5 Definite Signs to Identify that It’s Time to Replace Your Car Battery


It’s not wrong to say that your car’s battery is like its vital organ like brain or heart; without battery, your car can’t remain alive and running. In that case, it becomes necessary to understand it as much as you can and more importantly know the signs showing that it needs to be replaced.


The standard battery, in vehicles manufactured in 1952 and later, is a wet-cell battery. This is a plastic cube which contains lead and sulfuric acid and two terminals emerging out of the top or a side.

An old battery or loose cables can give rise to major problems that make it seem that there is something very complicated and wrong with your car. Even experienced technicians may be stumped by a simple issue of a battery past its prime, till they understand that they have ruled out all other possible issues.

These are indeed moments of repenting when you understand that you could have saved an hour, simply by checking the battery and its cables.

On the other hand, if it’s quite clear that your battery is dead, it only needs a jump, either by yourself or by professionals providing roadside assistance in Sydney by Roadside Response, for example.

Warning Signs that Your Battery is Dead or About to Die

  1. Your Engine Doesn’t Start, Only Cranks

If when you turn the key, your engine turns over or cranks, but doesn’t start, battery is the most likely culprit. It may be your starter or something else too, but 94% of times, it’s the battery, even though the car is cranking pretty vigorously.

Even if it’s seen on an ammeter (device to measure current) that the battery is fine, it can still be short by a few volts than what your car needs to run properly.

When you find that your car won’t crank hard enough to start, you should use a jump-starter box or jumper cables to make it run again.

Once your car starts, detach the cable and let your engine run for half an hour so that your alternator can charge up your battery.

  1. You See No Crank, No Lights, No Start

This is a quite clear-cut situation to diagnose and it’s an even more powerful sign that your battery is faulty. Your battery provides power to all the lights and accessories in your vehicle, particularly when the alternator is not working. Hence if your vehicle just appears to be totally void of all symptoms of life, your battery is the first thing you should check.

  1. It Works Fine One Day, but Won’t Work the Next Day

If starting of your vehicle has become an intermittent issue for you, it indicates that either your battery terminals are broken, loose, calcified or corroded, or you have a parasitic draw (there is a leak of your power on some gizmo that’s running when it’s supposed to be off or by a wire that’s in touch with something which it shouldn’t.

First check the battery cables, as they are typically the prime culprits and are also easier to check on your own

Make sure that the cables fit snugly and securely on battery posts. They should not be able to be wiggled even an inch. Also watch if the cables reaching the terminals are not falling apart or frayed; if they are, change them as quickly as you can.

  1. You Have Amply Jumped It Already

If you need to jumpstart your battery more than three times in one single week, it’s an indication that you should newly buy car battery in Perth from Roadside Response, for example. Even a pretty new battery can die quickly if it is jumped more than thrice in a week, as using jumper cables or jump box can be hard on your battery.


  1. Cold Cranking is Tough Work

You should find a label on your battery mentioning a number for “Cold Cranking Amps”. These are responsible for providing your engine adequate energy to get started the first time in the day, often called “cold cranking”.

So, it’s not surprising that an early symptom that your battery is dying, a symptom most people miss, is that you are putting excessive energy already into starting your car. You can hear nothing but many weak rotations of the engine and afterwards the engine suddenly starts and sustains an idle. With these signs the battery is notifying you that it’s about to retire.
