Battery Testers

Battery testers are a smart way to stay ahead of electrical issues. These tools show if your battery can hold charge and deliver power when it matters. They're ideal for keeping cars, 4WDs, caravans, and heavy setups running without surprises. The range includes models that work with 6V, 12V, 24V, and 48V systems, covering everything from small vehicles to dual battery systems.

You’ll find digital testers with clear screens, load testers with colour-coded meters, and even options that print out results. Some units can also check alternators and starters, making them useful for full vehicle checks. Whether you're after something simple for quick tests or a tougher tool for workshop use, there’s a model to suit. You can also grab leads and printer paper to keep your gear ready to go.

How does a battery tester work and what does it do?

Battery testers check the condition of your battery by measuring voltage, internal resistance, or how the battery responds under load. Load testers apply a short burst of current to see how the battery performs under stress. Digital testers use sensors to read charge levels, resistance, and cold cranking amps (CCA) without draining the battery.

Some testers also check related systems like the alternator or starter. This helps confirm whether the issue lies with the battery or somewhere else in the electrical system.

When should I use a battery tester to prevent problems?

It’s worth testing your battery before a big trip or when the seasons change. Cold weather and long drives can push a weak battery over the edge. A quick check gives you peace of mind before heading out.

It’s also smart to test after adding new gear like lights, winches, or fridges. Extra load can wear out a battery faster than you think. Checking early means you can upgrade or replace the battery before it lets you down.

What is the capacity of a battery tester?

Capacity tells you how much power a tester can handle during a check. Load testers are rated by the amps they apply. A 100A tester works well for small to medium batteries around 40 to 80Ah. These are common in cars, motorcycles, and small 4WD setups. For bigger batteries over 100Ah or dual battery systems, a 500A load tester gives more accurate results without stressing the tool.

Digital testers are rated by their CCA range. That’s how many cold cranking amps they can read. Some models go up to 2000CCA which suits large deep cycle batteries used in caravans, boats, or touring setups. A smaller tester rated to 1000CCA is still fine for most standard vehicles.
