While it takes many auto parts to keep a car running, it all starts with the battery. This device possesses a considerable charge, providing enough power to start the engine and support other electrical components, including the lights, radio, and air conditioning. Even though batteries are powerful, they do not last forever. Here’s what drivers should know about car batteries to help them keep their vehicles running.

How Do Car Batteries Work?

The inside of a car battery consists of a sulphuric acid-water fluid and metal plates. When the vehicle ignition is started, a signal is sent to the battery to trigger a chemical reaction between the acid and plates. This reaction results in a flurry of electrons, which produces useable electricity.

The electricity is directed out of the battery through a negative terminal connected to the car’s electrical system. This energy flows through the system to start the engine and power up other vehicle accessories. The flow completes its circuit by returning the positive battery terminal, where the energy is used to recharge the device.

Over time, however, batteries lose their charge and are no longer able to start a car. Depending on the product, a new battery may last anywhere from three to five years.

What Are the Signs You Need a New Car Battery?

You can usually tell that a battery is failing by the way a car is managing its electricity. If you frequently have trouble starting the engine or notice that dashboard lights are flickering, you’re likely due for a replacement.

While the occasional jumpstart can often restore the charge, doing it regularly is a sign that the battery is nearing the end of its life span. Batteries should also be replaced when they show signs of damage, such as a swollen case or leaking fluid.

How Are Batteries Replaced?

Compared to other auto parts, batteries are fairly simple to remove. However, since these devices contain potentially harmful acid, always wear gloves or let a professional handle the task.

Before removing the battery, detach the cables from their terminals, and unlatch the clamps that secure the case. Carefully lift the battery out, and clean the cable connectors, if necessary. Place the new battery in the socket and secure the clamps. Once the cables are reattached to their appropriate terminals, the battery should be ready to go.
