A healthy car battery ensures reliable starting, powers onboard electronics, and aids in stabilizing voltage fluctuations in the vehicle’s electrical system. At BAC Auto Centre car battery replacement service involves testing your existing battery, if it doesn’t hold a charge we will remove the old or depleted battery and install the new one, ensuring your vehicle has the power it needs to operate efficiently. Our team will safely dispose of the old battery, install the new one, and ensure all connections are secure and corrosion-free. 

If your battery test shows that there is not a problem with your battery, there is more than likely a mechanical issue with the starting system or the charging system or perhaps there is something constantly draining your battery.

Car Battery Replacement

Your vehicle battery will eventually need to be replaced. When a battery dies, your vehicle won't start, leaving you stranded and in need of a tow or battery boost. Our battery replacement service includes testing your vehicle’s battery life and helping you choose a replacement battery when needed, so you can start your car with confidence.

Alternator Service

If you hear a faint clicking sound when trying to start your vehicle, this is a common indicator of an alternator issue. If left unchecked, your alternator will eventually stop charging the battery, leading to your vehicle not starting when you push the ignition button. Alternator repair involves a technician removing the old damaged part and replacing it with a new one.

Starting System Service

Every time you get into your vehicle, you depend on the starter to turn on your engine. When the starter begins to wear out, you may notice that your engine struggles to crank. If this keeps happening, your engine will finally stop working altogether. One of our technicians will diagnose your starter system to determine which components are causing the issue and repair it.

A car battery typically needs replacement every 3-5 years, though this can depend on your driving habits, climate, and the battery’s condition and type. Key indicators that it’s time for a replacement include a slow engine crank, difficulty starting the vehicle, illuminated battery or check engine light, and a swollen or leaking battery case. Additionally, if you experience electrical issues, like flickering lights or electrical component failure, it might signal that the battery is nearing the end of its life. Always consider the manufacturer’s guidelines and perform regular checks to ensure optimal battery health and timely replacement.

Most vehicle batteries can be changed within 20 to 30 minutes. This includes cleaning the battery tray and terminals, removal of any battery acid and other debris. We recycle all automotive batteries we remove from vehicles.

Unfortunately, car batteries are not a one size fit all, so not every car battery will work in your vehicle. Car batteries come in different sizes, capacities, and technologies, and it’s crucial to choose one that’s compatible with your vehicle’s specifications. A member of the BAC Auto Centre team can help you choose the right battery for your vehicle.

A car that won’t start can be attributed to various issues, often related to the battery, starter, or fuel system. A dead or weak battery is a common culprit, preventing the starter motor from cranking the engine. Alternatively, a malfunctioning starter, faulty ignition switch, or issues with the fuel system can also inhibit the starting process. Additionally, in modern vehicles, problems with the immobilizer or key fob can disrupt the ignition. Always ensure the battery is charged and connections are secure as a first step, and consult the professionals at BAC Auto Centre for thorough diagnostics and resolution of the issue.

I have had my car for over 2 years now and have been going to multiple places for oil changes. This has been by far the best place I have come for an oil change. Dean was extremely friendly and the gentleman who worked on my car showed me one thing that is lose but said it’s not mandatory to fix and will not cause any issues. They did not once push any sale onto me as multiple other places have in the past.
