    Test Before You Assume

    Without testing, you don't know whether the issue is the battery itself, dirty terminals, or something else. Our mobile van comes to your location, tests the battery voltage and cleans the terminals, so you know whether a jumpstart will hold or a replacement is needed.


    Replacement on the Spot

    If the battery needs replacing, we can supply and fit a new one on the spot in many cases. For batteries over three years old, it's worth having a health check before a long trip. Most callouts are quick, with testing, cleaning and a jumpstart done at your location.


    Key Takeaway

    If your vehicle won't start, call Big J Mobile Tyres Service on 0485 075 056 for a mobile battery test and jumpstart across western Melbourne.
