Deep Cycle batteries are great for meeting the power requirements of your accessories. Ensuring that your deep cycle battery has the capacity necessary for your equipment is important.

We have developed our Deep Cycle calculator to help you decide on the battery solution that best fits your needs.

Simply enter the power consumption in Watts for each of your devices along with the anticipated usage per day and we will present you with the best matching battery from our extensive range.

Terms & Conditions

The information entered into this calculator is intended to help estimate a suitable battery size for your application and is provided as a guide only.

This calculator is designed for 12-volt battery systems and includes Flooded, AGM, and Lithium battery options.

The calculation is based on estimated daily power consumption and assumes the battery is recharged correctly each day with sufficient charging input to return it to full charge. Failure to do so may result in reduced performance and premature battery failure.

When changing battery type, both the battery and charging system must be checked for compatibility. This includes alternators, battery chargers, DC to DC chargers, solar regulators, and other charging devices.

Lithium batteries must only be used where the battery management system, charging profile, voltage limits, and discharge limits are suitable for the application. Not all systems designed for lead-acid batteries are compatible with Lithium batteries.

Suitable clearance, ventilation, and air circulation must be provided where required for the battery type and installation, ensuring heat can dissipate safely and manufacturer requirements are met.

Battery systems should be specified and installed by a qualified business or technician. This calculator is not intended for large, complex, or customised systems.

Final battery selection remains the responsibility of the installer and end user.
