Frequently Asked Questions
Here’s what every boatie should know about marine batteries, from choosing the right type to keeping them performing.
How do I choose between a starter and deep-cycle marine battery?
Starter batteries deliver short bursts of power for engine ignition, while deep-cycle batteries provide steady energy for electronics like lights, fridges and navigation gear.
Many boat owners opt for a dual-purpose battery for convenience, especially on smaller craft. Larger vessels, however, often benefit from using both types – one dedicated to starting, another to running auxiliary systems.
The choice depends on your setup, power draw and how often you’re out on the water.
How can I prevent corrosion on my marine battery terminals?
Moisture and salt are the biggest threats. Keeping terminals clean and coated with a protective spray helps prevent rust and voltage loss.
Check cables and clamps regularly for green or white residue (a sign of corrosion). Mounting your battery in a ventilated compartment and securing it tightly reduces exposure to spray and vibration.
A quick rinse with fresh water after each trip also helps keep everything in good shape.
Why does my marine battery drain even when the boat’s off?
Many boats have systems like bilge pumps, alarms or radios that continue drawing power even when not in use. Over time, this can flatten a battery. Installing a battery isolator switch allows you to cut power completely between trips.
If the issue persists, a parasitic draw test can identify which circuit’s responsible, preventing unnecessary replacements or damage to the electrical system.
Offshore Power You Can Count On
Marine batteries power your engine, lighting, navigation gear and more, often for hours at a time. That’s why choosing the right type is crucial. We stock maintenance-free options that handle heavy vibration, long discharge cycles and harsh marine environments without skipping a beat.
Every installation includes testing to confirm your charging system’s working correctly and that your battery’s protected from corrosion or short circuits.
AGM Batteries: Built for Marine Conditions
AGM (Absorbent Glass Mat) batteries are a popular choice for boaties who want reliable power without the maintenance. Designed to handle vibration, salt and humidity, they’re perfect for life on the water.
Unlike traditional flooded batteries, AGMs are completely sealed, so there’s no topping up or spill risk. They recharge quickly and hold power longer, making them ideal for boats with sound systems, fridges or navigation gear. AGM batteries deliver dependable energy so you can spend more time cruising and less time checking connections.
Caravan Batteries Made for Endless Adventures
Life on the road shouldn’t come with power worries. Our caravan batteries are built to handle Australia’s changing conditions, from humid coastlines to dusty inland stops. We fit trusted deep-cycle options that keep your lights, fridge and gear running day after day.
