How Long Should A Car Battery Last?

December 14, 2021

Finding yourself stuck by the side of the road, at work, at the shopping centre or, worse, in the middle of nowhere with a flat battery, is not a nice situation to find yourself in.


That is why it is important to always have your battery checked as part of every service and to ensure it is replaced when it is starting to lose its ability to hold a charge.


Under ideal conditions, a typical, modern battery will provide three to five years of service life. There are many factors that can cause a battery to degrade before its shelf life, though, which is why it is important to care for your battery just like you would other car components.

What Can Shorten The Life of A Car Battery?

Signs That Your Battery Might Be Running Out of Life

When you notice any signs that your battery might be failing, it is important to get it replaced as soon as possible. Some of the symptoms to look out for include:


Slow wipers: Your windscreen wipers need a fair bit of power to operate. If you switch them on and they are running slower or struggling to operate at a full pace, this is a sure sign your battery is starting to fail. 


Difficulty starting your car: If you crank your vehicle and it turns over slowly or your engine doesn't start at all, either your battery or alternator is likely the issue.


The radio doesn't work: While you might have enough charge to start your car for now, if your radio is not coming on, then it is likely your battery is on the way out.

Timing is everything when it comes to pink slip inspections. Booking your inspection early helps you avoid last-minute stress and provides ample time to address any issues.


  • Book Ahead: Aim to schedule your inspection a few weeks before your registration renewal deadline to allow room for unforeseen repairs.
  • Choose a Reputable Mechanic: Select a licensed inspection station with a solid reputation for reliable and thorough assessments.


This approach ensures that you’re well-prepared for any necessary follow-up steps, such as repairs, before the deadline.
