Car Battery in Geelong

More Than Just a Battery Swap

Your car’s battery works with the starter motor and alternator to keep everything powered up—from starting the engine to running your lights, radio, and more. But when something’s off in the start or charge system, it’s not always just the battery. At JJ’s Garage, we check everything properly—battery condition, voltage, alternator performance, and starter motor health—so we don’t just patch the problem, we solve it.

• Full vehicle start & charge checks
• Quality battery replacements
• We handle ignition issues too

We stock dependable battery options for all makes and models, and we’ll walk you through what your vehicle actually needs, without the upsell. If your car’s been sluggish to start or showing signs of electrical trouble, book a diagnostic and battery test with our team today.

Battery Start & charge

Your vehicle’s battery is the heart of the start and charge system, supplying the power to crank the engine and keep your electrical systems running. At JJ’s Garage, we offer fast battery testing and replacement, using reliable options suited to your vehicle. We also check charging levels to make sure the battery is functioning as it should, not just temporarily holding a charge.

If your car is slow to start, showing dashboard warnings, or losing power unexpectedly, we can pinpoint the issue and get you moving again.

A faulty alternator can drain your battery and cause electrical problems like dim headlights or malfunctioning accessories. We test alternator output, check for worn components, and repair or replace units where necessary. By addressing alternator issues early, we help prevent breakdowns and extend the life of your battery and electrical system.

Our goal is to restore reliable charging performance and ensure your vehicle stays powered up wherever you drive.

Starter motors are crucial for getting your car moving, and when they fail, you’re not going anywhere. Symptoms like clicking noises, slow cranking, or no response at all can point to a failing starter. Our team inspects and repairs starter motors quickly, using quality components for lasting performance. Whether the issue is electrical or mechanical, we’ll diagnose it accurately and get your car starting smoothly again.

Ignition problems can make starting your car inconsistent or cause it to misfire while driving. We diagnose faults in coils, spark plugs, and related wiring, repairing or replacing parts to restore dependable performance.



Ignition repairs are often linked with start and charge issues, so we check the whole system to ensure your fix is complete, not just temporary. This keeps your car running reliably and reduces the risk of future breakdowns.
