Runtime and Load Planning

Nominal energy is approximately 1,200Wh, but usable runtime is lower and varies with discharge rate, battery condition, temperature, wiring loss and the manufacturer’s recommended depth of discharge. Repeated excessive discharge can shorten AGM service life.

The 1,080A figure is a five-second maximum, not a continuous-current rating. Do not use it to size an inverter or continuous appliance load. Check the battery’s permitted continuous current, cable size, fuse and voltage drop for the intended system.

Installation and Storage

Measure the installation area before ordering and allow for the battery’s 25kg weight. Secure the battery, protect the positive cable with a correctly rated fuse and follow the manufacturer’s ventilation and orientation guidance. Recharge after use and periodically during storage as directed in the manual.

Frequently Asked Questions

Can this battery run a caravan fridge?

It may suit a compatible 12V fridge when the fridge’s measured daily watt-hours, start-up demand and required runtime fit the available battery energy and charging input.

Is it suitable for engine starting?

This product is listed as a deep-cycle storage battery. Do not use it as an engine-starting battery unless the manufacturer specifically approves that application.
