Frequently Asked Questions

What is a dual battery system and how does it work?

A dual battery system uses two batteries in a vehicle, typically a starter battery and a secondary battery. The system isolates the starter battery so it always has enough power to start the engine, while the second battery powers accessories like fridges, lights or camping gear.

Do I need a dual battery system for camping or 4WD trips?

A dual battery system is useful if you regularly run electrical accessories while the engine is off, such as fridges or lights. It helps prevent draining your main battery, reducing the risk of being stranded and making longer off-grid trips more practical and convenient.

How long will a dual battery last when running accessories?

The runtime depends on the battery size, type and the power draw of your devices. For example, a well-sized system can run a fridge and small electronics for one to three days without driving, but heavy usage or smaller batteries will reduce this time significantly.
