Battery test and replacement, plus full electrical system diagnostics. From simple flat batteries to hard-to-find electrical faults.
Electrical faults are the most frustrating problems on modern cars — intermittent, hard to reproduce, and often misdiagnosed. We start with a proper battery and charging system test, then use professional diagnostic equipment to trace the actual cause of the fault.
A quick Battery Test & Report often catches the issue before you get stranded.
A quick, accurate test of your battery's health and the charging system. You get a printed report — no guessing whether the battery is on its way out.
Battery replacement with the right specification for your vehicle — including start-stop and AGM batteries where fitted. We handle registration/coding for cars that need it.
Full electrical diagnostics — parasitic draw testing, charging system checks, sensor and wiring fault tracing. The tools and time to find the actual cause of the fault.
Most car batteries last 3–5 years in Australian conditions. Short trips, hot summers and stop-start systems shorten that. If yours is over 3 years old and starting is slow, book a Battery Test & Report.
Could be either. A worn battery loses charge naturally, but a "parasitic draw" — something drawing current with the car off — will kill even a new battery. Electrical System Diagnostics traces the draw back to the actual circuit or component causing it.
Yes. Many European vehicles (and some Japanese) need the new battery registered to the BMS after replacement, or you get warning lights and reduced charging. We handle the coding as part of the fit.

"Very thorough and fair, Howard has picked things up that would have cost a lot more later if missed! Great service and he explains everything. We moved interstate and the new mechanic commented on how well the car had been looked after. 10/10"
