Car Battery Replacement

How much does a car battery replacement cost?


The battery is your vehicle's main source of electrical power.

It gives power to the starter motor, fuel pump, engine control computer (when the driver turns the key), and allows the vehicle to start.

It also supplies power to the radio, headlights and other electrical components inside the car which provides entertainment and information to the driver.

It is important to make sure your battery and charging system is in good working order, otherwise, you may get stranded with a vehicle that won’t start!

The average battery replacement starts at around $150, and depending on the type of vehicle, can increase to $550+

What is a battery?

The battery is a large electrical storage device filled with electrolyte and lead plates, and is charged by the alternator when the vehicle is running. It is joined into the cars electrical system through two posts that protrude through the top of the battery. This allows the charge to be transferred through the vehicle to where it is needed. 

Symptoms your battery may need to be replaced

  • Vehicle will not start
  • Radio or headlights will not operate or are dim
  • Vehicle sluggish to start

How is a battery replacement performed?

Our mechanics will remove and replace your vehicle's battery, including recycling your old battery and carry out a test on the charging system to make sure everything is in working order.

Tips to remember

  • You may lose radio and clock settings during this repair, so make sure to have any necessary radio PIN codes handy to restore operation.
  • Vehicles equipped with ‘Stop-Start’ systems, which shut the engine down in certain situations to save fuel, have specially designed batteries that can withstand the extra load that is put on the system. These vehicles are fitted with heavy duty batteries, and failure to fit the correct battery may cause issues with the system, and premature failure

Why it’s important to have your battery replaced

Having your battery inspected and charging system checked will give you peace of mind whenever you turn your vehicle off.

Operating a vehicle with a failed battery or charging system can be dangerous. Your vehicle may stop suddenly, endangering your family and other motorists around you.
