Marine & Boat Batteries
Cranking, deep cycle and dual-purpose marine batteries built for North Queensland heat, salt and vibration — with free in-store fitting and honest advice from people who know boats.
Dual-battery and house-power systems for bigger boats — cranking plus deep-cycle house bank, DC-DC charging and solar, designed and installed for your rig.
Starting vs deep cycle vs dual-purpose
Starting batteries give a big burst to crank the outboard. Deep cycle run electronics and trolling motors steadily. Dual-purpose do both — ideal for smaller boats on one battery.
The ratings that matter
MCA (marine cranking amps) tells you starting power. RC (reserve capacity) and Ah tell you how long your sounder, lights and pumps will run.
Why maintenance-free / AGM
Sealed, spill-proof and vibration-resistant — no topping up, and built to shrug off NQ heat, salt and chop.
Bigger rig? Split crank + house
For boats with lots of electronics, run a dedicated cranking battery plus a deep-cycle house battery so you never flatten the one that starts you home.
Tell us your boat and setup — we'll match cranking or dual-purpose and fit it free in-store.
