Common Causes of Car Battery Failures

Common Causes of Car Battery Failures

A variety of things might cause your car battery to die. The most common causes of car battery failures are not turning off the headlights, power failure, corrosion, or just leaving your car parked for an extended period of time. 

Weak Car Battery Symptoms

  • The engine doesn’t start.
  • The engine cranks slowly.
  • The radio is being faulty.
  • There is no or faint lighting.

What Causes A Car Battery To Die Quickly?

Some of the most causes of car battery failures are:

Inadequately Maintained Battery

Many drivers are unaware that there are actions they may take to properly maintain their car’s battery. So as to ensure you get the best possible performance and lifespan from your battery, you should always keep the battery clean and free of grease and ensure the terminals are showing no signs of corrosion.

Loose Battery Connections 

While driving, a loose battery terminal might prohibit the charge from the alternator from charging your battery. A faulty battery connection might result in the battery discharging from not being charged correctly and can cause other electrical issues.

Leaving The Lights On

People who leave their headlights or interior light on for lengthy periods of time are draining their car batteries. Always make sure to turn off headlights and other accessories whilst the vehicle is sitting idle.

Electrical System Parasitic Drains 

When your car continues to consume power even after the engine has been turned off, this is referred to as a parasitic battery drain. They are typically triggered by a short circuit or a piece of electrical equipment continuing to draw power from the battery.

Problems With The Charging System 

Your vehicle is equipped with a charging system that includes an alternator, a battery, ECU, and wires. If any of these components of the charging mechanism fails, your battery may fail. In any of these scenarios, it is critical to get your vehicle to a reputable auto technician as soon as possible to have the issue fixed. If in doubt, call SW Batteries and have our specialists inspect your vehicle and battery to rule out any other potential issues.
