Signs You Should Replace Your Car Battery

The average car battery lasts about 4 years. If you’ve had the same battery for a long time and it’s showing signs of wear and tear, you might want to think about replacing it. The good news is that replacing a car battery is an easy task that can be done in under an hour. But before you get started, there are some things to consider first before getting car service in Melbourne.

Difficulty starting your vehicle

If you have to crank the engine for a long time, it’s a sign of a bad battery. If your car is difficult to start, or if it won’t start at all, there’s an issue with the battery. You might not think that this is something you should be concerned about, but if your battery dies or isn’t strong enough to power your vehicle like it used to, then you’ll have trouble starting it up again.

When the weather gets colder and wetter (as we’re reaching now), batteries lose their ability to hold a charge as well as they can in warmer weather. This means they need replacing more often during winter than any other time of year.

Issues with your electrical system

An electrical system problem is a common symptom of a bad battery. Electrical problems can include:

  • Your car won’t start at all.
  • The engine cranks slowly, or makes a clicking sound but won’t start.
  • Cigarette lighters don’t work when you flick the switch.
  • Headlights dim when you turn on the interior lights or blinker indicators. If you’re experiencing any of these issues, you may need to replace your car battery.

An unpleasant odour

If you smell a foul smell coming from the battery, it may be leaking acid. This can lead to corrosion and damage to your car. Battery acid can also damage the environment, so avoid spilling it on the ground by taking care when removing your old battery. If you spot any discolouration in or around your engine compartment (such as green or white), this could indicate an issue with your charging system.

Warning lights on your dashboard

  • Check the battery’s voltage. If your car’s battery is less than 12.4 volts, it may be time to replace it.
  • Check the connections between the alternator and the battery terminals. If they’re loose or corroded, they could be causing a problem with your electrical system.
  • Check your alternator belt. This can cause a similar issue as checking your connections between the alternator and battery terminals (see above), but this one requires a little more hands-on work: check for cracks in the belt itself; make sure that it’s not frayed or cracked; if there are any cracks or frays in either part of this belt—between the pulley on top of the engine and power steering pump pulley on the bottom—then it needs replacement immediately!

There’s a right and wrong way to replace a car battery.

When replacing a car battery, there are some things you should do and some things you shouldn’t. Following these tips will help ensure that your new battery is installed properly and continues to provide electricity for years to come:

  • Use the right tools. A variety of tools are available for removing and installing car batteries, but they can be expensive if purchased individually; it’s best to buy a kit that includes everything you need at once. Use quality equipment because cheap tools may break or make installation more complicated than necessary.
  • Check the terminals on both ends of the old battery before taking out its connections—you want to avoid damaging them when removing its cables (a common mistake made by DIYers). Also, check that they’re clean before reconnecting them; crud can inhibit current flow by blocking contact points between two pieces of metal during charging cycles which makes powering an engine more difficult than it has to be!
  • Ensure that all connections are tight after reassembling both ends; loose connections lead directly back into poor performance in this case too.


In summary, we’ve discussed the signs of a bad battery to know whether you need car service to prevent future vehicle issues. Hopefully, this article has helped you determine whether you need car service in Melbourne or not.
