained. The battery life lies between 3-12 years depending on the process of manufacturing. These batteries are used to provide power to all the systems in a car, including the starter, lighting system, and utility functions.

SLI (Start, Lighting and Ignition)

SLI batteries are lead-acid batteries designed to provide a high power output in short bursts. This is ideal for use in automobiles, especially starting, lighting and ignition. Hence, the name of the battery. The design of the battery provides the spike of power required for combustion while also providing power to the infotainment and lighting systems. While SLI batteries can last for years, they should not be discharged completely to prevent damaging the batteries.

Valve-Regulated Lead-Acid Batteries

Valve-regulated batteries are advanced lead-acid batteries that are designed to be even more low maintenance than standard lead-acid batteries. These batteries do not require regular distilled water to be added, which makes maintaining your car more convenient.

How to choose the right battery?

The right battery for your car will depend on your needs and the number of accessories you plan on using in your car. While most batteries are compatible with the electrical demands of your car, it is important to know that the battery you are choosing will meet your car’s requirements.

Here are some important points to remember when choosing your car battery:

* Refer to your owner’s manual to check the preferred battery power and size for your car.
* Ensure the power capacity on the battery is not lower than your current car battery.
* When using higher power capacity batteries, ensure that your car can appropriately charge the battery without additional modification. A larger battery will put additional load on your alternator and will be slower to charge.
* Ensure that the battery you are installing is fresh from the factory. A used battery will have degraded in its power capacity and output, providing a shorter life.
* Ensure all battery connections are secured firmly and that the connectors are free of corrosion.
* Regularly check the terminals to prevent oxidation. Cleaning with distilled water is advised to clean the terminals.
* While not necessary, keeping spare jumper cables and a portable battery charger will help you stay prepared for an unexpected low charge battery.

What happens if I put the wrong car battery in my car?

It is recommended to install the car battery specified in the owner’s manual of your car. Non-compliant batteries could lead to charging issues as well as additional stress on your alternator.

How long can a car battery last without driving?

When you drive your car, the battery is charged by the alternator. A standard lead-acid car battery is designed to last up to 2 weeks without starting or driving the car.

Can a larger capacity car battery be used in my car?

While not recommended, a larger capacity car battery can be used in your car. You will need to ensure that the car’s alternator is not put under additional load while charging the larger battery.

How do I know what car battery to buy for my car?

When buying a new car battery, refer to your car’s owner’s manual to find the battery capacity, output and size of the car battery recommended by the manufacturer.
