Car Battery Replacement

Vehicle electronics have come a long way. With the modernisation of vehicles, replacing a battery is not always a simple process. Some modern cars possess complex computer systems and circuits which can malfunction if power is disconnected/connected improperly.

The cost of repairing damage by an incorrectly or ill-fitted battery is significantly more than having a professional install a new battery correctly the first time.

How much does it cost to replace a battery?

Replacement cost varies depending on the battery; however, the average cost starts at $190.00, which includes the labour cost. This figure is variable on the type of battery and vehicle.

What options do I have with JDM P/L?

We also offer Outlander batteries through Century, these are a higher cold-cranking amp battery. Cold-cranking amps are designed to help vehicles start in cold climates. These are often chosen by those who travel to remote locations.

We also offer deep-cycle batteries which are designed to be run flat and then charged again repetitively. These are used for people camping/living in a vehicle/running fridges, etc.

Additionally, depending on where the battery is located will determine what options are available. For example, batteries that are located inside the cab of the vehicle must be sealed units (this means they do not dispel gas).

Do you need JDM P/L to replace your battery?

Please simply use our book online page to schedule your replacement.

How long should a car battery last?

Generally speaking, a car battery should last between three and seven years, with five being the average.

The life of a battery will also depend on how often the vehicle is driven, the quality of the original installation, the climate and if the car is serviced on a regular basis.

How do I know when my car battery needs replacing?

The first indicator that your battery needs replacing usually relates to

  • Flickering headlights when starting the vehicle
  • Dashboard lights are dim or not illuminated
  • Electronics (i.e. radio) fail to operate
  • Clicking/ticking noise when starting the vehicle and the engine will not turn over
  • If the car does then start it may stop and your lights will dim down

Red herrings

There are parts of the car that can fail, which have similar symptoms (as described above) that may make a car owner believe their battery has died.

If the following parts fail, they will also cause starting problems:

  • Failing alternator
  • Loose fan belt
  • Dirty battery terminals
  • Fuel pump failure

How we test

Car batteries vary from vehicle to vehicle. We possess a range of different technologies to test different batteries.

We have the Fluke BT521A Digital Analyser that will load test a battery to see if the battery is starting, stopping and charging correctly.

We also utilise a Projecta 1000 Amp Load Tester (analogue, it loads the battery similar to a starter motor) than can be used to test 6, 12 and 24-volt.

Sometimes we are old school and use a voltmeter.

We perform a load test, followed by a charge rate test on the alternator, this checks the alternator is giving the battery enough charge to run the vehicle and charge simultaneously.

From there we can check the fan belt, ensuring it is tight and supplying momentum to the alternator. We also check the battery terminals. These factors help us determine whether the battery requires replacing.

What maintenance steps can I take?

  • Check for leaks
  • Check for cracks
  • Clean terminals regularly
  • Ensure all lights are turned off when exiting the vehicle
  • Top up electrolyte levels (some batteries are low-maintenance, however, levels should still be checked regularly)
  • Use a battery shield to protect the battery from heat, which can cause swelling and overheating

How many volts are in a car battery?

12v.

As an example, if we load test a 12v and it drops below 10v, this is a good indication the battery has expired.

A good & strong battery will hover at 13v.

14.2v is the optimum charging rate.

How many amps are in a car battery?

This depends on the vehicle.

Most commodores and falcons are around 550A. Whereas new diesel will be approximately 600-700A.
