An auto battery delivers the voltage that powers various features necessary for your car to operate correctly. If it fails, you might get stranded on the side of the road, resulting in the need for a professional car jump starter. Fortunately, when you know how to identify the signs of a dying battery, you can potentially get a replacement before experiencing roadside trouble. Here are some signs of imminent battery failure. 

How to Tell if Your Car Battery Is Failing

1. Clicking Noises

When you turn the ignition, the battery sends an electrical current to the starter motor, which cranks the engine. If the battery doesn't have adequate voltage, it may not provide enough current to the starter. 

When this occurs, you'll likely notice clicking noises caused by the starter relay trying and failing to turn the starter motor. Replacing the battery can help the car start correctly. 

2. Dim Lights

When your battery nears the end of its life span, your headlights and dashboard lights might seem dimmer than usual. You might also notice weak cabin lights. Getting a new battery can ensure that you see the road and your dashboard clearly while driving at night, keeping you safe.

3. Malfunctioning Electrical Components

Your vehicle's stereo system, power locks, and windows rely on the battery as a source of electrical power. If your battery's resting voltage drops below 12.6 volts, it may no longer provide enough power to these systems. 

This means you might have trouble turning on the radio, locking the doors, or rolling down the windows. A mechanic can use a multimeter to test the voltage and recommend a replacement if the reading falls below the minimum. 

4. Backfiring

A car battery at the end of its life span may intermittently send sparks flying. If these sparks ignite fuel in engine cylinders, small explosions may occur, leading to backfiring through the exhaust system. Having your battery tested and replaced can stop backfiring and possibly rule out other issues, such as faulty spark plugs or engine valves.
