Car Batteries

Problems, Functions, Cost

The car’s battery is one of the most important components of the vehicle and it should be properly maintained. Failing to maintain the car’s battery can cause other electrical accessories in the car to malfunction adding to your repair cost. Let us look more in detail about how your vehicle’s battery works and what are some early signs to notice to find out if it is failing.

How Does the Car Battery Work?

A typical car comes equipped with a lead-acid SLI battery which stands for “Start, Lighting, and Ignition”.

SLI battery provides a short burst of energy to power your car’s lights, radio, and engine. Once the engine powers through the jolt of energy provided by the battery, the alternator powers the car.

What are the Symptoms of a Bad Battery?

The battery usually dies slowly and will give you plenty of hints to indicate some problems. Here are some of the common symptoms to notice if your the automobile’s battery is not functioning properly.

Dim Headlights

A weak battery may not be able to properly provide power to your car’s headlights. If you notice that your car’s headlights or fog lights are not as bright as before, it may be a sign of a weak battery.

Visible Corrosion on Battery Terminal

The easiest method to check how bad the car battery is, pop up the hood and notice the terminals. If you notice any blue or green crystal-like deposits on the terminals, it is time to replace the battery.

Clicking Sound When Turning on the Car

When the battery is beginning to get weak, it does not create enough energy to start the engine and you will most likely hear a clicking noise. This clicking noise can also be due to a faulty starter or alternator.

Backfiring

A weak or failing battery often causes irregular sparks. These sparks cause the fuel to accumulate in the cylinders and once the built-up fuel suddenly ignites with additional force, the car backfires.

Battery Warning Sign on the Dash

Another most common indication that your car battery needs servicing or replacement is the battery symbol which illuminates on the dashboard. The light can also illuminate to indicate a problem with some other electrical component in the car.

How Much does it Cost to Replace the car Battery?

The average cost to replace a car battery is between $50 to 500 depending on the car model and make.
