Batteries &
charging systems.

Flat battery? Won't hold a charge? Strange parasitic drain? We test properly, diagnose the real cause, and replace with quality batteries on-site — no tow needed.

Overview

A flat battery is rarely just a flat battery. It might be the battery itself, a failing alternator, parasitic drain from an accessory, corroded terminals, or a wiring fault. Replacing the battery without diagnosing the real issue just kicks the can down the road.

We carry quality replacement batteries on the truck for most common vehicles, along with proper testing equipment to check battery state-of-health, alternator output under load, and parasitic current draw. Get it done properly the first time.

What we handle

  • Battery testing under load — proper assessment of state of charge and state of health
  • Quality battery supply and on-site replacement
  • Charging system diagnostics — alternator output, voltage regulation, ripple testing
  • Parasitic drain testing for batteries going flat overnight
  • Battery terminal repair, replacement and corrosion treatment
  • Start-stop and AGM battery systems
  • Auxiliary, deep-cycle and dual-battery setups for 4WDs, caravans and campers
  • Hybrid 12V auxiliary battery service

When you need this

  • Slow cranking or clicking when you try to start
  • Battery keeps going flat, especially after sitting overnight
  • Battery warning light or charge-system light on the dash
  • Dim or flickering headlights and interior lights
  • Battery is over 4–5 years old and you want it checked
  • Adding a dual-battery system or upgrading for accessories

Our process

We test the battery itself, then the charging system, then the parasitic drain — in that order — because the real cause could be any of them. If it's a battery, we'll fit a quality replacement on-site, register it with the vehicle if needed (modern cars require this), and clean up the terminals and connections properly.

Why us for batteries

We don't just guess based on age. We test properly, identify the actual issue, and only replace what needs replacing. The batteries we fit are quality brands suited to your vehicle and driving — not the cheapest unit on the shelf.
