Choosing the Right Deep Cycle Battery

Choosing the right Deep Cycle Battery for your application is important.

Deep cycle batteries are designed differently to deliver sustained power with low current draw over extended periods of time.

Choosing the Right Deep Cycle Battery

Choosing a Battery

Choosing the right Deep Cycle Battery for your application is important. The size and type of Deep Cycle Battery that you select is dependent on the application and operating conditions. It is important to ensure there is sufficient battery capacity (Amp Hours) to power the equipment you intend to use.

To ensure you select the right battery, download and print a handy Power Estimator document or use the following Quick Guide to assist with determining the right size battery for your needs. If you need more advice or if you aren't 100% sure, get in touch with our friendly team at Supercheap Auto!

Calculating Power

Calculate the Power Consumption (Total Watt Hours) by adding the power consumption (Watts) of each item of equipment and multiplying by the estimated duration of use. For example:

Calculating Power Table

Add 30% safety net to Total Power Consumption.

Total Power Consumption

Convert Power Consumption into Amp Hours (Ah) at 80% Depth of Discharge.

Convert Power

Choose an AGM, Gel or Flooded Deep Cycle Battery rated at least 68Ah.

Difference Between

Do you know the difference between Car Batteries and Deep Cycle Batteries? Car batteries are designed to provide a short, sharp burst of power in order to crank over and start the vehicle's engine - rather than high bursts at short intervals. Deep cycle batteries are designed differently to deliver sustained power with low current draw over extended periods of time. Using thicker battery plates and denser active material, Deep Cycle batteries are designed to withstand repeated charge and recharge cycles.
